A having possession of certain property of B, under a power of attorney to sell the same and execute the proper instruments of transfer, afterward gave the charge of the same, with deeds and papers in his possession, to C. A thereupon wrote to C: "I wish you to manage (my property) as you would if it were your own, and if a good opportunity offers to sell everything I have, I would be glad to sell. It may be parties will come into San Antonio who will be glad to purchase my gas stock and real estate." Held, that C was thereby authorized to contract for the sale of the real estate, but not to convey it. Lyon v. Pollock, 99 U. S. 668.
