The ninth section of the act of July, 1862, authorizes "any line officer of the Navy or Marine Corps to be advanced one grade if upon recommendation of the President by name he receives the thanks of Congress for highly distinguished conduct in conflict with the enemy or for extraordinary heroism in the line of his profession," and Captain Stephen C. Rowan and Commander David D. Porter having each on my recommendation received the thanks of Congress for distinguished service, by resolution or the 7th February, 1863, I do therefore nominate Captain Stephen C. Rowan to be a commodore in the Navy on the active list from the 7th February, 1863. Commander David D. Porter to be a captain in the Navy on the active list from the 7th February, 1863. If this nomination should be confirmed, there will be vacancies in the several grades to which these officers are nominated for promotion. ABRAHAM LINCOLN. WAR DEPARTMENT, _Washington City, February 25, 1863_. THE PRESIDENT OF THE UNITED STATES SENATE. SIR: In answer to the Senate resolution of the 21st instant, I have the honor to inclose herewith a letter of the 24th instant from the Secretary of War, by which it appears that there are 438 assistant quartermasters, 387 commissaries of subsistence, and 343 additional paymasters now in the volunteer service, including those before the Senate for confirmation. I am, sir, very respectfully, your obedient servant, ABRAHAM LINCOLN. WASHINGTON, D.C., _February 25, 1863_. _To the Senate of the United States_: I nominate Passed Midshipmen Samuel Pearce and Nathaniel T. West, now on the retired list, to be ensigns in the Navy on the retired list. These nominations are made in conformity with the fourth section of the act to amend an act entitled "An act to promote the efficiency of the Navy," approved 16th January, 1857, and are induced by the following considerations: The pay of a passed midshipman on the retired list as fixed by the "Act for the better organization of the military establishment," approved 3d August, 1861, amounted, including rations, to $788 per annum. By the "Act to establish and equalize the grade of line officers of the United States Navy," approved 16th July, 1862, the grade or rank of passed midshipman, which was the next below that of master, was discontinued and that of ensign was established, being now the next grade below that of master and the only grade in the line list between those of master and midshipman. The same act fixes the pay of officers on the retired list, omitting the grade of passed midshipman, and prohibits the allowance of rations to retired officers. The effect of this was to reduce the pay of a passed midshipman on the retired list from $788 to $350 per annum, or less than half of previous rate.
