I have the honor to be, very respectfully, your obedient servant,

J. D. STEVENSON,
Colonel 1st New York Regiment, commanding S. M. District.

Colonel R. B. Mason,
1st U. Dragoons, Governor of California.

P. S.—Since writing the above, I have received the inclosed note from Don Pio Pico, inclosing a communication to your excellency. In the note of Don Pio to me, you will perceive that he is no sooner arrived at San Fernando than he claims to have returned to California as its Mexican governor, to carry out the provisions of the armistice. I shall not answer his note until I have heard from you; but I shall keep an eye on him, and if I find he is preaching sedition, I will bring him in here at short notice.

J. D. STEVENSON,
Colonel, commanding.

W. T. SHERMAN,
First Lieutenant 3d Artillery, A.A.A. General.

Appendix K.

On the 13th of April, 1849, Colonel Mason at his own request, was relieved from the post of Governor of California, and Brigadier-General Riley took his place. The despatch of that officer, dated 30th of June, following his assuming the duties of his post, is important, as containing an account of the state of feeling in California, upon the subject of the laws at that time in force, and the difficulties with various assemblies elected in the northern part of the territories.

Executive Department of California,

Monterey, June 30, 1849.
