¶1This was an action on the case commenced in Rush county by Phebe Ann Shelton, by her next friend, Benjamin C. Plummer, against Charles Conaway, to recover damages for the breach of a promise of marriage.
¶2*335Pleas, the general issue, and a plea that the defendant, at the time of making said promise, was an infant. Replication to the plea of infancy, that the defendant ratified said promise after arriving at majority. Rejoinder, that the defendant did not so ratify. Issue. At this point a change of venue was granted, on the application of the defendant, to Henry county. The cause was there tried by a jury and the plaintiff obtained a verdict and judgment for 1,500 dollars. A new trial was denied.
¶3On the trial the plaintiff was permitted to prove that letters had passed between herself and the defendant; and it was objected that this should not be done unless the letters themselves were produced in evidence.
¶4We think the plaintiff had a right to prove by parol the fact that letters had passed between the parties. After having proved the existence of the letters, it was at her option to introduce them or not in evidence, or to prove their contents or not if they were lost. If the contents of the letters were not introduced in evidence, the fact of their existence would pass for what it was worth; but its force' as tending to prove a marriage contract would be diminished, if not destroyed, by the contents of the letters being withheld.
¶5The Court gave this instruction to the jury, the defendant objecting:
¶6“ It was not necessary that the plaintiff should prove an express promise on her part to marry the defendant; but it may be inferred from the fact of her making no objection at the time, carrying herself as one consenting and approving, receiving his visits as a suitor, writing letters to him, and such like circumstances, indicating her assent. Her readiness and willingness to perform may be proved by her conduct and expressions and preparations for the marriage.”
¶7The fault found with this instruction is, that it assumes the facts recapitulated in it to be proved, and we think the jury might so have understood it. The jury are the sole judges of what facts are proved to them in a cause; and, in this case, the Court should have charged hypo*336thetically, saying to them that if they found that such and such facts were proved, they might find a promise, &c.
¶8The Court refused the following instruction:
¶9“ The jury have nothing to do with the fact that this case has been brought here on change of venue from the county of Rush. There is nothing in that fact that can legitimately prejudice the defendant or his cause.”
¶10This instruction should have been given. The attorneys for the plaintiff below should not have been permitted to use the fact of such change in argument.
¶11The defendant asked an instruction as follows:
¶12“In this case, if the jury believe from the evidence that the defendant, Conaway, was under age at the time the plaintiff assumes the contract was made, to find the defendant guilty, they must find that the contract was made by him while he was under age, or they have no inquiries to make as to what he may have said or done after he came of age that may look like a confirmation or ratification of the contract, for there is none in that case to ratify.”
¶13There was no error in refusing this instruction.
¶14Looking at it in reference to the trial upon the general issue, it was wrong; for a promise made after the defendant was of age, without any reference to a previous one while a minor, would support the plaintiff’s case under that issue.
¶15Looking at it in reference to the trial upon the issue on the replication to the plea of infancy, it was wrong; for the defendant, by that plea, admitted the original promise while a minor, and nothing remained to be proved but the ratification.
¶16The following instruction was refused on the ground that there was no evidence to which it could be applicable :
¶17“ Should the jury find, from the facts in evidence, that the case is made out, and that there was also seduction, it will be the duty of the jury to take into consideration, in mitigation of damages, any evidence that may appear of the easy virtue, want of chastity, or improper conduct, on *337the part of the plaintiff, at the time, or after the contract was made.” ,
¶18The only evidence that would render the instruction relevant, was, that “the plaintiff’s child was begotten at the defendant’s second visit to her as a suitor, (the first having been some five months previous,) in her mother’s room where the whole family were sleeping, and within arm’s length of where the plaintiff’s sister was, at the time, sitting with her suitor, though it is not asserted that the two latter knew of the sexual intercourse by which said child was begotten.”
¶19Where there is any evidence tending to establish a fact, its weight is for the jury, and it renders instructions upon the point relevant. We think the facts above stated amounted to some evidence for the consideration of the jury and that the instruction should have been given
¶20The judgment is reversed with costs. Cause remanded, &c.
