delivered the opinion .of the court.
The plaintiff allegés, that he is the owner of an exclusive privilege or right of ferry across the Mississippi river, from the place known as the post of Concordia, in that parish, to the City Of Natchez. That his exclusive privilege extends one league above and below the point or place named in his grant* which is the front of a tract of land of eight ‘arpents on the river, granted to Thomas Thompson, to whom this exclusive privilege was also granted, as one annexed to the land; by the Governor General of Spain in the province of Louisiana. This grant, he says, was made on the condition, that Thompson should clear a public road Or highway from the said Post of Concordia to the Bayou Crocodile, which condition he specially alleges has been performed.
He further states, that the Police Jury of the parish have passed an ordinance directing the parish treasurer to sell at public or private sale, the exclusive privilege of keeping a ferry for a certain length of time across the áforesáid river at the same place, where his (plaintiff’s) ferry crosses, which will he a great injury to him ; that said parish treasurer is about to proceed to make a sale of said privilege; and will do so, unless *538restrained by law. He prayed for damages and an injunction ^ arrest the execution of the ordinance.
The defendants admit the passing the ordinance, say it was legal and valid, and avow their intention to have it executed unless prevented. They deny any exclusive privilege of keeping a ferry was ever granted by competent authority to Thompson, and if any ever was, they say it is null and void, because the terms and conditions have not been complied with or performed by the grantee or those holding under him ; and that it has been forfeited by non-user. That by the interference of the plaintiff with their just rights, they have sustained heavy losses ; they ask for a dissolution of the injunction and one thousand dollars damages.
The cause was tried by a jury ; there was a “ verdict for defendants with Í400 damages,” on which the court rendered judgment, dissolving the injunction, and decreed the plaintiff 'to pay the four hundred dollars, from which he appealed.
The plaintiff produced as evidence the petition of Thomas Thompson, addressed to the Commandant of the Post of Con-cordia, representing the importance of having a road from that place to the Bayou Crocodile, and the inability of the inhabitants to make it, without their expenses being paid by the government; he therefore proposes to make a road thirty or forty feet in width, provided the privilege of a ferry from his plantation to the landing at Natchez is granted him, this privilege to be attached to the plantation. He promises, if the ferry is granted, to keep the necessary flats and boats to transport passengers, &c. The commandant Don José Vidal certifies to the governor, at the foot of the petition, the importance of- the work, the inability of the inhabitants to perform it, the ability of Thompson to do what he promises, and recommends the propriety of the grant. These documents were presented to the Marquis de Casa Calvo, who on the 19th of February, 1801, says, that if the petitioner shall make the road he proposes, under the inspection of the commandant, he grants him •the privilege he asks, to be attached to his plantaiion ; that from *539lhat place he shall have the exclusive privilege of a ferry across the river, demanding- and receiving such tolls as shall he fixed' by the commandant. It is proper to observe here, that the Marquis de Casa Calvo does not take upon himself any official capacity in this act, and the history of the province of Louisiana is silent as to his ever haying been governor, unless he acted as such, ex officio during the period between the death of governor Gayoso, which occurred in the summer of 1799, and the arrival of Salcedo, who was appointed military and political governor on the 2.1st of November, 1799; or in the absence of the latter on some occasion.
On the 16th of February, 1802, Don José Vidal, the commandant, certified, that the condition specified in the memorial had, been performed under his inspection, and that Thompson was vested with the exclusive privilege granted. On the 13th of- September, 1803, Thompson conveys the tract of land, without saying anything about the ferry, to Don José Vidal, in consideration of the sum of $4000 paid down, and on the 16th of October following he transfers in writing on the back of the paper purporting to grant, to the same person, all the right, title, claim and interest to the privilege granted, having, as he-says, sold to him the plantation, to which the said right of ferry is annexed.
This tract of land, with the right of ferry attached, and another tract adjoining, Vidal in 1817 sold to the plaintiff, who has ever since kept up a ferry, but had the landing place on the adjoining or Vidal tra.ct, as his immediate vendor seems also to have had.
A great deal of testimony was taken on both sides to show, Thompson had or had not used the grant, and that Vidal- and Davis, his assignees, had never used it from the front of the Thompson tract, but from a point a quarter to a half mile above. Each party endeavored to exclude as much of-the testimony of his opponent as possible, and both have so far succeeded as to bring the case before us in. a very unsatisfactory manner, and. *540in Such, a situation as prevents us from doing justice between as stan(Js.
On. the trial the plaintiff, having proved,-that there had always been a ferry kept by him and Vidal, on a tract of land -|jei0I1gjng t0 them, adjoining to the Thompson tjact, offered to prove the public convenience was promoted by the ferry being kept at that point, which evidence the judge refused to admit, and plaintiff excepted. We think the judge erred. The evidence ought to have been admitted, and the effect of it after-wards considered. We think the judge also erred in excluding the evidence offered by plaintiff, to show that the Thompson tract of land was not worth at the time it was sold $4000, without the right of ferry. It ought to have been received, and the effect weighed with other circumstances.
We further think the judge erred, in excluding the evidence offered by defendants, to prove Thomas Thompson never did make the road from the river to the Bayou Crocodile, as stated in the certificate of the commandant. The making of that road was the consideration for the grant; the plaintiff in his petition tendered the defendants an issue on that point, in which they joined by a special denial. The plaintiff was permitted to show by the commandant’s certificate the condition was performed, and the district judge was wrong in holding it to be conclusive. We think it only prima facie evidence, which the defendants may contradict. The commandant did not act in the matter in any judicial capacity, he was only a commissioner or superintendant, tq see a particular work was executed ; and no more sanctity is to be attached to his certificate, than to -presume he did his duty, and told the truth; and thereby throw the burden of proving a negative on the other party.
We think the judge also erred in excluding the documents I, J, K and L offered by the defendants, to prove that, although the plaintiff had kept a ferry at the place he did, it was under the supervision and control of the Police Jury, The evidence was clearly admissible, to show an interruption or want o.f the prescriptive right set up by plaintiff.
*541The judge did not err in admitting in evidence the record books from the parish judge’s office, to prove the recording of the acts therein contained, nor did he err in permitting a person, who on oath said he understood the Spanish language, to read and translate those records to him and the jury, they not understanding that language.
We further think, the judge did not err in admitting in evidence the instrument purporting to be the petition of Thomas Thompson, and the recommendation by Vidal as commandant, and the grant signed by the Marquis de Casa Calvo, without proof of the signatures. They ar e prima facie evidence. That Vidal was the Commandant of the Post of Concordia at the time, is a matter of history; that Casa Calvo was about that time an officer of high authority in a military capacity, is also known; and it is possible .he may have exercised some civil function, as was frequently the case under the Spanish government ; but we do not believe he ever had a commission as Governor of the province of Louisiana. Salcedo, we have stated, was appointed military and political governor in November, 1799, and he continued to be such at the time Spain transferred the province to France, on the 30th of November, 1803, on which occasion he and Casa Calvo acted as the commissioners of the King of Spain, to deliver the country. Casa Calvo then was styled a brigadier in the King’s armies, &c. 2 Vol. Land Laws, Appendix I, p. 165; Idem, p. 529. This evidence being prima facie, the defendants are at liberty to contradict it, and may show, that the Marquis de Casa Calvo was not governor or acting as such at the time of the grant. But until some sufficient evidence is given to the contrary, we will presume an authority existed. 12 Peters, 410.
We think the judge did not err in admitting the transfer of the privilege or grant by Thompson to Vidal, to be proved by comparison, after the signature of Minor, the subscribing witness, was proved, and it was shown he was dead. Had. these facts not been shown, we think the comparison ought to have been made with more than one authentic or admitted signature. *542O. C. C., p. 306, art. 226; L. C., art. 2241; 2 M.

The judgment of the District Court is therefore annulled. avoided and reversed, the verdict of the jury set aside, and it is further ordered, that this case be remanded to the District. Court, with directions to the judge to conform, in the admission or rejection of testimony to the principles herein express», ed, and otherwise to proceed according to law, the defendants, and appellees paying the costs of this appeal..
