The contract averred in the second count of the plaintiff’s declaration, being proved 'to the satisfaction of the jury, nothing can be clearer than his right to recover the full amount of the debt which the defendant undertook, but failed to discharge. It is totally unlike the casé of a surety, who, though bound to pay, cannot maintain an action against his -principal, until he has actually paid; for it is only then his principal is in default. But here, one for a valuable consideration received, undertook, absolutely, to pay a debt for which another is responsible. No time being expressly ascertained, within which the agreement is to be performed, the law allows to the promisor a reasonable time. But, regardless of his obligation, he permits nearly five years to roll round; at the end of which time the original debtor is sued, before he institutes an action upon the agreement of the defendant. For the breach of such an undertaking, the measure of damages is the amount the defendant undertook to answer, and to which the plaintiff remains subject. It is not necessary he should have paid; it is enough that he is compellable to pay. The undertaking of the promisor is violated by leaving him open to be called on; and the case affords no other standard than the whole sum for which he remains liable. The answer of the court to the fourth and fifth points was therefore correct.
There is nothing in the third assignment of error. The testimony of the witnesses named in it did not necessarily contradict Mrs. Fross. Were this otherwise, being at most but a mistake of fact, it is not imputable here as error.
The instruction that it was the duty of the jury to endeavour to reconcile apparently conflicting testimony, was so tritely right, it is strange counsel should have thought of complaining of it.
Judgment affirmed.
