The negro-stealing at Key West.
--From an official repot, it appears that Capt. Meigs, of the U. S. Army, has been acquitted by President Lincoln of the complaints which followed him from Key West, on his return from reinforcing the fortifications in the Gulf, in relation to carrying slaves hired to work at Key West to Pensacola and Fort Pickens, and there employing them. It is contended that the contract has not been in reality violated — though it was — and that ‘"it is not to be presumed that the slaves will be compelled to become combatants at all, except in a case where military necessity would justify making any persons found in the fort become combatants."’
