To entitle a broker to commissions, where the contract concluded differs from that which the broker was authorized to negotiate, the negotiations commenced by the broker must have continued uninterruptedly, and he must have been actively instrumental throughout in causing the parties to consummate the transaction, and the sale made was satisfactory to the owners. Woods v. Stephens, 46 Mo. 555; Gold v. Sorrell, 26 N. Y. S. 124.

A broker employed to procure a purchaser of realty for a fixed per cent. of the price, not specified, opened negotiations with a third person and introduced him to the owner. The third person never made any offer to the broker, and the owner refused to give the third person any price or terms, because others were then negotiating for the property. The broker made no further efforts to bring the parties together. Many months later the owner contracted a sale to the third person. Held, that the broker was not entitled to commissions. Wheeler v. Beers (Colo. Sup. '09), 101 P. 758.
