Messrs. Howell and Zirman have furnished me with evidonce, whih is períectly satisíactorV to me, tfcat ihey are really bound to Matamoras with a cargo inteoded for the Mexicana. I therefore very cheerfully give them this certiücate at theïr requeat. It is not the dispositioo of the Government of the United States to interfere in any way with an honest neutral trade, and it is deeply to be rogretted that the frauds which have been so estüiinively practiced in this country have contribated so muuh to throw it under suspiclon.
