necessary; and, although great difficulty will be experienced in obtaining forage and replacing horses that may be disabled, its services are so indispensably necessary, that I greatly regret my inability to supply more than one company on the Indian frontier until after the company now on duty with the commissioner of the boundary survey is relieved. I have heretofore called the attention of the War Department and the division commander to the insufficiency of the force assigned to this department by general order No. 49 of 1848. As it may not be possible, with the present military establishment, to order any additional force to this country without the action of Congress, I respectfully invite the attention of the commanding general to the views heretofore expressed on this subject. A topographical sketch of a portion of this department is herewith inclosed, upon which I have indicated the positions or neighborhoods in which I deem it important that troops should be established. The amount and character of the force required in my report to division headquarters, of June 11, is also inclosed. The embarrassments under which the service has labored will be so readily appreciated at home, that it is unnecessary to refer to them here except to say that, great as these embarrassments have been, they have been greatly increased by the want of line and staff officers. [Illustration: GOING TO A FANDANGO.] In consequence of the extraordinary prices of labor, and the consequent enormous expenditures in this country, young officers of the line should not be, in justice to the service and themselves, as they have unnecessarily been, encumbered, in addition to their company duties, with money and property responsibilities to a very great amount. Experienced officers of the quartermaster's department are required at San Francisco, San Diego, and with the commands on the upper Sacramento and San Joaquin Rivers. I have now but one officer, Captain Kane, of that department, under my control; and he is necessarily detained at department headquarters in the preparation of my estimates for the services of the ensuing year. Quarters must soon be erected at several of the posts in this department; and I cannot spare line officers for this duty, without destroying their efficiency with their companies, even were it proper to do so. There are no topographical engineers on duty in this department, and, in consequence of the want, I have been able to perform very little of the duty devolved upon me by the 111th paragraph general orders No. 49, of 1848. A reconnoissance of a portion of the valleys of the Sacramento and San Joaquin Rivers, undertaken for the purpose of determining the position to be occupied, as recommended in my report to division headquarters of April 16, to the War Department of the 25th of the same month, has strengthened my opinion of the importance of giving the country a most thorough examination before any military
