In your issue of Wednesday evening, in the postscript of telegraphic news from Mexico, an important error occurred in relation to the transmission of San Francisco news by our route. Your correspondent says: “The news came over the New Mexico or Ramsey route, and occupied about twenty-four days in its transmission.” The facts are as follows: The news left San Francisco on the 1st of October by the Nicaragua steamer Pacific; it arrived at Acapulco on the 8th, crossed Mexico, and arrived at Vera Cruz on the 12th, where the news remained from the 12th until the 22d, the regular sailing day of the Texas, (the steamer that carried the news, instead of the Mexico, as stated in your article.) If our steamer had left Vera Cruz on the arrival of the news from Acapulco, our merchants would have had the market prices in fifteen days from San Francisco via New Orleans. If it should be asked why the Texas did not sail until the 22d, the only reply we have to offer is, that she was running on schedule time appointed by the Post Office Department, and until that schedule is altered the delay is likely to recur. With a proper connexion, our line can deliver mails from San Francisco, into New Orleans weekly, in less than sixteen days. Respectfully, your obedient servant, ROBERT G. RANKIN, _President_. Be pleased to observe, by extract from Commercial Advertiser, the transmission of California news from California, by our route, in fourteen days! H. & M. * * * * * PACIFIC MAIL STEAMSHIP COMPANY, _New York, October 28, 1853_. GENTLEMEN: Having examined carefully the schedule proposed by you for running on the route between New Orleans and Vera Cruz, so as to connect at Acapulco with our steamers between Panama and San Francisco, I beg leave to inform you that it meets our approval. When our company commenced to run weekly boats, the schedule of the Texas was arranged to conform to the movements of those extra boats. It happened, however, that the United States Mail Steamship Company, although willing to perform extra service, and to let that service speak for itself to Congress, was not willing to bind itself as the government required, so as to shut out all prospect of extra remuneration by a liberal legislature for extra duty; and, consequently, the steamers, on intermediate weeks, on this side, were withdrawn. The connexion being thus cut off, our company was obliged to discontinue its weekly trips, after the schedule of the Vera Cruz and Acapulco route had been arranged to conform to those trips.
