you to load on at New San Pedro any more subsistence stores than you will require for the use of your command on its march, say to Carriso Creek. I find a good supply at this camp, and have sent to San Diego for twenty wagon loads, so you can load with barley, ay 2,500 pounds per team, including the other stores which you are to bring, and including your baggage, &c. ; thus your teams will be fresh. If you find any barley or corn at Clancy's, or at Temescal, Temecula, Camp Wright, San Felipe, or Carriso Creek, you can keep your supply up to the origianl mark at Camp Drum. There are some paulins at Greenwade's which you must bring. Inclosed is an order for Surgeon Christian and Lieutenant Frink to come forward. They are to come with you in case you have left. Be sure they come with you, and be sure that they have but the regulation allowance of baggage determined by the scales. The howitzer ammunition, percussion caps, cartridges for revolvers, army size, &c., which may have come down, you are to bring. Have the troops walk at least half the time, and have at least two hours' halt to grazxe midway each day's march. The soldiers must be drilled at the saber exercise on horseback while marching at least an hour each day. The horses must be kept fresh and in good condition, even though the men walk most of the way. Please get from Mr. Banning two of Captain Moore's umbrellas and bring them on. No news yet from Tucson.

I am, major, respectfully, &c.,
