No. 131.

Mr. Cheng Tsao Ju to Mr. Porter.

Sir: I have the honor to acknowledge the receipt of your note dated the 14th instant, and its inclosure, informing me that the district attorney of Wyoming Territory had been instructed to do all in his power to assist the proposed investigation by the Chinese commission into the recent riot at Rock Springs, and “to bring the evil-doers to justice.”

I beg to state that I have advised the members of the commission by telegraph of the facts kindly furnished.

Tendering to your Department and that of the Attorney-General my thanks for these gratifying efforts in aid of the Chinese commission, I avail myself, &c.
