He also describes the orderly Sunday at the Mission. Up to the year 1838 the principal meat used as food by the Mission was horse flesh. The cattle were too few to be sacrificed in that way. In 1837 Mrs. Whitman writes in her diary: "We have had but little venison furnished by the Indians, but to supply our men and visitors we have bought of the Indians and eaten ten wild horses." In 1841 their stock of hogs and cattle had so increased that they were able to make a partial change of diet. Another witness to the value of Dr. Whitman's missionary work is Joseph Drayton, of Commodore Wilkes' exploring expedition of 1841. He says of the Mission: "All the premises looked comfortable, the garden especially fine, vegetables and melons in great variety. The wheat in the fields was seven feet high and nearly ripe, and the corn nine feet in the tassel." He marks the drawbacks of the Mission: "The roving of the Indians, rarely staying at home more than three months at a time." "They are off after buffalo," and "again off after the salmon," and "not more than fifty or sixty remain during the winter." These Cayuse Indians were not a numerous band, but they were born traders, were wealthy, and had a great influence over other tribes. Their wealth consisted mainly in horses; a single Indian Chief owned two thousand head. One of their good qualities Mrs. Whitman speaks of, is, "there are no thieves among them." She has to keep nothing locked out of fear from thieves; but they had one trying habit of which Mrs. Whitman had great trouble to break them--that was, they thought they had a right to go into every room in the house, and seemed to think that something was wrong when deprived of visiting the bedrooms of the family. In June, 1839, a great sorrow came to Dr. and Mrs. Whitman. They had but one child, a little girl of two years and three months old. In their isolated condition one can easily imagine what a large place a bright and attractive child would have in the heart of father and mother in such a home. In the pursuance of his duties the doctor was absent night after night, and some of his more distant patients occupied him frequently many days. It was at such times that Mrs. Whitman found great comfort and happiness in her little daughter. The child had learned the Indian language and spoke it fluently, to the delight of the Indians, and had learned all the songs sung in the Nez Perces dialect, having inherited the musical talent of her mother. It was in September, 1839, that she was accidentally drowned in the Walla Walla River. In her diary Mrs. Whitman writes to her mother:
