Charles I. Will and Barry & Morrissey, for defendant in error.

Mr. Presiding Justice Puterbaugh

delivered the opinion of the court.

This is an action in assumpsit by plaintiffs in error against defendant in error, for the recovery of damages resulting from an alleged breach of warranty of the title to certain chattel property purchased by them from the defendant in error.

The first count of the declaration alleges the execution by the defendant to the plaintiff of a bill of sale conveying “One (1) saw mill complete with all belts *404and attachments being the same saw mill with belts and attachments that formerly belonged to one John Aspel”; that thereafter one John Aspel replevied from them a vise, post drill, blacksmith forge, block and tackle with rope and pulleys, two chains, a log wagon, etc.; that after the commencement of the replevin suit by Aspel the plaintiff served notice upon the defendant to defend said suit; that the same was finally decided against the plaintiffs, whereby they lost the property in question, and in addition thereto were compelled to pay attorney’s fees and costs.

The second count alleges in addition, that at the time of the execution of said bill of sale, the defendant then and there represented to the plaintiffs that the property therein described comprised and included the property replevied. The defendant by its special plea averred that the question as to what was included in the description employed in the bill of sale was litigated upon the trial of the replevin suit, and determined adversely to the contention of the plaintiffs and that judgment was rendered therein in favor of Aspel, which judgment was still in full force and effect. To such plea the plaintiffs replied that at the time of the execution of the bill of sale the defendant was asked what property was comprised in and included in the description quoted, and that the plaintiffs then and there answered that the property afterwards replevied was included therein, and that by reason of the premises the defendant should be estopped to assert the contrary. A demurrer was sustained to said replication, and the plaintiffs having elected to abide thereby, judgment was rendered against them in bar of action and for costs. They thereupon sued out this writ of error.

Waiving the question whether there was an estoppel by verdict in the replevin suit, we are of opinion that the demurrer to the replication was properly sustained, for the reason that parol evidence was inadmissible for the purpose of showing that other prop*405erty not answering the description in the bill of sale was included or intended to be included therein. All verbal agreements made before or at the time of the execution of a written contract, concerning the subject-matter thereof, are conclusively merged into the written contract and cannot be added to or changed by parol evidence. Hill v. Hatfield, 72 Ill. App. 534.

Plaintiffs in error deny in argument that they are seeking to vary or enlarge the terms of the bill of sale, and assert that they seek merely to put the same construction upon its general terms as the parties themselves did at the time of the execution of the instrument. The words employed in the present contract are neither ambiguous, doubtful nor uncertain. It is clear that the property replevied could not under any reasonable construction be held to be included therein. The rule that where the terms of a contract are uncertain, and the parties have by their conduct placed a reasonable construction thereon, such construction will be adopted by the courts, is therefore inapplicable. The judgment of the circuit court is affirmed.

Affirmed.
