[1] The sole issue ot fact in this case was whether plaintiff bought the mule from defendant for the price of $40, as claimed by plaintiff, or for the price of' $140, as claimed by defendant. On this issue it seems to us that the evidence preponderated somewhat in favor of plaintiff; at least, it was in such conflict that we cannot disturb the finding of the trial court, who-saw and heard the witnesses, and can better. judge of their credibility than can we.

As tending to show the greater probability of defendant’s claim as to the price agreed on, his attorney asked him what was the-reasonable market value of the mule at the time he sold it to plaintiff.

[2] In the absence of any explanation to-the court that the answer would tend to show a value very greatly in excess of $40, if not of approximately $140, it is clear that the question was properly excluded as irrelevant. Non constat, but the answer may have been, that the value was but $40- or $50, and hence-prejudice from its exclusion does- not appear..

We need not determine whether, if it had appeared that the answer would have been, that the value was $140, or thereabouts, that fact would have been relevant to the credibility of the respective claims of the parties, as tending to show the probability of the one, or the improbability of the other. See, however, for analogous instances, Brewer v. Watson, 65 Ala. 88, 97; Langworthy v. Goodall, 76 Ala. 325; Steen v. Swadley, 126 Ala. 616, 28 South. 620.

The judgment will be affirmed.

Affirmed.
