Met Loomis; he had accompanied General Rosecrans and others to witness the trial of a machine, invented by Wilder, for tearing up railroad tracks and injuring the rails in such a manner as to render them worthless. Hitherto the rebels, when they have torn up our railroads, have placed the bars crosswise on a pile of ties, set fire to the latter, and so heated and bent the rails; but by heating them again they could be easily straightened and made good. Wilder's instrument twists them so they can not be used again.

The New York Herald, I observe, refers with great severity to General Hascall's administration of affairs in Indiana; saying that "to place such a brainless fool in a military command is not simply an error, it is a crime." This is grossly unjust. Hascall is not only a gallant soldier, but a man of education and excellent sense. He has been active, and possibly severe, in his opposition to treasonable organizations and notoriously disloyal men, whose influence was exerted to discourage enlistments and retard the enforcement of the draft. Unfortunately, in time of civil war, besides the great exigencies which arise to threaten the commonwealth, innumerable lesser evils gather like flies about an open wound, to annoy, irritate, and kill. Against these the law has made no adequate provision. The military must, therefore, often interpose for the public good, without waiting for legislative authority, or the slow processes of the civil law, just as the fireman must proceed to batter down the doors of a burning edifice, without stopping to obtain the owner's permission to enter and subdue the flames.

3. Our division was reviewed to-day. The spectators were numerous, numbering among other distinguished personages Generals Rosecrans, Thomas, Crittenden, Rousseau, Sheridan, and Wood. The weather was favorable, and the review a success. In the evening, a large party gathered at Negley's quarters, where lunch and punch were provided in abundance.

Generals Wood and Crittenden, of the Twenty-first Army Corps, claimed that I did not beat Wagner fairly in the horse-race the other day. I expressed a willingness to satisfy them that I could do so any day; and, further, that my horse could out-go any thing in the Twenty-first Corps. The upshot of the matter is that we have a race arranged for Friday afternoon at four o'clock.

The party was a merry one; gentlemen imbibed freely. General Rosecrans' face was as red as a beet; he had, however, been talking with ladies, and being a diffident man, was possibly blushing. Wood persisted that the Twenty-first Corps could not be beaten in a horse-race, and that Wagner's long-legged white was the most wonderful pacer he ever saw. Negley seemed possessed with the idea that every body was trying to escape, and that it was necessary for him to seize them by the arm and haul them back to the table; he seemed also to be laboring under the delusion that his guests would not drink unless he kept his eye on them, and forced them to do so. Lieutenant-Colonel Ducat, an Irishman of the Charles O'Malley school, insisted upon introducing me to the ladies, but fortunately I was sober enough to decline the invitation. Harker, late in the evening, thought he discovered a disposition on the part of others to play off on him; he felt in duty bound to empty a full tumbler, while they shirked by taking only half of one, which he affirmed was unfair and inexcusable. General Thomas, after sitting at his wine an hour, conversing the while with a lady, arose from the table evidently very much refreshed, and proceeded to make himself exceedingly agreeable. I never knew the old gentleman to be so affable, cordial, and complimentary before.

4. The guns have been reverberating in our front all day. I am told that Sheridan's division advanced on the Shelbyville road. It is probable that a part, if not the whole, of the firing is in his front.

5. Read the Autobiography of Peter Cartright. It is written in the language of the frontier, and presents a rough, strong, uneducated man, full of vanity, courage, and religious zeal. He never reached the full measure of dignity requisite to a minister of the Gospel. There are many amusing incidents in the volume, and many tales of adventures with sinners, in the cabin, on the road, and at camp meeting, in all of which Cartright gets the better of the sons of Belial, and triumphs in the Lord.

8. The One Hundred and Fourth Illinois, Colonel Moore, reported to me for duty, so that I have now four regiments and a battery. This Colonel Moore is the same who was in command at Hartsville, and whose regiment and brigade were captured by the ubiquitous John Morgan last winter. He has but recently returned from the South, where, for a time, he was confined in Libby prison.

The rebels are still prowling about our lines, but making no great demonstrations of power.

9. Governor (?) Billy Williams;, of Indiana, dined with me to-day; he resides in Warsaw, is a politician, a fair speaker, and an inveterate story teller.
