From Washington.
Washington, March 10.
--A Cabinet meeting was held last night on other subjects than appointments to office.
The condition of the Southern forts held by the Federal troops engaged the deep attention of Gen. Scott and others, yesterday.
From recent information it appears there is much dissatisfaction in the army even on the frontiers.
Secretary Seward will be able to attend to his duties to-morrow.
A number of subordinate officers in the army have resigned, and others are preparing to follow their example.
There appears to be but little doubt in the best informed political circles to-night, that it was decided in Cabinet meeting last night to evacuate Fort Sumter.
