they have made, and the moneys they have expended, under inducements the Post Office Department held out to them, for such efforts and expenditures, _by granting a through-service and arranging schedule for connexion_; and respectfully petition that you will so alter the schedule between New Orleans and Vera Cruz for the two trips per month, now being performed, as will give them an opportunity of proving to Congress that this is by far the most expeditious route yet opened to the rich commerce of California; which proofs, they feel, must necessarily insure the appropriations that shall furnish the means to enable them eventually to carry the mails between the two great points in the short space of thirteen days! Believing that your sense of justice, and desire for advancing the mails in accordance with the progressive ideas of this essentially progressive age, will induce an assent to their prayer, they have the honor herewith to submit such _temporary_ schedule, for the said two trips per month, as shall furnish the desired proofs; and, with sentiments of regard and esteem, subscribe, respectfully, yours, The MEXICAN OCEAN MAIL AND INLAND CO.; and CHARLES MORGAN, per HARRIS & MORGAN, _of New Orleans_. Hon. JAMES CAMPBELL, _Postmaster General United States_. _Schedule._ Leave New Orleans 7th and 22d; Arrive at Vera Cruz 10th and 25th. Leave Vera Cruz 14th and 29th; Arrive at New Orleans 17th and 2d. * * * * * OFFICE OF THE MEXICAN OCEAN MAIL AND INLAND CO., _New York, October 29, 1853_. DEAR SIR: Herewith please find a letter addressed to our firm from the president of the Pacific Mail Steamship Company, explaining why the schedule of running on the Pacific has been changed, (thus rendering _useless_ the _present schedule_ between New Orleans and Vera Cruz;) and, further, approving the schedule which we had the honor of submitting for your consideration in our memorial, dated in Washington, D. C. Trusting the views of our case, to which your attention has been called, will induce a favorable decision, we have the honor to subscribe, with sentiments of regard and respect, Your obedient servants, HARRIS & MORGAN. Hon. JAMES CAMPBELL, _Postmaster General United States_. * * * * * [For the Commercial Advertiser.] OFFICE OF THE MEXICAN OCEAN MAIL AND INLAND CO., _New York, October 27, 1853_.
