This suit was brought by the United States against the petitioners in the District Court of Wyoming to secure the cancellation of an oil and gas lease made by the United States to the Mammoth Oil Company April 7, 1922, and to set aside a supplemental agreement made by the same parties February 9, 1923. An accounting and possession of the leased lands and general relief were also demanded. The complaint alleged that the lease and agreement were made without authority of law and in consummation of a conspiracy to defraud the United States. The District Court held that the transaction was authorized by the Act of June 4, 1920, 41 Stat. 812, 813 (34 USCA § 524 (Comp. St. § 2804i)), found that there was no fraud, and dismissed the case. 5 F.(2d) 330. The Circuit Court of Appeals sustained that construction of the act; but, on an examination of the evidence, held that the lease and agreement were obtained by fraud and corruption, reversed the decree, and directed the District Court to enter one canceling the lease and agreement as fraudulent, enjoining petitioners from further trespassing on the leased lands, and providing for an accounting by the Mammoth Oil Company for all oil and other petroleum products taken under the lease and contract. 14 F. (2d) 705.

The lease covered 9,321 acres in Natrona county, Wyo.-commonly known as Teapot Dome-being Naval Reserve No. 3 created April 30, 1915, by an executive order of the President made pursuant to the Act of June 25, 1910, c. 421, 36 Stat. 847, as amended August 24, 1912, c. 369, 37 Stat. 497 (43 USCA §§ 141-143 (Comp. St. §§ 4523-4525)). The part of the Act of June 4, 1920, relied on to sustain the lease contains the following:

'Provided, that the Secretary of the Navy is directed to take possession of all properties within the naval petroleum reserves * * * to conserve, develop, use, and operate the same in his discretion, directly or by contract, lease, or otherwise, and to use, store, exchange, or sell the

[Argument of Counsel from pages 23-31 intentionally omitted]

oil and gas products thereof, and those from all royalty oil from lands in the naval reserves, for the benefit of the United States: * * * And provided further, that such sums as have been or may be turned into the Treasury of the United States from royalties on lands within the naval petroleum reserves prior to July 1, 1921, not to exceed $500,000, are hereby made available for this purpose until July 1, 1922.'

March 5, 1921, Edwin Denby became Secretary of the Navy and Albert B. Fall, Secretary of the Interior. May 31, 1921, the President made an order purporting to commit the administration of all oil and gas bearing lands in the naval reserves to the Secretary of the Interior, subject to the supervision of the President. The lease and agreement were signed for the United States by Fall as Secretary of the Interior and by Denby as Secretary of the Navy. The evidence shows that the latter was fully informed as to the substance of the transaction, and it is not necessary here to consider the validity or effect of the executive order.

The purpose and scope of the lease and agreement may be indicated by a statement of their principal features. The preamble to the lease stated that it was the duty of the government to secure and store oil for the navy; that the government desired to avoid the loss of oil resulting from the drilling of wells outside the reserve, to create a market and receive the best prices obtainable for royalty oil from the Salt Creek field (adjoining the reserve on the north), to exchange royalty oil from the reserve for fuel oil for the navy, and to secure facilities for the storage of such fuel oil; and that the government proposed to secure these objects by entering into a contract providing for the development and exploitation of the oil and gas within the reserve and for the construction of a pipe line if necessary, for the transportation of royalty oil from the reserve and from the Salt Creek field.

The lease granted to the company the exclusive right to take and dispose of oil and gas so long as produced in paying quantities. The lessee agreed to drill test wells, and, after their completion, fully to develop the reserve, to construct, or cause its nominee to construct, a common carrier pipe line (about 1,000 miles in length) from the leased lands to a line from the mid-continent field to Chicago; to pay as royalties specified percentages of products taken from the land; to purchase all royalty oil when and as produced, and in payment to set up an oil exchange credit to the lessor and issue certificates showing the amount and value of royalty oil received by lessee. It was provided that lessee would redeem the certificates by giving lessor credit on its obligations to lessee for the construction of tanks to store fuel oil for the navy under the agreement contained in the lease for the exchange of crude oil for fuel oil storage, or by delivering to lessor fuel oil or other products of petroleum for the use of the navy, or by cash under certain conditions. And it was agreed that the lessee, when requested by the lessor, would construct or pay the cost of constructing steel tanks necessary for such storage; that lessor would pay in oil certificates of face value equal to such cost; that in exchange for crude oil lessee would deliver fuel oil and other petroleum products for the navy at places1 on the Atlantic Coast, the Gulf of Mexico, and at Guantanamo Bay, Cuba. Lessee agreed diligently to drill and continue operations of oil wells unless by the Secretary of the Interior permitted temporarily to suspend operations. And it was provided that, with the consent of the Secretary of the Interior, the lease might be terminated. By a separate agreement dated December 20, 1922, the lessee designated, and the lessor accepted, the Sinclair Pipe Line Company as the nominee of lessee to construct the pipe line, having a daily capacity of 40,000 barrels.

The supplemental agreement of February 9, 1923, relates to storage tanks to be provided by the lessee. It deals with four projects covering construction work at Portsmouth, Melville, Boston, and Yorktown. The total capacity-some expressed in tons and some in gallons-to be constructed at these places was sufficient to store 2,550,000 tons of fuel oil, 37,500 tons and 625,000 gallons of Deisel oil, 26,500 tons and 2,330,000 gallons of gasoline, 13,800 tons and 1,161,000 gallons of lubricating oil. The lessee agreed to provide the tanks and fill them in exchange for royalty oil certificates. The government was not obligated to lessee otherwise than to deliver it oil certificates for redemption in accordance with the lease, and, until the agreement was fully performed, all certificates received by the government were to be used for constructing and filing storage for fuel oil and other petroleum products. And it was further provided that upon completion of these projects other facilities for the storage of petroleum products required by the navy were to be constructed and filled by the lessee.

The evidence shows that the storage facilities to be furnished under the lease were to be complete reserve fuel stations, such as are known in the Appropriation Acts as 'fuel depots'; that the arrangement to use royalty oil to pay for such construction was made for the purpose of evading the requirement that the proceeds of the royalty oil, if sold, be paid into the Treasury, and to enable the Secretary of the Navy to locate, plan, and have constructed fuel stations that had not been authorized by Congress; that the approximate cost of construction so to be done on the Atlantic Coast would be at least $25,000,000, of that on the Pacific under arrangement with the Pan American Petroleum & Transport Company $15,000,000, and for the whole program-including the products to be put into these fuel depots when constructed-a little in excess of $100,000,000. The cost of the pipe line is not included in any of these figures. It was not deemed to be a facility merely for the development of the reserve, but was desired by those acting for the government for the transportation of oil obtained in that part of the country, to create competition in the oil market, and as an instrumentality for national defense in case of war.

A construction of the act authorizing the agreed disposition of the reserve would conflict with the policy of the government to maintain in the ground a great reserve of oil for the navy. Joint Resolution, approved February 8, 1924, 43 Stat. 5. It would restore to the Secretary of the Navy authority of which he had recently been deprived, to construct fuel depots without express authority of Congress. Act of August 31, 1842, 5 Stat. 577 (R. S. § 1552); Act of March 4, 1913, 37 Stat. 898. It would put facilities of the kind specified outside the operation of the general rule prohibiting the making of contracts of purchase or for construction work in the absence of express authority and adequate appropriations therefor. R. S. §§ 3732, 3733 (41 USCA §§ 11, 12 (Comp. St. §§ 6884, 6886)); Act of June 12, 1906, 34 Stat. 255 (41 USCA § 11 (Comp. St. § 6885)); Act of June 30, 1906, 34 Stat. 764 (31 USCA § 627 (Comp. St. § 6763)). It would be inconsistent with the principle upon which rests the law requiring purchase money received on the sale of government property to be paid into the Treasury. R. S. §§ 3617, 3618 (31 USCA §§ 484, 487 (Comp. St. §§ 6606, 6609)). While, in order to make the petroleum products available for the Navy, the Act deals with reserve lands as a separate class, there is nothing to indicate a legislative purpose to reverse the policy of conservation or to relax the safeguards as to fuel depots and contracts for their construction, set by prior legislation. The authority to 'store' or to 'exchange' does not empower the Secretary of the Navy to use the reserves to regulate or affect the price of oil in the Salt Creek field or to induce or aid construction of a pipe line to serve that territory. And it does not authorize the Secretary to locate the fuel stations provided for or to use the crude oil to pay for them. The Mammoth Oil Company insists that, even if other elements be held unauthorized, the transaction may be sustained as a lease granting the right to take the oil and gas in consideration of the development of the property and delivery of the royalty oils or the equivalent in cash. That view cannot prevail. The percentages of the product to be retained by the lessee includes the consideration, however indeterminate in amount, for the construction of the pipe line. Presumably, the lessee's undertaking to provide it induced the lessor to accept less than otherwise would have been asked or given. Cf. Hazelton v. Sheckels, 202 U. S. 71, 26 S. Ct. 567, 50 L. Ed. 939, 6 Ann. Cas. 217.

So far as concerns the power under the Act of June 4, 1920, to make them, the lease and agreement now before the court cannot be distinguished from those held to have been made without authority of law in Pan American Petroleum & Transport Co. v. United States, 273 U. S. 456, 47 S. Ct. 416, 71 L. Ed. 734; and the United States is entitled to have them canceled.

Were the lease and supplemental agreement fraudulently made?

The decisions below are in conflict, and we have considered the evidence to determine whether it establishes the charge. The complaint states that the lease and agreement were made as the result of a conspiracy by Fall and H. F. Sinclair to defraud the United States; that Fall acted for the United States and Sinclair acted for the Mammoth Oil Company; that the negotiations were secret, and the lease was made without competition; that responsible persons and corporations desiring to obtain leases were by Fall, in collusion with Sinclair, denied opportunity to become competitors of the Mammoth Company; that a company known as the Pioneer Oil Company asserted a mining claim to lands in the reserve; that the claim was worthless and known to be so by Fall; that he had Sinclair procure a quitclaim deed covering the valueless claim, and then, to make it impossible for others to compete with Sinclair's company, Fall made its transfer condition the granting of the lease; that Fall agreed with one Shaffer that Sinclair would cause a part of the leased lands to be set aside for the benefit of Shaffer, and required Sinclair, in order to get the lease for the Mammoth Company, to agree that Shaffer should have a sublease on some of the land; that, before and after the making of the lease, Fall kept the negotiations and execution secret from his associates, the Congress, and the public; and, in general terms, the complaint charges that Fall and Sinclair conspired to defraud the government by making the lease without authority and in violation of law and to favor and prefer the Mammoth Company over others.

As is usual in cases where conspiracy to defraud is involved, there is here no direct evidence of the corrupt arrangement. Neither of the alleged conspirators was called as a witness. The question is whether the disclosed circumstances prove the charge. When Fall became Secretary, Reserve No. 3 had already attracted the attention of oil operators. His predecessor, Secretary Payne, had arranged to offer highest bidders 15 lease in the Salt Creek field. These covered areas ranging from 160 to 640 acres, amounting in all to 6,400 acres. The royalties averaged 28.76 per cent. June 15, 1921, the leases were auctioned. Bonuses offered in excess of the specified royalties amounted in all to $1,687,000, and the leases were granted on that basis. That field was very productive. The reserve compared favorable with it, and was considered very attractive by all having knowledge of the structure. Obviously oil men would be interested in the opening of the reserve and the putting of its product on the market.

From the beginning Fall was keen to control the leasing of the naval petroleum reserves. Commander H. A. Stuart had been put in charge of naval reserve matters by Secretary Daniels; he continued as special aide to Denby, and was well qualified for that service. Early in April, 1921, Fall asked Assistant Secretary Edward C. Finney, who had long been in the Interior Department, to suggest some one who could handle naval reserve matters. Finney recommended, and Fall appointed, Dr. W. C. Mendenhall of the Geological Survey. Early in May, Fall had a memorandum prepared by Finney to disclose what power or authority in respect of the reserves could be delegated to Fall. Finney reported that the President might commit to the Secretary of the Interior the authorization of such additional wells or leases within the naval reserves as the President by section 18 of the Leasing Act (30 USCA § 227) was empowered to permit or grant; that under the Act of June 4, 1920, the Secretary of the Navy might request him to handle the conservation, development and operation of the naval reserves. And May 11, Fall sent Denby a letter inclosing for his approval a draft of a proposed executive order and a form of letter addressed to the President to be signed by Denby, requesting that the order be made. Fall said:

'Referring to our conversation yesterday, and to your suggestion to the President that the Secretary of the Interior be placed in charge of administration of the laws relating to naval reserves, I am submitting herewith for your consideration a brief memorandum stating the facts and law with respect to naval reserves, a tentative form of letter for your signature if it meets with your approval, and a form of executive order for the President's signature if it meets your suggestions of yesterday. * * * If they meet with your approval and no changes occur to you, kindly return them with your approval, in order that the matter may be taken up with the President.'

While this letter contains language calculated to indicate that Denby initiated the matter, the context and attending facts clearly show that Fall was eager to get the authority proposed to be given him.

Denby was not called as a witness, but the circumstances indicate that he intended to be passive and let Fall dominate. He sent Fall's form of executive order to Assistant Secretary Roosevelt and the Chief of the Bureau of Engineering, Admiral R. S. Griffin. After consideration of the matter by them and other officers of the navy, including Commanders Stuart, J. F. Shafroth, and E. A. Cobey, the Assistant Secretary told Denby that he thought that the property should not be turned over to the Interior Department. Denby replied that the matter had been decided by the President, Fall, and himself. Later the Assistant Secretary took to Denby a suggestion, prepared by him and his associates, for the amendment of the proposed order. Denby said: 'If you can get Fall to agree to this modification, then it will be all right with me.' Fall agreed to the change, and the President signed the form of order as amended. Its pertinent provisions follow:

'The administration and conservation of all oil and gas bearing lands in naval petroleum reserves * * * are hereby committed to the Secretary of the Interior subject to the supervision of the President, but no general policy as to drilling or reserving lands located in a naval reserve shall be changed or adopted except upon consultation and in co-operation with the Secretary or Acting Secretary of the Navy.'

We italicize words added as a result of the suggestion of Denby's subordinates. The executive order as signed by the President was what Fall wanted, and, so far as concerns the matters here involved, it was not substantially different from the draft he submitted to Denby.

Soon after the order was made, 22 offset wells in Reserve No. 1 were given to companies represented by E. L. Doheny and one McMurray, respectively. In connection with that matter, Fall had some trouble with Mendenhall and Stuart, and expressed himself as 'dissatisfied with both of them.' Thereafter neither of them was given anything to do in respect of reserve leases. July 8, 1921, Fall wrote Doheny a letter containing the following:

'There will be no possibility of any further conflict with navy officials and this Department, as I have notified Secretary Denby that I should conduct the matter of naval leases, under the direction of the President, without calling any of his force in consultation unless I conferred with himself personally upon a matter of policy. He understands the situation and that I shall handle matters exactly as I think best and will not consult with any officials of any bureau of his department, but only with himself, and such consultation will be confined strictly and entirely to matters of general policy.'

This exultant declaration that he was in position to handle these vast properties as he pleased discredits Fall. His desire to get control of the reserves and then so proclaim that he had it strongly suggests that he was willing to conspire against the public interest. And that inference is confirmed by his subsequent conduct.

By letter to Denby of July 23, Fall suggested the thought that royalty oil might be used to pay for fuel depots to be located and planned by the navy. That idea seems not to have originated in the navy. Such use of royalty oil was an essential element in any arrangement involving the prompt exhaustion of the reserves. It was the foundation of the scheme culminating in the lease. Denby, by letter to Fall of July 29, indicated his acquiescence. Soon thereafter Fall left Washington for the West, declaring that he was going to discuss the matter with oil men, 'with the idea of working up some such arrangement.' He returned about the middle of October. In the meantime Admiral John K. Robison was appointed to succeed Admiral Griffin as Chief of the Engineering Bureau. Denby directed Robison to take personal charge of all naval petroleum matters. Commander Stuart was relieved from all duties in reference to them. The record shows no reason for the removal of Stuart, but it does appear that Fall favored the change and that Denby knew it.

Immediately after he was given charge, Robison investigated and found that Reserves Nos. 1 and 2 were suffering loss from drainage and that Reserve No. 3 was not. He testified that he thought the latter pretty secure but not absolutely so. He read Fall's letter of July 23, suggesting the use of royalty oil to pay for storage tanks, and he made working arrangements with Fall, which were confirmed by a letter of October 25, prepared by Robison and signed by Denby and sent to Fall. They agreed that Fall was to control the making of all leases for the drilling of wells in the naval reserves and for the disposition of the products; that he would have necessary offset wells drilled in Reserves Nos. 1 and 2, but that the development of Reserve No. 3 would not be undertaken except to protect it against depletion by others; that the navy was to receive fuel oil for royalty oil; that so much of the royalty oil as was not exchanged for fuel oil would be used to obtain storage at places to be designated by the navy; and that the terms of the coversion should be submitted to the navy for approval as to qualities, deliveries, engineering, and other features involved.

Denby did not actively participate; but, in conferences with Fall, he was represented by Robison. Fall personally conducted the negotiations with Sinclair. And he contemporaneously arranged with Doheny the contract that was set aside for fraud in the Pan American Case, supra. Under the Secretary, Finney usually acted for the United States in making oil and gas leases, and he was authorized to sign them. But he was not consulted as to the terms of the naval reserve leases made to the Mammoth Company represented by Sinclair or to the Pan American Petroleum & Transport Company represented by Doheny, Robison through Fall undoubtedly exerted influence as to the provisions for the pipe line and fuel stations, but Fall acted for the United States and dominated in all matters substantially affecting the value of the lease. And it is significant that by the terms of the lease the Secretary of the Interior was authorized to permit the lessee temporarily to suspend production or to assign or terminate the lease.

November 30, at a meeting of the Secretary's Council, consisting of important officers in the navy, Robison advised, and it was decided, that the oil reserves should not be used to supply fuel oil for current use. He urged that leases be made and royalty oil exchanged for fuel oil and storage constructed by the lessees at places to be designated by the navy. Denby at first queried whether the exchange was authorized by law, and Robison called for the advice of the Judge Advocate General of the Navy. He answered affirmatively and, in the course of his opinion, said:

'The authority granted 'to exchange' is unrestricted; i. e., the act does not specify nor limit what may be taken in exchange for the oil and its products.'

Denby approved the opinion and authorized the proposed exchange. Robison prepared a letter, which Denby signed and sent to Fall, quoting the Judge Advocate General, and stating that Denby desired the Interior Department to make exchanges of crude oil for fuel oil and storage and that Robison had been designated to handle the details.

Then Fall went to his ranch at Three Rivers, N. M., where, December 31, came Sinclair and his counsel, J. W. Zevely, to see him, as the latter testified, on some business connected with Osage Indian leases. They remained two days. The showing as to what transpired concerning the Teapot Dome is meager. The record contains no statement from Fall or Sinclair. H. F. Bain, Director of the Bureau of Mines, was there for a day, but the leasing of the reserve was not mentioned in his hearing. Zevely testified that he was not sure whether the subject was mentioned in his presence, but he thought inquiry was made of Fall as to whether he would lease the Teapot Dome, and that Fall said he was having an investigation made, 'and upon that report he would probably determine whether or not he would lease' it. Nothing more is directly disclosed. But, soon after Fall and Sinclair met at the ranch, Fall caused his office force to investigate pending claims to land in the reserve and directed a report to be made to him on his return. Evidently he was considering leasing the reserve as a whole.

Fall reached Washington January 27, and, after conference with Robison, it was decided to develop all of Reserve No. 3. He sent for Sinclair and Zevely and had Robison tell them what would be necessary in any proposal for a lease. Robison told Sinclair that the whole reserve should be developed, that a pipe line adequate to serve the field should be constructed, and that royalty oil should be used to obtain fuel oil and to pay for storage facilities. And February 3, Sinclair wrote to Fall, stating that he was willing to take out all the oil in the reserve on a royalty basis and specifying features substantially the same as those suggested to him by Robison. He also proposed to quiet all outstanding claims and so enable the government to make one lease covering the whole reserve. His letter argued against granting leases by auction, asserted that the reserve was being drained, and insisted that it was better to have oil stored where needed than to keep the reserve underground. On receipt of the letter, Fall conferred with Sinclair and directed Arthur W. Ambrose, chief petroleum technologist of the Department, to give him an estimate of the quantity of oil in the reserve and 'some idea as to the possibilities of drainage.' February 18, Ambrose reported that he estimated 360,270,000 barrels in the Salt Creek field and 135,050,000 barrels in the reserve. His report disclosed no immediate danger of drainage but only a possibility of loss 'during the next six or seven years.' About that date Fall called Ambrose into his office where Sinclair and Zevely were, and, outlining certain provisions he wanted, directed that a draft of lease be prepared. The work of preparation required two or three weeks, and most of it was done in Zevely's office in Washington. Questions concerning its provisions arising from time to time were referred to Fall and Sinclair; they settled all the terms of the lease. The draft was not submitted to any lawyer in the Interior Department.

The Pioneer Oil & Refining Company and the Socie te Belgo-Americaine des Petroles du Wyoming had asserted placer mining claims to lands in the reserve. In 1917, the Department fully investigated and found these claims were without merit. In 1920, Secretary Payne held them invalid and denied application for a lease. In March, 1921, Assistant Secretary Finney dismissed claimants' petition for rehearing. Later they filed a petition to invoke the supervisory power of the Secretary. Answering an inquiry from Fall, Finney told him that the claims 'had no validity and no standing.' The last petition had not been heard when Fall and Sinclair met at the ranch. The report that Fall called for was ready before he returned to Washington; it stated that there were no claims deserving serious consideration. Obviously, Sinclair's proposal to quiet outstanding claims was the result of an understanding with Fall.

February 28, 1922, Sinclair caused the Mammoth Company to be organized. It promptly obtained from the Pioneer and Belgo Companies quitclaim deeds of all the reserve lands, and agreed with them that, in the event of obtaining a lease covering the lands, it would pay them $200,000 within 18 months and $800,000 more out of one-third of the value of the gross production less royalties. March 11, Sinclair wrote Fall submitting the Mammoth Company's formal application for a lease. He said that, if the lease were granted, he would become owner of all the capital stock of the company and would personally guarantee performance of the contract. He submitted a form of lease-presumably that already prepared in co-operation with Fall-all inclosed the company's quitclaim deed to the United States of all that was conveyed to it by the Pioneer and Belgo Companies. The record shows that, after he knew that the Mammoth had obtained these deeds, Fall told some who sought to lease the reserve that he would require the lessee to satisfy or clear up outstanding claims. In March, after much time had been spent in preparing the lease, Fall told a representative of a company seeking a lease that he was not ready at that time to consider leasing the reserve, and that, if he did so decide, he would notify the applicant. To one acting for another company, who called about April 10 to submit an offer for a lease, Fall indicated that he would entertain a bid, and said that he would be glad to see representatives of the company at Three Rivers. The lease had been signed by Fall April 7.

March 16, 1922, John C. Shaffer called on Fall concerning an earlier application for a lease covering a specified tract of 600 acres in the reserve. Fall said he was then negotiating with Sinclair for a lease covering the reserve. Shaffer insisted upon having some of it, and Fall said he had told Sinclair to set aside 200 acres for Shaffer. And when Shaffer demanded more, Fall advised him to see Sinclair, adding 'I think you will find him a very reasonable man, and you probably will make satisfactory arrangements with him.' Shaffer went to New York and saw Sinclair. The latter said that Fall had told him to reserve 200 acres for Shaffer. Shaffer demanded 600 acres, protracted negotiations between them followed, and it does not appear that any agreement was ever reached. Fall's arrangement with Sinclair for a sublease to Shaffer was extraordinary, and indicates that he had favored the Mammoth Company and that Sinclair on that account had assumed obligations not expressed in the lease.

About March 30 a rough draft of the lease was given Robison. April 7, Fall signed as Secretary of the Interior and 'for the Secretary of the Navy.' It was thought desirable, whether necessary or not, that Denby should sign, and, about April 12, he did so. Then Fall about to leave for New Mexico, told Finney that the lease had been executed, and locked it and copies in his desk. He said that 'he didn't want it to get out' until after the consummation of the contract (that set aside in the Pan American Case) for the construction of storage tanks, etc., at Pearl Harbor. He wrote Denby, inclosing a copy, and stating that delivery of the lease had been made to the lessee; that he had instructed his office force to give out nothing; that he was particularly anxious that no details should be disclosed pending the completion of the other contract. And, in order to support his refusal to furnish a Senator information concerning these contracts, Fall insisted that they should not be given out because military plans were involved. After Fall left, inquiries were made at the Department, but all information was withheld. When demand became more insistent, Fall wired his office to notify Sinclair to furnish a surety company bond, 'in view of congressional agitation,' instead of Sinclair's personal bond theretofore accepted. About April 21, information concerning the lease was given in response to a Senate resolution. There was never any legitimate reason for secrecy.

The Mammoth Company insists that the lease was made to protect the reserve from loss by drainage. The trial court did not pass upon the matter. The Circuit Court of Appeals found there was a remote but not immediate danger. It said (page 719):

'The drainage danger was unquestionably not imminent enough to force immediate action in the leasing of the entire property.'

That fact is satisfactorily established. A discussion of the evidence is not necessary. The circumstances, terms of the arrangement, and testimony of witnesses show that the lease and agreement were not made to prevent drainage. While the negotiations were pending, Fall and Sinclair indicated that they thought such danger existed, but the evidence warrants a finding that their expressions were made in bad faith to make it appear that there was a reason for the exhaustion of the reserve and the proposed disposition of its products.

In January, 1922, Fall was informed that counsel for certain oil companies had held that the use of royalty oil to pay for fuel depots was not authorized by law. He expressed fear that, because of the 'question as to the legality of bartering of royalty oil for storage, people would not bid for this contract and lease in California.' But he refused to submit the question to the Attorney General; and, as a reason for not taking such legal advice, said that 'the chances were at least even, or at least there was some chance' that an adverse opinion would be given, 'and, if the Attorney General signed such as opinion, * * * he (Fall) would be estopped from going anything.' And on April 12, the day that Denby signed the lease, Fall asked him to procure the adoption of an amendment to the pending naval appropriation bill, providing that storage for fuel oil from the reserves might be obtained by exchange of oil or by use of cash received for royalty oil sold. Fall sent Denby a draft of the amendment and undoubtedly thought its adoption would authorize the exchange of oil for the storage facilities contemplated by the lease. Under the circumstances, his failure to submit the lease to the Attorney General or to any lawyer in his own Department indicates that he knew that the transaction was liable to be condemned as illegal, and that, without regard to the law, he intended to put it through.

Shortly after the making of the lease, Fall received from a hidden source a large amount of Liberty Bonds, and others were used for his benefit. The substance of the disclosed circumstances follows. A. E. Humphreys controlled two oil-producing companies. H. M. Blackmer was chairman of the board of the Midwest Refining Company, a subsidiary of the Standard Oil Company of Indiana. The latter and the Sinclair Consolidated Oil Corporation owned share and share alike the Pipe Line Company and Purchasing Company. November 15, Humphreys, his counsel, Charles S. Thomas, Blackmer, Sinclair, and James E. O'Neit, president of the Prairie Oil & Gas Company, met in New York. It was there understood that Humphreys' companies would sell to Blackmer at $1.50 a barrel half their production up to 33,333,333 barrels, and also that they would sell at prices current in the field to the Prairie Company and the Purchasing Company half the production after delivery of the oil so sold to Blackmer. The same persons and R. W. Stewart, president of the Standard Oil Company of Indiana, met the next day. It was then understood that, instead of Blackmer, the Continental Trading Company, Limited, would be the purchaser in the first transaction, and that performance on its part would be guaranteed by the Prairie Company and the Purchasing Company. The papers were so drawn. On the same day, Henry Smith Osler, a barrister of Toronto, caused application to be made to the Secretary of State for Canada for the incorporation of the Continental Company. The next day he attended a meeting of the same persons and executed the contract on behalf of that company. Its performance was guaranteed as arranged, O'Neil acting for the Prairie Company and Sinclair and Stewart for the Purchasing Company. At the same time the Continental Company and these guarantors made a contract by which the latter bought all the oil so purchased by the Continental Company and assumed all its obligations. On the price basis specified, the gain of the Continental would be at least 25 cents per barrel and under some circumstances might be more. The Continental was to receive payments for the oil on the 10th of each month, but was not bound to pay the producers before the 15th. So it was assured profit of at least 25 cents per barrel without financing or effort of any kind. As permitted by Canada law, it issued share warrants to bearer with dividend coupons attached; except for qualifying shares, it put out no stock, did no other business, and kept no accounts. All its financial transactions were handled by the New York agency of the Dominion Bank of Canada. There was found no record disclosing who were financially interested in the company or entitled to dividends paid by it. Pursuant to Osler's instructions, the New York agency on April 13 and April 17, 1922, bought Liberty bonds of $300,000 par value; and, on May 8 following, Osler, as president of the Continental Company, gave the agency a receipt for Liberty bonds of that amount. There were other similar transactions; and, between February, 1922, and June, 1923, like purchases and deliveries amounted to more than $3,000,000. In May, 1923, the Continental Company assigned its contract with the Humphreys' companies to its guarantors for $400,000. Shortly afterwards, it was dissolved, and all its records were destroyed.

May 29, 1922, at Pueblo, Colo., Fall's son-in-law, M. T. Everhart, had $230,500 in Liberty bonds. Of that amount, $200,000 were, by the numbers thereon, conclusively shown to have been included in the lots purchased by the New York agency, April 13 and April 17, and receipted for by Osler May 8. Everhart gave the First National Bank of Pueblo bonds for $90,000 to be kept for Fall. He sold the balance to the M. D. Thatcher Estates Company at par and accrued interest. Fall and Everhart owned all the stock of the Tres Ritos Cattle & Land Company. The Thatcher Company had loaned the cattle company $10,000. Fall $15,000, and Everhart $83,000, and for security held all the stock of that company. Out of the proceeds of the bonds, Everhart paid these debts. The balance was distributed to the company, Fall, and Everhart. Out of the $90,000 in bonds given to the bank for Fall, $20,000 were deposited to the credit of the cattle company, and the rest was sent to Fall. In October and November, 1922, he sold $20,000 in Texas; and, in May, 1923, $50,000 in New Mexico. The government called Everhart as a witness; but, invoking the rule against compulsory self-incrimination, he declined to give any information as to where he got the bonds.

Humphreys and his counsel testified but were unable to disclose who were financially interested in the Continental Company. Blackmer and O'Neil went to France; and, on the application of the government, letters rogatory issued, but they refused to testify. Subpoena was issued for Stewart, but the marshal returned that he could not be found. Commissions were appointed to take the deposition of Osler in Canada. He was sworn but declined to disclose who caused him to organize the Continental Company or to give information as to its owners or the distribution of its assets. As ground for the refusal, he asserted that the information called for was privileged because communicated to or obtained by him in the course of his employment as a professional legal adviser, and that the company and its officers were his confidential agents for the better performance of his duties to his client. Application was made to the Supreme Court of Ontario to compel him to testify. That court held he must answer (56 O. L. R. 307); and its judgment was affirmed on appeal (56 O. L. R. 635). The District Court, on defendants' objections, refused to delay the trial pending final decision in the Canada courts, and thereafter refused to reopen the case in order to get Osler's testimony.

The creation of the Continental Company, the purchase and resale contracts enabling it to make more than $8,000,000 without capital, risk, or effort, the assignment of the contract to the resale purchasers for a small fraction of its probable value, and the purpose to conceal the disposition of its assets, make it plain that the company was created for some illegitimate purpose. And the clandestine and unexplained acquisition of these bonds by Fall confirms the belief, generated by other circumstances in the case, that he was a faithless public officer. There is nothing in the record that tends to mitigate the sinister significance attaching to that enrichment.

Fall ceased to be Secretary, March 4, 1923. Shortly afterwards, Sinclair gave him $25,000 under these circumstances. Sinclair, about to go to Russia on business, had Zevely arrange with Fall to meet him there. Fall was given $10,000 for expenses; and May 26, 1923, Sinclair directed his secretary, Wahlberg, to give Zevely bonds for $25,000 if the latter asked for them. A few days later, Zevely obtained the bonds, and, at Fall's request, had them sent to the First National Bank of El Paso. Zevely wrote the bank that the package belonged to Fall. By direction of Fall, the bank sold the bonds and gave him credit for the proceeds, $25,671.36. Zevely testified concerning the transaction before the Senate Committee on Public Lands, and that testimony was introduced at the trial by the defendants. Its substance was that Zevely went to New Mexico to see Fall because he did not want to write about the matter; that, in addition to the expense money, Fall wanted $25,000 to buy one or two small ranches there; that Zevely so reported to Sinclair, who said, 'If he does, you will have to let him have it;' that later Zevely had Wahlberg, who did not know the bonds were for Fall, send them to the designated bank; that the bonds were not given as a fee but as a loan from Sinclair; that, after Fall's return from Russia, he gave Zevely a note for $25,000 which the latter still held. Fall allowed the proceeds of the bonds to remain in the bank for a long time, and it does not appear that he ever bought the ranches. It is obvious that this was not a straightforward transaction. Coming so soon after the supplemental agreement made to perfect and carry out the scheme, it strengthens and confirms the inference that Fall had been willing to conspire to defraud the United States; and, taken in connection with other circumstances disclosed, it is persuasive evidence of such a conspiracy between him and Sinclair.

Familiar rules govern the consideration of the evidence. As said by Lord Mansfield in Blatch v. Archer (Cowper 63, 65):

'It is certainly a maxim that all evidence is to be weighed according to the proof which it was in the power of one side to have produced, and in the power of the other to have contradicted.'

The record shows that the government, notwithstanding the diligence reasonably to be expected, was unable to obtain the testimony of Blackmer, O'Neil, Stewart, Everhart, or Osler in respect of the transaction by which the Liberty bonds recently acquired by the Continental Company were given to and used for Fall. All the record contains nothing to indicate that the petitioners controlled any of them, or did anything to prevent the government from obtaining their testimony, or that they or the evidence they might have given was within petitioners' power. But the failure of Sinclair to testify stands on a different basis. Having introduced evidence which, uncontradicted and unexplained, was sufficient to sustain its charge, the United States was not required to call the principal representative of the company. His silence makes strongly against the company. It is as if he personally held the lease, were defendant, and failed to testify. The guiding considerations by which the proper significance of such silence is to be ascertained were well stated by Chief Justice Shaw in the celebrated case of Commonwealth v. Webster, 5 Cush. (Mass.) 295, 316 (52 Am. Dec. 711):

'Where, for instance, probable proof is brought of a state of facts tending to criminate the accused, the absence of evidence tending to a contrary conclusion is to be considered, though not alone entitled to much weight; because the burden of proof lies on the accuser to make out the whole case by substantive evidence. But, when pretty stringent proof of circumstances is produced, tending to support the charge, and it is apparent that the accused is so situated that he could offer evidence of all the facts and circumstances as they existed, and show, if such was the truth, that the suspicious circumstances can be accounted for consistently with his innocence, and he fails to offer such proof, the natural conclusion is that the proof, if produced, instead of rebutting, would tend to sustain the charge. But this is to be cautiously applied, and only in cases where it is manifest that proofs are in the power of the accused, not accessible to the prosecution.'

While Sinclar's failure to testify cannot properly be held to supply any fact not reasonably supported by the substantive evidence in the case (Northern R. Co. v. Page, 274 U. S. 65, 74, 47 S. Ct. 491, 71 L. Ed. 929), it justly may be inferred that he was not in position to combat or explain away any fact or circumstance so supported by evidence and material to the government's case. Runkle v. Burnham, 153 U. S. 216, 225, 14 S. Ct. 837, 38 L. Ed. 694; Kirby v. Tallmadge, 160 U. S. 379, 383, 16 S. Ct. 349, 40 L. Ed. 463; Bilokumsky v. Tod, 263 U. S. 149, 154, 44 S. Ct. 54, 68 L. Ed. 221; Vajtauer v. Commissioner of Immigration, 273 U. S. 103, 111, 47 S. Ct. 302, 71 L. Ed. 560; Clifton v. United States, 4 How. 242, 247, 11 L. Ed. 957; Missouri, K. & T. R. Co. v. Elliott (C. C. A.) 102 F. 96, 102. As to facts appearing to have been within the knowledge or power of Sinclair, we find that the evidence establishes all that it fairly and reasonably tends to prove.

The complaint did not allege bribery; and, in the view we take of the case, there is no occasion to consider, and we do not determine, whether Fall was bribed in respect of the lease or agreement. It was not necessary for the government to show that it suffered or was liable to suffer loss or disadvantage as a result of the lease or that Fall gained by or was financially concerned in the transaction. Pan American Case, supra, 273 U. S. 456, 47 S. Ct. 416, 71 L. Ed. 734. It requires no discussion to make it plain that the facts and circumstances above referred to require a finding that, pending the making of the lease and agreement, Fall and Sinclair, contrary to the government's policy for the conservation of oil reserves for the navy, and in disregard of law, conspired to procure for the Mammoth Company all the products of the reserve on the basis of exchange of royalty oil for construction work, fuel oil, etc.; that Fall so favored Sinclair and the making of the lease and agreement that it was not possible for him loyally or faithfully to serve the interests of the United States or impartially to consider the applications of others for leases in the reserve; and that the lease and agreement were made fraudulently by means of collusion and conspiracy between them.

The lease gave the Mammoth Company the right to construct tanks and other operating facilities on the reserve. In January, 1923, the petitioner, Sinclair Crude Oil Purchasing Company, bought from that company the tanks already constructed and others being built thereon. It used them to store Salt Creek royalty oil that it bought from the government. It claims that it relied on the validity of the lease and became the owner of the tanks as licensee and grantee of the lessee, and entitled to maintain them in all respects as the lessee was entitled to do under the lease. It contends that the Circuit Court of Appeals erred in directing it to be restrained from further trespassing upon the reserve, and that in any event it should be given opportunity to remove its property. But the Purchasing Company is presumed to have known that no law authorized the making of any such lease. The existence of that arrangement for the exhaustion of the reserve was calculated to excite the apprehensions of one considering such a purchase and put him on his guard rather than to give assurance of safety. The use of such tanks to take oil from the reserve was a part of the illegal scheme. Moreover, the Purchasing Company was owned half and half by the Sinclair Consolidated Oil Corporation and the Standard Oil Company of Indiana. Sinclair was chairman of the board of the former, and Stewart held like position in the latter. Shortly before the Purchasing Company bought the tanks, these chairmen acted for and controlled it in respect of most important transactions. That and other disclosed circumstances are sufficient to impute to it Sinclair's knowledge of the conspiracy to defraud by which the lease was obtained. It is clear that, in respect of the use and removal of these tanks, the Purchasing Company is in no better position than the Mammoth Company would have occupied, if it owned them.

The Sinclair Pipe Line Company, as lessee's nominee to build the pipe line provided for in the lease, expended a large amount in constructing on the reserve a pumping station, pipe line and other equipment necessary for the transportation of the oil therefrom. It asserts that it relied on the validity of the lease, had no knowledge of any fraud in its procurement, and made these expenditures in good faith. It contends that it should have opportunity to procure from governmental authorities a right to use the reserve lands for the operation of the pipe line and equipment thereon; and, failing to get a right of way or easement for that purpose, it should be allowed to remove its property. That company was also owned half and half by the Consolidated Company and the Standard Company. It was a mere nominee to do some of the work specified in the lease to be performed by the lessee. It is chargeable with notice that the use of reserve oil to procure the construction of the pipe line was a part of the plan for the unauthorized exhaustion of the reserve; that such use furthered the violation of law and was contrary to the established conservation policy. The Pipe Line Company stands on no better ground than the lessee would have occupied if it had made the improvements in question.

The tanks, pipe line, and other improvements put upon the reserve for the purpose of taking away its products were not authorized by Congress. The lease and supplemental agreement were fraudulently made to circumvent the law and to defeat public policy. No equity arises in favor of the lessee or the other petitioners to prevent or condition the granting of the relief directed by the Circuit Court of Appeals. Petitioners are bound to restore title and possession of the reserve to the United States, and must abide the judgment of Congress as to the use or removal of the improvements or other relief claimed by them.
