Mr. Thurston to Mr. Gresham.

Sir: With farther reference to the alleged violation of the United States neutrality laws by Captain Martin of the schooner Wahlberg, I have the honor to inform you that I have received from Mr. Wilder, Hawaiian consul at San Francisco, a further statement concerning the witnesses. He states that he has found a deck hand of the tug alleged to have delivered the arms on board of the Wahlberg, who makes a clear and direct statement, making a valuable witness. He further states that the cook and mate of the Wahlberg were discharged from the Wahlberg upon her recent arrival at San Diego, and are now in San Francisco; also, that all of these men are liable to ship on outgoing vessels at an early date, so that if their evidence is to be obtained it will have to be soon, or it will become unavailable.

With renewed assurances, etc.

L. A. Thurston.
