This is an ejectment brought by John , , and George Rance, against Joseph and John Salmon, for 150 acres of land, part of a tract containing upwards of 400 acres surveyed for Thomas Christie in October, 1785. The record exhibits a large mass of parol evidence, on which the Court below delivered a charge which is complained of by the Salmons, plaintiffs in error. The case which the plaintiffs below endeavoured to mate out, was in substance as follows: For some time previous to the year 1800, the plaintiffs had been in possession of part of the above-mentioned tract, claiming under an improvement made by a certain Melchior Heflick. But, although in possession, they were apprehensive that their title was not good, the land having been appropriated by another person under a warrant and survey, before the commencement of the improvement, in the year 1800, the plaintiffs were informed by Joseph Salmon,.that an opportunity would soon be offered, of securing a good title to the whole tract of land; that the title was in Robert Morris, against whom Richard Salmon, (cousin of Joseph,) had *312obtained a judgment for upwards of 1500 dollars, on which a testatum fieri facias had been issued, and levied on the sajcj tract, which was shortly to be sold by virtue of a writ of venditioni exponas ; that if the plaintiffs would pay 27 dollars an acre, the whole tract should be secured to them by a deed from the sheriff of Northumberland county, which would give them a good title. The defendants agreed to give 27 dollars an acre, atad paid to Richard Salmon, 951. 7s. 6d. in property of various kinds, including two notes, one for 91. and'the other 11/.; and besides this, Andrew Ranee, father of the defendants, gave two bonds of his own, for 75/. each. The land was put up to sale by sheriff Irwin, and struck off to John Ranee, for 185/. No part of this 185/. was ever paid, neither did the sheriff execute a deed of conveyance, or make .return of the writ of venditioni exponas. No evidence was given of the payment of Andrew Ranee’s bonds. The plaintiffs contended, that some part of the money paid by them, went into the hands of Joseph Salmón; and that in fact, Richard and Joseph Salmon, well knowing, that Robert Morras had no title, had combined and confederated in a plan to defraud them, after which Joseph purchased the true title from Philip Schrceder, and obtained the possession. This, I say, is the substance of the case, which the plaintiffs contended, they had made' out by their evidence. On the other hand, the defendants denied, that there was any intent to defraud or deceive; and asserted, that Richard and Josepk Salmon, really thought, that Robert Morris’s title was good; that Joseph was no way concerned in point of interest, nor eVer received, for his own use, any part of the money paid by the plaintiffs ; that the two bonds of Andrew Ranee were not paid; and that the plaintiffs, instead of going on to pay 27 dollars an acre, for the whole tract, had paid no more than 95/. 7s. 6d. as before stated, after which they stood upon their improvement title, and declined taking a title from the sheriff, under the execution against Morris. Whether the plaintiffs or defendants were right in their conclusions drawn from the evidence, it is not for us to say, nor do I intimate any opinion on that subject. The question is, whether the Court below were right in their charge to the jury, which is now to be considered. The charge was, that if the jury should be of opinion, that Joseph Salmon encouraged the plaintiffs to purchase at the sheriff’s sale, and asserted, that Morris had *313a good title, and especially, if Joseph Salmon was interested in the transaction, and received part of the money paid by the plaintiffs, in such case, the title obtained by Joseph Salmon, from Schrceder, would enure to the use of the plaintiffs, and the verdict ought to be in their favour. It appears to me, that this charge was more favourable to the plaintiffs than the law will warrant. The legal title was in the defendants, from whom the plaintiffs demanded equity. What then was the equity of the case ? The plaintiffs had engaged to pay 20 shillings an acre to Richard Salmon, which would have amounted to about 424i. for the whole tract; of this, there was no evidence, that more than 9Si. 7s. 6d. was paid, nor had they made any offer of the residue. There could be no equity, in forcing the legal title from the defendants, without paying the balance of principal and interest. But, sav the plaintiffs, we ask no more than 150 acres. The answer is, that the engagement was, according to the plaintiffs own pretentions, to take the tv hole, and pay for the whole ; and unless the whole is paid, Richard Salmon loses the greatest part of Robert Morris's debt. But why is it that the plaintiffs only demand 150 acres ? The answer to this question, leads to an important consideration, which ought to have been submitted to the jury. The defendants say, that on this tract of land, were several persons settled, claiming under improvement rights ; that these persons were suffered to remain unmolested by the plaintiffs; and that in truth, the plaintiffs chose rather to share the land -with these settlers, than go on to complete the purchase from sheriff Irwin. The jury ought to have been told, that if the plaintiffs declined to carry into effect the whole agreement made with Richard Salmon, this would amount to a disaffirmance of the contract, in which case, the most that they could be entitled to, would be a reimbursement of what they had paid, with interest; but they would not be entitled to recover the land from Joseph Salmon. But, whatever might be the opinion of the jury on that point, the plaintiffs have not done enough to entitle them to a recovery in this ejectment; because they have not paid, or tendered, what, according to their own story, they had agreed to pay. I am, therefore, of opinion, that there was error in the charge of the Court. But, besides the exception to the charge, there were five bills of exceptions taken by the defendants on matters of evi*314dence. 1. The first exception was to a private memorandum book, or docket of sheriff Irwin, in which was an entry, that this tract of land, containing 424 acres, was struck off to Mr. Ranee, for 185/. This book was admitted in evidence, and in my opinion, improperly. If the land was sold by the sheriff, the best evidence would be, his return to the venditioni exponas. ■ But even, if it were material to the plaintiffs’ case, to shew, that the land was struck off to Ranee, the proper evidence would have been, the oath of some person present at the sale. There could be no difficulty in procuring evidence of what passed at a public sale. The general rule is, that evidence shall be on oath. These entries in the sheriff’s book, were not on oath ;■ no body was responsible for the truth of them. The law knows nothing of the sheriff’s private entries, and pays no regard to them. The book, therefore, ought not to have been received as evidence.

2. The evidence of Peter While, when he was called a second time, by the plaintiffs, was objected to ; not because the witness was incompetent, or the-matter irrelevant, but because, the defendant supposes, the testimony given by him then, was out of place, and ought to have, been reserved as rebutting evidence. Perhaps it might have been very properly reserved; but this is not a point on which a judgment should be reversed. 'The plaintiff may, if he pleases, with the Court’s permission, anticipate the defendants’ case, and defeat it. The Court, in their discretion, will regulate the order in which the evidence shall' be given. But, for a Court of error, to enter minutely into matters of that kind, would be, to intrench, unnecessarily, on the right of the Court below, and to embarrass the administration of justice, instead of assisting it. I think there is nothing in this exception.

3. The third exception is to the admission of Frederick Ranee, as a witness. He was alleged by the defendant to be incompetent, because he had been security for the plaintiffs, on their appeal from the report of the arbitrators in this cause. To remove this objection, the Court discharged him from his recognisance, and took other security in his stead. I do not see why the Court of Common Pleas might not do this. It is a common practice to strike out bail and take new bail, for the purpose of making a witness. This is not exactly the striking out of bail, but it falls within the reason of it. The security, in the first instance, was taken by the Court’s *315own officer, (the prothonotary,) and the new security being taken under their own inspection, no harm can be done to the defendant, for whose use the security was given. I am, therefore, of opinion, that F. Rance was a good witness.

4. The fourth exception was to the admission of John Keller, as a witness, on the ground of incompetency. Keller had sold and conveyed to William Marr, his title, under an improvement right, to part of this land, for which Marr had given him his bond for 85/. As to the land, Keller had parted with it, without warranty, so that it was out of the question. But he had also given to Marr, a covenant of warranty of the land, in case Rance should recover it. This could be no objection to his evidence, because, in swearing to establish Rance's title, he swore against his own interest. He was, therefore,'a competent witness.

5. The fifth and last exception was to the rejection of a memorandum, in writing, made by Thomas Woodside (deputy surveyor,) at the foot of a return of the survey of the tract of land in question, made by the said Woodside, in the year 1812. The memorandum is as follows. “ N. B. The “ survey above stated, was regularly surveyed to Thomas “ Christie, but, by mistake, the return appears to have been “made, on the ground on which Preserved Cooley was sur- « veyed; the original drafts have Thomas Christie marked “ on the survey above stated.”

The deputy surveyor is a sworn officer, and his return to an order of survey is evidence, because the law supposes, that an officer has done his duty. But when he goes beyond the line of his duty, his work is not evidence, especially when he undertakes to say, what may be proved by better evidence. Now here, besides making the return of survey, he tells of a mistake made many years before, by another person; a fact, of which he could have no certain knowledge ; he speaks also, of an indorsement on^ an oficial paper, which must appear on the paper itself, and therefore, nothing but the paper itself would be evidence. In fact, Mr. Woodside himself was examined as a witness in the cause, and his testimony on oath as to the matter of this nota bene, was better evidence than the nota bene itself, which was without oath. It appears to me, therefore, that the Court did right in rejecting this evidence.

Upon the whole, I am of opinion that the judgment should be reversed,.and a venire facias de novo awarded.

Upon the facts, it is very clear, the plaintiffs could not recover on their improvement right; for when Hejlick began his settlement, the land was not vacant, and. the Court before whom the cause was tried, did right to instruct the jury to that effect. Neither could they claim under Morris, for his title, if he had any, (which does not appear) was not conveyed to them. It, therefore, became necessary for them to rest their cause upon their purchase from Richard Salmon, and to shew, that they were induced to take a defective title by the fraudulent misrepresentations of Joseph Salmon. I have no hesitation in saying, that a person confederating with a vendor, and by fraudulent misrepresentations, inducing a vendee to purchase a defective title, and to pay a valuable consideration for it, will, in equity, be considered as standing exactly in the same situation as the vendor himself, as regards a title acquired by him after-wards. If a person, having a right to an estate, permit or encourage a purchaser to buy, the purchaser shall hold. Sugden, 480. In point of principle, I can see no difference between an existing right, and one acquired afterwards. In Montifiori v. Mantifiori, 1 W. Bl. Rep. 363, it is laid down, that as against the party guilty of the fraudulent misrepresentation, the thing shall be as represented to be. If, then, by the fraud of Joseph Salmon, the plaintiffs had been induced to purchase and pay for Morris's title, as being good against all the world, the former would be estopped from setting up' his after acquired title, or averring to be the contrary of what he represented as the fact. He would stand precisely in the situation of Richard Salmon, who, in case he had acquired the title under Christie's warrant and survey, would' have been a trustee for the plaintiffs, whom a chancellor would compel to convey. I take every misrepresentation to be fraudulent, where the party making it, positively asserts a fact to be true, which he does not know to be so, and which turns out to be untrue. To a party having a right to information, and who suffers damage from reposing confidence in such assertion, it amounts to a warranty of the truth of the fact. But it would be different if a person should merely state his belief, and disclose the reasons on which he founded it. The party receiving the information would then judge for himself. Now, it appears from the evidence, that the purchase from Richard *317Salmon, was brought about, by the instrumentality of Joseph Salmon. He brought the parties together, averred that' Morris had a good title, that it had been exhibited to him, and proposed the terms of the purchase, and the mode of vesting the title. If, then, the plaintiffs had complied with their part of the contract, there can be no question, but they would be entitled to recover. But in this particular, their case is totally deficient, and in this point of view, the Court below erred, in not leaving it to the jury. The purchase money, at the rate of twenty shillings the acre, amounted to 424i. Of this sum, not more than 9Si. 7s. 6d. was actually paid. Two bonds of 7Si. each, were given by the father of the plaintiffs; but it does not appear, that their contents and the balance of the purchase money was ever paid, or tendered; which I hold indispensable to the plaintiffs recovery. But it is contended, that having paid a part of the consideration, they can recover pro tanto. To this I cannot assent. They can only recover by affirming the purchase from Richard Salmon, which is the foundation of their title. It is this contract that would, under certain circumstances, draw after it the equitable interest in the title, afterwards acquired by Joseph Salmon. It cannot be affirmed in part, and disaffirmed in part. It would be a most unreasonable advantage to permit them to complete their agreement up to a certain point, there stop, and recover in proportion. That would be to make a new contract between the parties, totally different from the original agreement.

2. The admission of the memorandum of the sale to the plaintiffs, found on the docket of sheriff Irwin, was indisputably an error. The venditioni exponas, by virtue of which this sale was made, having never been returned, the sale, if evidence at all, was a matter in pais, to be proved like any other fact. I cannot conceive on what ground this private memorandum could be supposed evidence. The fact was susceptible of higher proof from the testimony of by-standers; and I apprehend that even a book of original entries would not be evidence to prove the sale of even personal property, against a third person, for the vendor might be called.

3. Keller, who was objected to as interested, was not so in point of fact. It is true, that in his deed to Marr,' there was an agreement that he should have a further sum in case *318the plaintiffs succeed in establishing their title. This interest, such as it is, was parted with before he was offered as a witness, and, at all events, it does-not appear the plaintiffs were privy to the engagements between him and Marr, without which they could not be divested of the interest they had in his testimony. But, in truth, his interest is, that the plaintiffs should not recover; for he then would have been relieved from his engagment to warrant the title he conveyed to Marr. He was, therefore, properly admitted.

4. I also think Frederick Ranee was properly admitted. The power of the Court to substitute bail, for the purpose of making a witness competent, is undoubted. It is a discretionary power, in the exercise of which, care will, however, be taken, that no prejudice happen to the party secured. The person offered as a substitute, ought to be clearly and indisputably unexceptionable in every view. With this restriction, it should be liberally exercised, for the attainment ■of truth, between the parties. In the present case, there are no peculiar circumstances to distinguish it from any other.

5. It is objected, that the certificate attached to the return of survey on Christie’s warrant, made by Thomas Woodside, •should have been received as evidence. This certificate sets forth n® fact, occurring in, or connected with, the execution, of the official duty of the surveyor; but a mere inference of a fact, from documents remaining in his office. These documents, then, ought to have been produced, being the best evidence of which the case was susceptible. The certificate was secondary, and properly rejected.

Judgment reversed, and a venire facias de novo awarded.
