Herewith inclosed is a communication for Governor Pesqueira, which I will thank you to forward to His Excellency. *

Honorable E. M. STANTON:

SIR: In the event of the Government deciding to build an iron-clad steamer, with ram or steel bow, permit me to say that I have every facility for building the same, together with engines and boilers. My foundry, machine-shop, blacksmith and boiler shops, and tools are equal to any in the Atlantic States, consisting of blooming furnace, Nesmith steam hammer for fording, a large lathe, the largest in California, and the same as the one in the Charlestown Navy-Yard; can forge and turn the largest shafts, punching and riveting machines of the largest sizes; also shoars. And I am now getting up a rolling-mill. I have on hand 300 tons of blooms made from wrought scrap, and have every variety of iron, and would, in the event of obtaining a contract, give any bond the Government would require for the entire completion of the ship and fulfillment of the contract to the satisfaction of the Government. I would respectfully refer to Senators Latham and McDougall, or any of the California delegation; to General Seawell, U. S. engineer, who superintended the building of the Saginaw at my works, or to any gentleman in Washington from California, for my ability to perform the work. Please telegraph me on receipt of this of it will be necessary for me to visit Washington.
