Several new military departments were created by the subdivision of the military department of Washington.--(Doc. 105.)
The Virginia Sentinel of to-day, says, “ Our people must rest quiet upon the fact that the military preparations for our defence are under the direction of shrewd, skilful, indefatigable, experienced and patriotic officers. Our commanding general, Robert E. Lee, has long been the pride of the service, and he is supported by subordinates of acknowledged capacity and large experience. The plans of our Government are, of course, not suitable matter of public proclamation. Our military boards keep their own counsels, as it is obviously proper they should do. The people should patriotically abstain from even the attempt to unriddle them, for the wisest plans are often baffled by disclosure, however made. Let us trust with a generous confidence those to whose hands we have committed the conduct of affairs, and prepare ourselves to sustain them with all the power of a united and courageous people.”
 Five men were arrested at the Navy-yard, at Washington, where they were employed, having been discovered filling bomb-shells with sand and sawdust, instead of the proper detonating material. They were confined in the Capitol, under guard of the Seventh Regiment.--N. Y. Times, May 1.
The Fifth and Eighth Massachusetts Regiments arrived at Washington yesterday morning, followed immediately by the Rhode Island forces. This morning, about six o'clock, the Seventy-first New York marched in from Annapolis Junction. It made a magnificent appearance as it swept down the Avenue, with its fill bands playing. The men looked less fatigued than those of either of the other regiments, and were warmly commended by the citizens as they passed, and by the officers and men of the other regiments who were out to witness their entrance into the city. Next to the Massachusetts men they showed the greatest capacity to endure fatigue.--(Doc. 106.)--The World, May 1.

A number of residents of Virginia passed through Chambersburg, Pa., en route for the North. Many of them have left every thing behind, and are obliged to depend upon the charities of the people to continue their journey. All who come from as far south as Richmond, could get out of the State only by a special permit from Governor Letcher. Their statements show that a reign of terror exists in the interior of Virginia. The mob everywhere appropriate to their own use whatever they may fancy; farmers are stopped on the road, their horses taken from them under the plea that they are for the defence of the South; granaries are searched, and every thing convertible for food for either man or beast carried off. This has been practiced to such an extent that along the northern border of Virginia a reaction is taking place, and instructions are being sent from Western Maryland, to the Delegates at Annapolis, that if they vote for secession the people will hang them on their return home. The news of the unanimous sentiment of the North, the prompt and decisive action on the part of the State Governments in enlisting men, has strengthened the Union men of Western Maryland and the border counties of Virginia.---N. Y. Tribune, April 28.
A sudden and wonderful change takes place in the sentiment of Maryland. The American flag was raised at Hagerstown, and extensive preparations are being made for further Union demonstrations. Alleghany county has instructed its representatives that if they vote for secession, they will be hung on their return home. The Stars and Stripes are waving over Frederick City. The Home Guard refuse to parade unless its folds are displayed, and the tune of Yankee Doodle played. At the Clear Spring House the Stars and Stripes are waving, and the miners have sworn to resist secession to the death.--N. Y. Courier and Enquirer, April 28.

A number of French residents of New York held a meeting this afternoon for the purpose of taking measures with reference to the present state of the country. Messrs. Fremont, Quesne, and Faidu were appointed a Committee to conduct the proceedings. M. Victor Faidu stated the object of the meeting, and proposed that it be made preliminary to a general meeting of French citizens for their proper organization to participate in the present conflict — it was their duty to support the Government of the United States in this strife between human liberty and freedom against slavery and feudal oppression.

Fremont offered resolutions tendering the support of French citizens to the United States, but he hoped that the government, if the contest was carried to the extreme, would guarantee the total abolition of slavery.--N.
