THIS was an appeal from the District Court of the United States for the District of Arkansas.

It was a petition filed by the heirs of Don Carlos de Vilemont, under the act of 1824, as revived by the act of 1844, praying the confirmation of a grant of land issued by the Baron de Carondelet in 1795.

The circumstances attending the grant are set forth in the opinion of the court.

The District Court decided against the claim and the petitioners appealed to this court.

In the District Court, Horace F. Walworth, Mary B. Miles, and James B. Miles, were made defendants with the United States.

It was argued in this court by Mr. Taylor, for the appellants, and Mr. Lawrence and Mr. Crittenden, (Attorney-General,) for the appellees. A brief was also filed by Mr. Pike for Mr. Walworth.

Mr. Taylor, for the appellants, thus noticed the omission of Vilemont to comply with the conditions of the grant. (It will be seen, by referring to the opinion of the court, that this was an important point in the case.)

The confirmation of the claim is resisted in the answer of the District Attorney, on the ground that the conditions of the grant were not complied with. The conditions, as has already been stated, were those almost invariably inserted in orders of survey, that a road and a settlement should be made within a given day. The record contains the testimony of two aged inhabitants of Louisians, who, as officers in the same regiment in which Vilemont served many years, were attached to the person of the Governor, and one of whom was employed in the Land-Office in New Orleans, showing that these conditions were mere matters of form and mechanically inserted with the orders of survey, without inquiring into the situation of the land. They add that they never were enforced, and that no land was ever forfeited under the Spanish government on account of a non-compliance with these conditions. This testimony is emphatically confirmed by Judge Simon, for many years a practising lawyer in Louisiana, and during six years a judge of the Supreme Court of that State, before whose eyes probably thousands of such claims have passed.

In this instance the land was asked for to establish a stock farm. What necessity was there to cultivate it, if such was the purpose of the grant? And how much of the two leagues front and one in depth should have been cultivated and established? The land was twenty-five leagues below the mouth of the Arkansas, and more than that distance from any white settlement. What use would there have been for a road, and where would it have been?

But if these conditions, in such a case, were more than an idle formality, Vilemont would have been relieved from a compliance with them. In 1795, when the grant was made, and until 1802, Vilemont was the civil and military commandant of the post of Arkansas. During all this period he never left his post, not even to visit New Orleans. His presence there was constantly required by the threatening aspect of the Indian tribes by whom he was surrounded, while the garrison of the fort never exceeded forty men. Eight letters from Governor Carondelet to Vilemont, (which will be found on pp. 72-76 of the printed and Vilemont's official correspondence with the Governor of Louisiana, until his appointment to a higher office, in 1802,) furnish a striking proof of the arduous service in which he was engaged, and of ceaseless feuds among the Indians, and attacks upon the whites, and leave no doubt that even a temporary absence from the command would not have been tolerated by the Governor. Can it be pretended that, under these circumstances, the government seriously, and under paid of forfeiture, expected him to make a road within one year, and a settlement within three years, upon this rude and remote spot? The government kept him until 1802 at the post of Arkansas; the government then removed him to a new scene of service, and this, if any case, falls under the rule established in the United States v. Arredondo et al., 6 Pet. 745. 'It is an acknowledged fact that if a grant is made on a condition subsequent, and its performance becomes impossible by the act of the grantor, the grant becomes single.'

The other reason why a settlement could not be required of Vilemont is, that hostile Indians made it impossible. Vilemont was not bound, though he might have attempted, to form a settlement by agents. Indeed, already, in 1795 or 1796, he sent Bogy there with that object, but Bogy was driven off by the Indians. Nor did the danger from the Indians cease until a number of years after the change of government.

Mr. Crittenden, for the United States, made the following points:

I. That the appeal ought to be dismissed for want of being duly prosecuted.

II. That the appellants' ancestor was never put in possession of the lands, and the conditions on which the concession was made were not performed during the time therein limited, or during the sovereignty of Spain over the country, or subsequently.

There is no evidence whatever that the Surveyor-General, or a deputy approved by him, ever put Vilemont into possession of the lands as required by the terms of the concession. No survey was ever made, and no plat and certificate were ever reported to the governor, and no title in form could therefore have been issued to Vilemont at any time during the continuance of the Spanish power.

The petition of de Vilemont sets forth his desire to establish a plantation and stock farm, in order to supply the post, of which he was commandant, with cattle. This is the inducement he presents to de Carondelet to make the concession. It was accordingly made to him under the express condition that he shall make the regular road and clearing within the peremptory* term of one year, the concession to be null, if, at the precise expiration of three years, the land should not be established.

From the date of the grant, in 1795, until the delivery of Louisiana to the United States, in 1803, he had completely failed to comply with the conditions above mentioned, and thereby forfeited all right to require a title in form. He had done nothing whatever. This, therefore, is not such a concession as might have been perfected into a complete title had not the sovereignty of the country been transferred to the United States.

But to examine the evidence on the point of non-performance of the conditions presented in the record:

The appellants themselves state, in their petition, that De Vilemont 'endeavored, soon after the date of said concession, to procure persons to make a settlement, but could not succeed' on account of the danger arising from hostile Indians. It further states, 'that in the year 1803 he again attempted a settlement, but that, from the year 1807,' he, or persons employed by him or his family, had been in actual possession of part of the land.

The above is the petitioners' own statement. In 1813, in De Vilemont's lifetime, when he presented his claim to the recorder of land titles, he did not submit a particle of proof to show that he had done any thing with respect to establishing the stock farm, making the road, or settling the land. Joseph Bogy, his father-in-law, then testified that he, De Vilemont, proposed to witness to settle on the tract, but that he declined on account of the supposed danger from the Indians, which continued until 1803. Francis de Vaugene also then testified that the Indians continued so hostile as to make it unsafe to settle at Isle Chicot till the year 1803.

It will thus be seen that De Vilemont made no pretence then, or offered no proof to show, that he had fulfilled any of the conditions, but he sets up an excuse merely for not having done so. The recorder, under the column titled 'possession, inhabitation, or cultivation,' states, 'danger from the Indians prevented settlement,' and gives his opinion that the claim ought not to be confirmed, the conditions not having been complied with.

Mr. Crittenden then examined the evidence.

But it is said that De Vilemont could not leave his post to attend to the performance of the conditions, that he was prevented from performance by danger from the Indians, and that the conditions were merely formal.

The answers to the first of these excuses are obvious. De Vilemont styles himself, in the petition to Baron de Carondelet, the commandant of the post of Arkansas, and asks for the land at the place it is given, the inducement being, that he might furnish cattle to the post. It would be strange if, under these circumstances, his not being allowed to leave the post should excuse the performance of the conditions. As to being prevented from establishing the stock farm, and performing the other conditions, by danger from the Indians, he knew that the Indians were in the country at the time he made the application; and if he sought for a concession, the conditions of which he could not comply with, it can afford no exemption from their performance. As to the allegation that the conditions were merely formal, it is negatived by the third article of O'Reilly's regulation, where the non-performance of the conditions as to roads, settlements, &c., is thus spoken of: 'And in default of fulfilling these conditions, their land shall revert to the king's domain, and be granted anew.' 2 White's Recop. 228. These regulations were approved by the king. See letter of Marquis de Grimaldi to Unzaga, 24th August, 1770, Id. 460. See also the third, fourth, fifth, and sixth articles of regulations of Morales, Id. 235.

III. That the evidence in the case shows that De Vilemont had abandoned his claim to the land.

IV. That the concession is void, because no land was severed from the public domain by survey giving it a certain location, previous to the treaty of cession, and the description is so vague, indefinite, and uncertain, that no location can be given to the lands. United States v. Miranda, 16 Pet. 156; United States v. Boisdor e, 11 How. 63.

V. That the decree as to floats is void, the individuals holding the lands in respect of which floats are decreed, not having been made parties in the case.

Mr. Justice CATRON delivered the opinion of the court.
