McClellan's army landed, and he is to be in command of all the troops. I congratulate all therein concerned about this new victory. Bleed, oh bleed, American people! Mr. Lincoln and consortes insisted that McClellan remain in command. Siste tandem carnifex!

Mr. Roebuck, M. P., the gentleman! About thirty years ago, when entering his public career as a member for Bath, Mr. Roebuck was publicly slapped in the face during the going on of the election. A few years ago Mr. Roebuck went to Vienna in the interests of some lucrative railroad or Lloyd speculation, and returned to England a fervent and devoted admirer of the Hapsburgs, and a reviler of all that once was sacred to the disciple of Jeremy Bentham.

General Halleck may become the savior of the country. I hope and ardently wish that it may be so, although his qualifications for it are of a rather doubtful nature. Gen. Halleck wrote a book on military science, as he wrote one on international laws, and both are laborious compilations of other people's labors and ideas. But perhaps Halleck, if not inspired, may become a regular, methodical captain. Such was Moreau.

Also, Gen. Halleck is not to take the field in person. I am told that it was so decided by Mr. Lincoln, against Halleck's wish. What an anomalous position of a commander of armies, who is not to see a field of battle! Such a position is a genuine, new American invention, but it ought not to be patented, at least not for the use of other nations. It is impossible to understand it, and it will puzzle every one having sound common sense.

Gen. Butler commits a mistake in taunting and teasing the French population and the French consul in New Orleans. When Butler was going there, Mr. Seward ought to have instructed him concerning our friendly relations with Louis Napoleon, and concerning the character of the French consul in New Orleans, who was not partial to secesh. There may be some secesh French, but the bulk, if well managed, would never take a decided position against us as long as we were on friendly terms with Louis Napoleon.

The President is indefatigable in his efforts to—save slavery, and to uphold the policy of the New York Herald.

It is said that General Hunter is recalled, and so was General Phelps from New Orleans; General Phelps could not coolly witness the sacrilegious massacre of the slaves. The inconceivable partiality of the President for McClellan may, after all, be possibly explained by the fact that Mr. Lincoln and Mr. Seward see in McClellan a—savior of slavery.

During two days' terrible fighting at Manassas, at Bull Run, and all around, Pope cut his way through, but the reinforcements from McClellan's army in Alexandria are slow in coming. McClellan and his few pets among the generals may not object to see Pope worsted. Such things happened in other armies, even almost under the eyes of Napoleon, as in the campaign on the Elbe, in 1813. Any one worth the name of a general, when he has no special position to guard, and hears the roar of cannon, by forced marches runs to the field of battle. Not any special orders, but the roar of cannon, attracted and directed Desaix to Marengo, and Mac Mahon to Magenta. The roar of cannon shook the air between Bull Run and Alexandria, and —— General McClellan and others had positive orders to run to the rescue of Pope.

I should not wonder if the President, enthusiasmed by this new exploit of McClellan, were to nominate him for his, the President's, eventual successor; Mr. Blair will back the nomination.

It is said that during these last weeks, Wallach, the editor of the unwashed Evening Star, is in continual intercourse with the President. Arcades ambo.
