which the U. S. military forces have a right to pass through any portion of the Republic of Mexico. If such an arrangement has been made, I beg you will forward to me be express and official copu of it. I have been endeavoring to accumulate supplies at Fort Barrett. To this end every wagon has been at once employed as soon as it reached here from the desert. I could not afford to have but force enough there to make all safe until this was done, as theremainder could be subsisted herecheaper in point of time and labor of trains than there. What may have appeared as a delay is really the gaining of time. I have received the generals kind and considerate letter in relation to the effort which has been made by some persons in Los Angeles to cast a suspicion on my loyalty and my integrit. So the general pays no heed to this I think I can well afford to be abused. If such men as these who have abused me had complimented me, I should at once have cast about to see wherein I had done some rascally act.

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

LIEUTENANT: The Apaches made a foray in this vicinity this morning and killed three Pimas. Captain Pishon's Cavalry is looking after them, but I have little hopes of their coming up with them. The Pimas and Maricopas complain bitterly that the Apaches have fire-arms and that they can get none. If the colonel commanding can procure some arms for issue to them it would be of much benefit to us in our negotiations about supplies. The manta, calico, flannel, and drills arrived yesterday. About 30,000 pounds wheat ave been taken in since, and nearly all outstanding credits redeemed.
