[DANIEL RUGGLES.]

NEW ORLEANS, July 11, 1862.

His Excellency THOMAS O. MOORE,

Governor of Louisiana:

GOVERNOR: I have been informed than in several quarters of Louisiana and the authorities organized by the orders of Your Excellency wish to impose on French citizens not only active military service, but also to oblige them to enroll themselves in the corps which is organizing under the name of "guerrillas," or irregular corps. I cannot believe, Mr. Governor, that such acts can have your approbation, for I know that your Government os opposed to all imposition of obligatory active service upon foreign citizens. Neutrality in the midst of actual conflict is imposed not only by the law of nations, but also by the express orders to the Government of the Emperor, whom I have the honor to represent. As to service in irregular corps, it would be even more contrary to the duties which are imposed upon them and expose them to dangers, natural consequences of organizations, which all civilized nations equally disapprove.

I believe, Mr. Governor, that your spirit of justice, or which I have had more that one proof, will cause you to receive these observations favorably, but in the contrary case I shall be forced to protest in the name of my Government and of my compatriots any violence to which they may be subjected in reserving their right to give support to those who are responsible for the authorized of such acts.

Accept, Mr. Governor, the assurance of my respect and of my very high consideration.

MEJAN,

French Consul.
