delivered the opinion of the court.

The general'rule is that the measure of damages in actions for the conversion of personalty is the value of the property at the time of the taking, with legal interest thereon from the date of the taking to the date of rendering verdict. It was. error for the court to refuse to give *101an instruction' to this effect, as requested by plaintiff’s counsel. The error, however, is not material upon this review, unless it be found, that other error was committed which may have improperly caused the trial to result in favor of defendant. Refining Co. v. Tabor, 13 Colo. 59; Oppenheimer v. Railway Co. 9 Colo. 321.

The charge of the court, as given, other than the matter relating to the measure of damages, appears to be unobjectionable. The principal matter complained of is the refusal of the court to charge the jury as requested by plaintiff’s counsel. It is the right of a party to pray instructions in writing to be given to the jury at the proper time; and when instructions thus prayed state the law applicable to the issues and the evidence with substantial accuracy, they should be given in substance.

The instructions prayed in behalf of plaintiff were numerous and. comprehensive. They were each and all refused. Ordinarily, an extended charge, such as was requested in this case, would be altogether unnecessary, and perhaps injurious to the ends of justice, in a trial by jury. But the question of fraudulent intent in actions of the kind under consideration is often a complicated one. The acts which a failing debtor, situated as Conant was, may or may not lawfully do, depend upon a variety of circumstances and conditions. The law relating to such transactions is familiar to the legal profession, and may be supposed to be -generally understood by business men engaged in commercial pursuits. Nevertheless, a jury may be composed of men whose minds are comparatively uninformed upon the subject. Hence, it is important, in such cases, that the jury shall be guided in their deliberations by the learning and experience of the presiding judge.

. We shall not undertake to review all of the instructions prayed in behalf of plaintiff; a few will suffice for the purposes of this opinion. Under the issues, evidence and circumstances developed at the trial, if Conant, at the time of making the sale, was insolvent or unable to pay all his *102debts, that fact did not deprive Mm of the power or render •it unlawful for him to make such sale. A debtdr in such condition may lawfully sell and dispose of his property, provided he does so for a fair and adequate and valuable ■consideration paid or to be paid by the purchaser, and from lawful motives, or without fraudulent intent as respects his creditors. His motives will be presumed to be lawful and •his intent not fraudulent until the contrary is shown. Insolvency, if it exists, is only a circumstance to be taken into consideration by the jury in determining the question of fraudulent intent, for which alone the sale may be set aside. Of itself insolvency constitutes no obstacle to the sale or to its lawfulness or validity, if fairly and honestly made. An ■instruction to this effect was requested by plaintiff. It was error to refuse it.

• So, too, it was error to refuse to charge the jury in substance that a debtor, situated as Conant was, might lawfully prefer some of his creditors to others, and pay some of them in full, leaving others partially or wholly unpaid so far as he should be without means of payment, and might lawfully sell and dispose of his property for a fair, adequate and valuable consideration for the purpose of making such payment or payments; that the law permits an insolvent debtor to make choice of the creditors he will pay, and the mode or means by which he will make such payment, and that something beyond such preference or payment must appear before the transaction is to be considered fraudulent. The preference of creditors by a failing debtor is not necessarily fraudulent. Campbell v. Iron Co. 9 Colo. 60; Bank v. Newton, 13 Colo. 256.

It is not our province to pass upon the weight of the evidence relating to the question of fraudulent intent, nor do we intimate that the verdict would have been different if the refused instructions had been given as prayed; neither must we be understood as saying that the trial court should have given all or any of the refused instructions m the precise form and manner as requested; but, as we have seen, *103since some of them correctly stated, the law applicable to the issues and evidence, such correct instructions, or, in their stead, others in substance like them, should have been given to the jury. Boyce v. Stage Co. 25 Cal. 470; Continental Imp. Co. v. Stead, 95 U. S. 166.

What we have already said will undoubtedly be sufficient to guide the court below on a retrial of the case without further expression of opinion as to the other instructions refused. We refrain from going further lest we might mislead rather than aid the trial court in so doing. Instructions should be appropriate to the evidence as introduced under the issues at the trial. They should be such as will properly guide the jury in their deliberations upon the particular matters brought before them for determination ; hence, instructions cannot always be anticipated with safety, even where there has been one trial, inasmuch as the evidence may be different on the second trial.

The judgment of the district court is reversed and the cause remanded.
