On the previous evening,--March 12th,--the monotony of the camp had been unexpectedly disturbed by the arrival, from the direction of Salt Lake City, of a horseman completely exhausted by fatigue and cold, who proved to be no other than Mr. Kane, whose mission to the Mormons by way of California was at that time totally unknown to the army. The next morning he introduced himself to the Governor, was received as his guest, and remained in conference with him throughout the day. What was the character of their communication is unknown, except by inference from its results. When presented to Judge Eckels, on the following day, Mr. Kane exhibited to him the letters he bore from the President, and other letters, also, from Brigham Young, accrediting him as a negotiator in the existing difficulties. To General Johnston he showed nothing; nor did the Governor, to the knowledge of the camp, acquaint either that officer or any other person with the purport of his business. It was evident to everybody, however, that the Mormon leaders, conscious of their inability to resist the force by which they would be assailed so soon as the snow should melt upon the mountains, were engaged in an effort, of which Mr. Kane was the agent, to secure through the Governor, if possible, indemnity for their past offences, in consideration of acknowledgment of his authority. The domestic condition of the people of the Valley confirmed the belief that this was the purpose of Mr. Kane's mission. Dependent as they had always been, since their settlement in Utah, upon Eastern merchants for an annual supply of groceries, dry goods, wearing-apparel of all descriptions, and every article of luxury, their stock of some of even the necessaries of life--such as coffee, tea, sugar, tobacco, calicoes, boots and shoes, stationery--was at this time nearly exhausted. Many of the poorer families were actually half naked, and, to supply them with covering, an ecclesiastical mandate had been issued, directing all persons who had spare clothing of any description to deposit it at the tithing-office in Salt Lake City, to be there exchanged for grain and cattle with those who were in need.
