Major-General Smith has issued elaborate orders re-lative to the movement of the trains and troops of the Utah forces. The trains are to be divided into divi-sions of two hundred and twenty-six wagons each, and the troops will be organized into columns, each column constituting the escort of a division. A general supply train, and the first column under command of Lieut.- Col. Andrews are already organized, and ordered to march. The second column, under Lieut.-Col. Mun-roe, composing the escort of the first division of sup-plies, march from Leavenworth on the 15th inst. The third column, under Col. May, marches on the 20th. The fourth column, under Col. Morrison, marches on the 25th. The fifth column, under Col. Sumner, marches on the 30th. The sixth column, under Major Emory, marches on the 4th June. These columns for the present constitute the first brigade of Utah forces, under command of Gen. Harney. Each column is to be supplied with four months' provisions, which are to be replenished when passing Forts Kearney and Laramie.
General Smith is now in this city, and it is stated that his health is such as to require him to remain here a short period.
Four companies of the Sixth infantry left Leaven-worth on the 6th inst. One company from Fort Riley will join them at Fort Kearney.
John Hartnett, Secretary for Utah, left yesterday for Leavenworth.
