The claim of the appellee is for damages resulting from the defendant’s rescission of a contract to purchase yarn. The contention of the appellant is-that time was of the essence of its contract with the plaintiff, and, as the latter had failed to make the deliveries required by the contract, it had the right to rescind. A jury trial was waived and the case was tried before the learned president judge of the court below under the provisions of the act of April 22, 1874. He found that it was the understanding of the parties, confirmed by the course of dealing between them, that the times and quantities of the deliveries were not of the essence of the contract, but could be varied from time to time as circumstances might dictate, and that the times and quantities of the deliveries specified in the contract were not observed strictly by either the plaintiff or defendant nor insisted upon by either. The evidence in the case fully justified this finding, and the defendant could not, therefore, suddenly rescind its contract with the plaintiff without a fair warning of its intention to insist upon a literal compliance with it in futuro: Forsyth v. North *299American Oil Co., 53 Pa. 168. In assessing the damages to which the plaintiff was entitled the rule was followed as laid down in Unexcelled Fire Works Co. v. Polites, 130 Pa. 536; Jones et al. v. Jennings Bros. & Co., 168 Pa. 493, and Sharpsville Furnace Co. v. Snyder, 223 Pa. 372.

The check accepted by the plaintiff, with the words written on the face of it “account in full,” merely paid the amount due for the goods shipped up to December 16, 1907, and was, of course, in full payment of that account, but, as the court correctly found, “It was no release on the part of the plaintiff of any damages it may have sustained by reason of the rescission of the contract.”

The assignments of error are overruled and the judgment is affirmed.
