During the spring of 1857, the preparations for the expedition were hurried forward, and in June the whole force was collected at Fort Leavenworth. All Western Missouri was in a ferment. The river foamed with steamboats freighted with military stores, and the levee at Leavenworth City was covered all summer long with the frames of wagons. Between the 18th and the 24th of July, all the detachments of the little army were on the march, except a battalion of two companies of infantry, which had been unable to join their regiment at the time it moved from Minnesota, and the Second Dragoons, which Governor Walker retained in Kansas to overawe the uneasy people of the town of Lawrence. General Harney also tarried in Kansas, intending to wait until after the October election there, at which disturbances were anticipated that it might be necessary to quell by force. At Washington, movements of equal importance were taking place. The Postmaster-General, in June, annulled the contract held by certain Mormons for the transportation of the monthly mall to Utah, ostensibly on account of non-performance of the service within the stipulated time, but really because he was satisfied that the mails were violated, either _en route_ or after arrival at Salt Lake City. The office of Governor of the Territory was offered by the President to various persons, and finally accepted, July 11th, by Alfred Cumming, a brother of the Cumming of Georgia who fought multitudinous duels with McDuffie of South Carolina, all of which both parties survived. Mr. Cumming had been a sutler during the Mexican War, and more recently a Superintendent of Indian Affairs on the Upper Missouri. He was reputed to be a gentleman of education, ambition, and executive ability. The office of Chief Justice was conferred on Judge D.R. Eckels, of Indiana, a person well fitted for the position by the circumstances of his early life, of the utmost determination, and whose judicial integrity was above suspicion.
