No. 380.
Mr. Frelinghuysen to Mr. Valera.

Sir: Referring to your note of the 18th instant, I have the honor to say that the Attorney-General has sent me a copy of a letter of the 21st instant from Mr. Root, United States attorney, intimating, in view of your above communication, that very probably you were in possession of some specific information as to the place where and the persons by whom such manufacture of explosives as your note contemplates is conducted. The attorney observes that when he receives any such information he shall employ all means in his control to prevent or suppress it. Doubting not that any information in this direction which may reach you will be communicated to me for the end proposed,

I improve, &c.,

FRED’K T. FRELINGHUYSEN.
