Evidence that the agents of the owner of lands, with the approval of the owner, sold a part of them which had been intrusted to plaintiffs for sale, to persons who were found by plaintiffs, and induced by them to come on the lands with the purpose of purchasing, is admissible in an action against the owner for a breach of his contract in refusing to execute deeds to buyers found by plaintiffs. Burnett v. Edling, 19 Tex. Civ. App. 711, 48 S. W. 775.
