SPEER, J.

Continental Lumber & Tie Company prosecutes this writ of error from an adverse judgment in an action instituted by it against P. H. Miller to recover for two car loads of lumber as upon a verified account under the statute.

[1] The contention that the trial court should have instructed a verdict for plaintiff in error cannot be sustained. The insistence seems to be that, since a demurrer was sustained to the cross-plea of defendant in error, and since plaintiff in error’s cause of action was evidenced by a verified account under the statute, there remained nothing, therefore, to be determined under the pleadings, and a verdict should have been directed. It is a sufficient answer to this, however, that defendant in error, under oath, denied the justice of the claim sued on. In such a case, the prima facie character of the proof is destroyed, and the burden rests upon the plaintiff, as in ordinary cases, to establish his cause of action. Olive & Stirnenberg v. Hester, 63 Tex. 190; Rust v. Sanger Bros., 105 S. W. 66; Pitman v. Bloch, 48 Tex. Civ. App. 320, 106 S. W. 724.

[2] There was error, however, in the following paragraph of the charge: “In this-case, you are instructed that if you believe from the evidence that upon the arrival of the two ears of lumber in question at Baird,. Tex., the defendant took possession of said-lumber and unloaded the same in his yard for the purpose of appropriating said lumber, or any part thereof, to his own use, then you will find for the plaintiff for the reasonable market value, if any, of said two cars-of lumber, with 6 per cent, interest from. December 8, 1908; and, unless you so believe, you will find for the defendant.” The particular portion which is prejudicial to plaintiff in error is contained in the last clause, directing a verdict for defendant in error, unless the jury should believe the lumber had been received and unloaded for the purpose of appropriating the same, or some part thereof. Under the evidence, the-jury would have been justified in finding that the lumber was actually received and unloaded with no intention of accepting the-same as in full compliance with the contract of purchase and sale; but afterward defendant in error formed in his mind the purpose to accept the lumber, and to hold plaintiff in error for the loss or damage growing out of the failure of the shipment to meet the requirements of his contract as-to grade, etc. In the event of such a finding, of course, on the most elementary principles, the defendant in error would be liable, not for the contract price, but for the reasonable-market value, of the lumber received, not to-exceed the contract price. It is too well settled to require a citation of authority that a purchaser in such a case may exercise the-remedy of rescission upon discovering that the goods tendered for delivery do not comply with the terms of his contract of purchase ; or he may waive this failure, retain the goods, and hold the seller for the-default. It cannot be the law, as the jury in effect were instructed that defendant in error would owe nothing for the lumber, unless, at the time the same was unloaded in-his yard, it was done so for the purpose of appropriating the same to his own use. In-the manner in which the issues were submitted, it became unnecessary to give plaintiff in error’s special charges concerning the- *736 issue of arbitration tendered by defendant in error. Such issue was effectively ignored in the presentation of the case. It may be doubted if defendant in error’s pleadings are as full as they should be, upon the issue of the failure of plaintiff in error to furnish lumber according to the contract of sale and purchase, to show specifically what loss he has sustained in the event of a finding that he has accepted the lumber. But we have not felt free, after having' reversed a recovery in his favor, to render the judgment against him for the want of such a plead.-ing. The cause will therefore be remanded for another trial.

Reversed and remanded.
