They must not be permitted to enter. Upon this point it is inexorable. It will permit no compunctious visitings of nature to shake its fell purpose.

The Northwest to Join Them.

I know all this sounds vastly like a joke; but The Crescent is lugubriously in earnest. In sooth, these Rebels are gentlemen of magnificent expectations. "Sir," remarked one of them, a judge, too, while conversing with me this very day, "in seven years, the Southern Confederacy will be the greatest and richest nation on earth. We shall have Cuba, Central America, Mexico, and every thing west of the Alleghanies. We are the natural market of the northwestern States, and they are bound to join us!"

Think of that, will you! Imagine Father Giddings, Carl Schurz, and Owen Lovejoy—the stanch Republican States of Wisconsin, Michigan, and even young Kansas—whose infant steps to Freedom were over the burning plowshare and through the martyr's blood—knocking for admission at the door of a Slave Confederacy! Is not this the very ecstasy of madness?

March 26.

That virtuous and lamented body, the Louisiana Convention, after a very turbulent session to-day, has adjourned until the 1st of November.

The Crescent is exercised at the presence here of "correspondents of northern papers, who indite real falsehoods and lies as coolly as they would eat a dinner at the Saint Charles." The Crescent's rhetoric is a little limping; but its watchfulness and patriotism are above all praise. The matter should certainly be attended to.

The Swamp—a Trip through Louisiana.

We are still enjoying the delights of summer. The air is fragrant with daffodils, violets, and roses, the buds of the sweet olive and the blossoms of the orange. I have just returned from a ride through the swamp—that great cesspool of this metropolis, which generates, with the recurrence of summer, the pestilence that walketh in darkness.

It is full of sights strange to northern eyes. The stagnant pools of black and green water harmonize with the tall, ghastly dead trees, from whose branches depend long fleeces of gray Spanish moss, with the effect of Gothic architecture. It is used in lounges and mattresses; but when streaming from the branches, in its native state, reminds one of the fantastic term which the Choctaw Indians apply to leaves—"tree-hair."
