By the document I respectfully inclose to you, I hope my mission to you is of a diplomatic character, and will be fully explained to you. Permit me to proceed or have the kindness to come to this place. Remaining at this place and expecting your permission to pass.

I most respectfully have the honor to subscribe, your obedient servant,

Citizen Lieutenant Colonel Frederick A. Romstedt passes to the Territory of Arizona (United States) with an important commission of the public service of this State.

Wherefore, it is particularly recommended that the authorities upon his route lend the said citizen lieutenant-colonel all the assistance that he amy ask of them and even armed force, the better to insure the success of the important commission with which he is intrusted.
