¶1This was an action of assumpsit brought by appellee against appellant on an alleged guaranty of payment of $653.94 due and owing to appellee by E. W. Post & Co., of Denver, Colorado. The declaration contains but one count, which, after reciting that Post & Co. were indebted to the plaintiff in the sum of $653.94 on an open account for goods sold and delivered, and that the plaintiff was about to proceed to enforce the collection thereof, alleges that the defendant, in consideration that the plaintiff would forbear pressing Post & Go. upon one half of said sum for sixty days, and the other half for four months, promised and guaranteed to the plaintiff in writing that said account, to wit, the said sum of $653-.94, should be paid to the plaintiff within four months from the 18th day of March, 1881. •
¶2The defendant pleaded non-assumpsit, and a special plea alleging fraud in obtaining the execution of the guaranty. Issues were joined on these pleas, and upon the trial, the plaintiff, to support his declaration, offered in evidence a guaranty executed by the defendant in the words and figures following :

¶12To the introduction of this instrument in evidence, the defendant objected on the ground of a variance, it not being the instrument described in the plaintiff’s declaration. The court overruled the objection, and admitted the instrument in evidence, and the defendant excepted.
¶13The ruling of the court was manifestly erroneous. The undertaking, as alleged in the declaration, was to pay $653.94 within four months, while that shown by the instrument offered in evidence, was to pay one half the amount in sixty days, and the other half in four months. These are two very different contracts. According to one of them the defendant is. to have four months’ credit on the whole amount, while according to the other he is to have four months on one half only. The rule need hardly be stated that the allegations and proofs must agree, and allegations which are essential!}*descriptive of the contract must be proved strictly. Such allegations go to the identity of the contract. Of these are names, amounts, duration, and the like. They must be proved as set forth, or the variance will be fatal. Spangler v. Pugh, 21 Ill. 86.
¶14For the error of the court in admitting the instrument in evidence, the judgment must be reversed, and the cause remanded for further pleadings.
¶15Reversed and remanded.
