SIR: You are hereby authorized to make up and send a mail by the Vera Cruz and Acapulco line, containing letters or papers expressly directed to go by that line, when said communication is open, and the contractors are prepared to carry a mail on the terms of their contract of February 15, 1853. You would do well, perhaps, to advertise to the above effect, adding that all letters, &c., not marked as above indicated, will be forwarded by the Panama route. Respectfully, your obedient servant, S. D. HUBBARD, _Postmaster General_. POSTMASTER, _San Francisco, California_. [Same to postmasters of New Orleans, San Diego, and Monterey.] * * * * * OFFICE OF THE MEXICAN OCEAN MAIL AND INLAND CO., _New York, June 15, 1853_. MY DEAR SIR: The position that our company sustains to the government, (as the real parties by contract,) to execute the mail contracts with Messrs. Ramsey & Carmick, renders it proper that the Post Office Department should be advised of the state of forwardness on the part of the contractors to fulfil the contracts. Our vice president, Colonel Albert C. Ramsey, is now in Mexico assigning the stations. In all this month and next month, the coaches, wagons, and literas will be in Mexico—portions of them being on their way now. By August 10 the mules and horses (1,000) will be down from Coahuila, and we then expect to make the regular transit across. Although the contracts only require a bi-monthly mail, we are making all our arrangements for a _daily line_ of transit across Mexico, feeling justified by the assurances we have from Mexico. We shall also establish a weekly line of steamers from New Orleans to Vera Cruz, (one steamer is now running there, and another now building;) and with the use of the new _envelopes_,(when they appear,) we shall actually afford a weekly line from New Orleans to San Francisco; and if the steamers on the Pacific could be arranged, we could make a daily line to San Francisco in sixteen days. Our land route will be daily, in any case, on account of our Mexican facilities. We have purchased and ordered the whole of the rolling stock for the transit, and parties are now in Mexico clearing obstructions, and we shall not, I think, require the full time allowed by the contract for the transit, although trial only will verify our expectations.
