lartrira.—We have advices from America to the 20th instant. The

Federal army commenced its march upon Richmond on the 17th instant, and was interrupted at Dulbram, where the Confederates drove back the advanced guard, but the position was ultimately car- ried. Fairfax has been occupied, and the Federal army is supposed to be in march on the Manassas Junction. This point is the key to

the railway which runs straight across the Manassas Gap, a broad pass nearly ten miles across, in the mountains which divide the great bulk of Virginia from its north-east corner. Through this gap the Federal troops wait march to reach Richmond, and the Confederates have accordingly concentrated their forces for its defence. Their army is supposed to be sixty thousand strong—a figure of which there is not the smallest proof—encamped behind an entrenched position de- fended by a strong park of artillery. The action of Congress has as yet beeen most decisive. The House of Representatives has pledged itself by a formal resolution, carried by 121 to 5, to vote any amount of money or number of men necessary to put down the rebellion. The five resisting members included four from the Slave States, and Ben. Wood, of New York. The Senate has expelled all Senators who, acquainted with the conspiracy, did not reveal it; has sanctioned a loan of 250,000,000 dollars at seven per cent., irredeemable for twenty years, and raises three-fifths by open loan, and two-fifths in Europe. The next mail ought to bring as important intelligence. It is suggested that the Federal Govern- ment intend to surmount the cotton difficulty for themselves by seizing Charleston or New Orleans, and so putting an end to the blockade.
