WASHINGTON, _December 15, 1851_.

_To the Senate of the United States_:

I have received a resolution of the Senate, adopted on the 12th instant,
in the following terms:

_Resolved_, That the President of the United States be requested to
communicate to the Senate, if not inconsistent with the public interest,
any information the Executive may have received respecting the firing

In answer to this request I submit to the Senate the accompanying
extracts from a communication addressed to the Department of State by
Mr. Joseph L. White, as counsel of the American, Atlantic and Pacific
Ship Canal Company, dated 2d instant.

by the Executive in relation to the subject alluded to, and is presumed

this communication instructions such as the occasion seemed to demand

to this dispatch from him, and in my judgment it would at the present

to the public interest will permit.

At the same time instructions were given to Commodore Parker, commanding
