The appellee declared for two sums of $600 each, one of which was payable if Rockwell should sell certain premises on the Bobtail lode, which are described in the declaration. There is no evidence that these premises were sold. One witness swears that Rockwell had property on the Bobtail lode to sell for several parties, and another testifies to an admission by appellant that some property on the Bobtail lode had been sold, but it does not appear that the premises described in the declaration were sold. The contract should have been proved as laid. The judgment of the district court is reversed, with costs, and the cause remanded for a new trial.

Reversed.
