In addition to harvesting his own crops, Dr. Whitman taught the Cayuse how to farm. He believed that agriculture and his missionary work were inseparable:
“. . . although we bring the gospel as the first object we cannot gain an assurance unless they are attracted & retained by the plough & hoe, & in this way even before the language is acquired you may have the people drawn arround you & ready to hear your every instruction. And why should not this be our method of proceeding; Is it not what Paul meant when he said, "I become all things unto all men," that he accommodated himself to the circumstances of the People? Why then should we not take the best, & may I not say, the only means to win them to Christ? Had I one doubt of the disposition of the Indians to cultivate I would not thus write; But having seen them for two season breaking ground with hoes & sticks & having given them the trial of the plough, I feel an entire confidence in their disposition & ability.”
The efforts at farming, at least, seemed to be going well. In 1842 Narcissa wrote: “The success of the Kayuses in farming is pleasing beyond description. There is scarcely an individual of them but what has his little farm some where & every year extending it farther & farther. A large number of the Walla Walla tribe are doing the same.”
