Mr. Seward to Lieutenant General Grant
General: I have the honor to acknowledge the receipt of your letter of this date, enclosing for my perusal the prospectus of the Mexican Express Company forming in New York city, and the three slips taken from New York papers, throwing some light upon the operations of that company, with the view of aiding the so-called imperial government of Mexico.
In reply, I have the honor to state that the proper measures have been adopted by this department to prevent a violation of the laws of the United States, and the existing treaty stipulations between the United States and the Mexican republic.
In this connexion, I transmit for your information a copy of my note to Señor Romero, of this date, upon the same subject, a copy of which has also been forwarded to C. A. Seward, esq., of New York.
You will be pleased to accept my thanks for the information communicated by you to this department.
I have the honor to be, general, your most obedient servant,
Lieutenant General U. S. Grant, Commanding Armies of the United States, Washington, D. C.
