An agency may be terminated by the death of the principal. Crowe v. Trickey, 204 U. S. 228, affirming 71 P. (Ariz.) 965; Crowe v. Harmon, 204 U. S. 241, affirming 71 P. (Ariz.) 1125; Kyle v. Gaff, 105 Mo. App. 672, 78 S. W. 1047; Shisler's Est., 2 Pa. Dist. Ct. 588.

In an action by a broker for his commissions in negotiating an exchange of properties, reference in a single letter by one of the parties to the trade to the other, indicating that the proposition had been submitted to him by plaintiff, and the testimony of the other party that it was through plaintiff that he came to know the former, and that he had the property in question to trade, are not sufficient to show plaintiff's employment by the party writing the letter, where it does not appear that any demand for commissions was made by the plaintiff until the party's death, though he lived for some months afterward. Ehrenroth v. Putnam (Tex. Civ. App. '00), 55 S. W. 190.
