Though the taking of notes payable on or before maturity was a technical variation from authority to sell on time at a specified rate of interest, the vendor waived his right when, on seeking time for delivery of possession, he wrote to his broker that everything else would be all right. Watkins v. Thomas (Mo. App. '10), 124 S. W. 1063.

The vendor's right to demand that the broker put him in direct communication with the purchaser may be waived. Henry v. Harker, 122 P. 298, 61 Or. 276, aff. judg. on re., 118 P. 205, 61 Or. 276.

Broker entitled to commissions, although contract made on different terms, where variance is waived by owner. Brown v. Mason, 99 P. 867, 155 Cal. 155, 21 L. E. A. (N. S.) 328.
