The order of the government conscribing all foreign residents who have acquired homes in this country, and the expulsion of the British consuls, will immediately be followed by another exodus of that class of residents. Already passports are daily applied for, and invariably granted by Mr. Assistant Secretary Campbell. The enemy, of course, will reap great benefit from the information conveyed by these people, and the innumerable brood of blockade-runners.

Gen. Lee has sent down between 600 and 700 prisoners captured in recent cavalry engagements. He took their horses and equipments also. And there is an account of an engagement in the West, near Memphis, in which the Confederate troops inflicted injury on the enemy, besides destroying the railroad in several places.

October 16th.—No battle had occurred in Northern Virginia up to 10 o’clock yesterday morning, although there is a constant stream of prisoners being sent to this city daily, taken by our cavalry. At last accounts Meade’s army was retreating toward Washington City, hotly pursued by Lee. They were near Manassas, the first battle-field of the war.

There is nothing new from the West, except some skirmishing of cavalry in Central and Western Tennessee, wherein our men have had the advantage, though sometimes falling back before superior numbers.

At Charleston a brisk cannonading is kept up between the batteries; and it is said more hostile transports are arriving, which may indicate active operations on land. Our 700-pounder Blakely No. 2 is there.

Judge Campbell is giving passports rapidly, sometimes binding the Jews not to engage in private operations, but to confine themselves, while in the United States, to the purchase of supplies for the Confederate States service! Some, however, are willing to go on these terms to avoid conscription, but will realize profit by selling information to the enemy.

Judge Hastings, of California, proposes to return thither and publish a pamphlet describing newly discovered gold mines, and organizing companies to work them, which shall be secessionists; and when organized, he will fall upon and destroy the United States troops, march into Arizona, and from thence pour reinforcements into Texas. The Secretary, in the absence of the President, sends a copy of this scheme to Lieut.-Gen. E. K. Smith, trans-Mississippi Department, and gives some encouragement to the judge; abstaining, however, for the present, from devoting any money to the project.

October 17th.—We hear to-day that a battle has taken place near Manassas, and that Lee has taken some 9000 prisoners and many wagons. At 3 p.m. there was no official intelligence of this event, and it was not generally credited.

Gen. Wise writes from Charleston, that it is understood by the French and Spanish Consuls there that the city will not be bombarded.

In Eastern North Carolina the people have taken the oath of allegiance to the United States, to be binding only so long as they are within the military jurisdiction of the enemy; and they ask to be exempt from the Confederate States tithe tax, for if they pay it, the enemy will despoil them of all that remains.
