of sore backs. This, however, is in part owing to the inferior quality of the pack saddles used (the McClellan pattern), and the unsuitable kind of saddle blankets, which are little better than cotton rags.

I have given above all the information asked for in your telegram. I am preparing a more detailed report of the operations of the quartermaster's department during the late cavalry operations of General Stoneman's command, and will send you a copy as soon as completed, which will be in a day or two. The scattered condition of this command since oui return has prevented my obtaining all the data necessary to a full report before.

I am, colonel, very respectfully, your obedient servant,

C. G. SAWTELLE,

Lieutenant-Colonel, Chief Quartermaster Cavalry Corps.
