Discontinuance of mails.
--It is stated that the Post-Office Department have discontinued the steamboat mails on the Mississippi river all the way from St. Louis to New Orleans; the steamboat mail from Mobile via Lake Pontchartrain; the steamship mail from New Orleans via Pensacola, Apalachicola, Cedar Keys and Tampa Bay to Key West; also, all the steamship mails from New Orleans to the seaports in Texas, as Sabine City, Galveston, Indianola and Brazos Santiago. This makes a reduction of some $400,000 per annum of mail pay. These were all discontinued in consequence of the act of the United States Congress, at its last session, directing the Postmaster General to discontinue mails when the service was interrupted in any of the States.
