Rosecrans is of medium height and stout, not quite so tall as McCook, and not nearly so heavy. McCook is young, and very fleshy. Rousseau is by far the handsomest man in the army; tall and well-proportioned, but possibly a little too bulky. R. S. Granger is a little man, with a heavy, light sandy mustache. Wood is a small man, short and slim, with dark complexion, and black whiskers. Crittenden, the major-general, is a spare man, medium height, lank, common sort of face, well whiskered. Major-General Stanley, the cavalryman, is of good size, gentlemanly in bearing, light complexion, brown hair. McCook and Wood swear like pirates, and affect the rough-and-ready style. Rousseau is given to profanity somewhat, and blusters occasionally. Rosecrans indulges in an oath now and then; but is a member of the Catholic Church in good standing. Crittenden, I doubt not, swears like a trooper, and yet I have never heard him do so. He is a good drinker; and the same can be said of Rousseau. Rosecrans is an educated officer, who has rubbed much against the world, and has experience. Rousseau is brave, but knows little of military science. McCook is a chucklehead. Wood and Crittenden know how to blow their own horns exceedingly well. Major-General Thomas is tall, heavy, sedate; whiskers and head grayish. Puts on less style than any of those named, and is a gentlemanly, modest, reliable soldier. Rosecrans and McCook shave clean; Crittenden and Wood go the whole whisker; Thomas shaves the upper lip. Rosecrans' nose is large, and curves down; Rousseau's is large, and curves up; McCook has a weak nose, that would do no credit to a baby. Rosecrans' laugh is not one of the free, open, hearty kind; Rousseau has a good laugh, but shows poor teeth; McCook has a grin, which excites the suspicion that he is either still very green or deficient in the upper story.

22. Colonels Wilder and Funkhauser called. We had just disposed of a bottle of wine, when Colonel Harker made his appearance, and we entered forthwith upon another. Colonel Wilder expects to accomplish a great work with his mounted infantry. He is endeavoring to arm them with the Henry rifle, a gun which, with a slight twist of the wrist, will throw sixteen bullets in almost that many seconds. I have no doubt he will render his command very efficient and useful, for he has wonderful energy and nerve, and is, besides, sensible and practical. Colonel Harker is greatly disappointed because he was not confirmed as brigadier-general during the last session of Congress. He is certainly young enough to afford to wait; but he seems to fear that, after commanding a brigade for nine months, he may have to go back to a regiment. He feels, too, that, being a New Jersey man, commanding Ohio troops, neither State will take an interest in him, and render him that assistance which, under other circumstances, either of them might do. These gentlemen dined with me. Harker and Wilder expressed a high opinion of General Buell. Wilder says Gilbert is a d—d scoundrel, and responsible for the loss at Mumfordsville. Harker, however, defended Gilbert, and is the only man I have ever heard speak favorably of him.

The train coming from Nashville to-day was fired upon and four men wounded. Yesterday there was a force of the enemy along the whole south front of our picket line.

From the cook's tent, in the rear, comes a devotional refrain:

"I'm gui-en home, I'm gui-en home,
To d-i-e no mo'."

24. We are still pursuing the even tenor of our way on the fortifications. There are no indications of an advance. The army, however, is well equipped, in good spirits, and prepared to move at an hour's notice. Its confidence in Rosecrans is boundless, and whatever it may be required to do, it will, I doubt not, do with a will.

The conscript law, and that clause especially which provides for the granting of a limited number of furloughs, gives great satisfaction to the men. They not only feel that they will soon have help, but that if their conduct be good, there will be a fair chance for them to see home before the expiration of their term of enlistment. Hitherto they have been something like prisoners without hope.

26. Another little misfortune has occurred to our arms at Brentwood. The Twenty-second Wisconsin, numbering four hundred men, was captured by General Forrest. The rebels succeed admirably in gathering up and consolidating our scattered troops.

The Adjutant and others are having a concert in the next tent, and certainly laugh more over their own performance than singers do generally. They have just executed

"The foin ould Irish gintleman,"
