Read the account of the entrance into Paris, (pages 71 and 72,) and see if it does not take you back to our entering it, a year and more ago; and to our night at Dr. Matherson's brick house, at the head of the street, where we went for good quarters, thinking him a rebel, and wishing him out of our room before we settled ourselves for the evening, until he asked us if we knew Captain Nott, and shewed us that he knew, and was trusted by him; and what a cozy evening we passed with them, in spite of the bitter cold weather? We knew we were with a friend, and he did not spare his wood-pile in entertaining us. How graphic is the description of the freezing fast to the ground of the citizens, when they first see us coming into a town (making it always look like Sunday.) Read, too, of the Obion bottom--which was less muddy, but not more pleasant, to Captain Nott than to us--and of the wild confusion of single-rank cavalry when surprised; and of Bischoff's holding the Captain's stirrup under fire;--how like Hover, and the "_Vierte Missouri_," that!--and of Bischoff's gamey little black horse, bringing him through a tight place, just as Miss Pussy has done for you. And the skirmish, over the piano, with Miss Ayres; how like it is to what I've so often seen from you and the other young ones of the staff. It seems at first rather odd that a book originally written for school-girls, should be so exactly the book which is most interesting to men--even to those who have served--but it is precisely those little details, which one would think of writing only for children, which give to all the clearest idea of the realities of military life, and which best recall the daily pleasures, trials and anxieties of a campaign, when graver events have dimmed our recollection of them. I am sure that I am sending you material for a few hours pleasant reading in camp, and I trust to Captain Nott, to turn your memory back to the companionship and the incidents of the months which we passed together, in the valley of the Obion River. Very truly, yours, GEORGE E. WARING, JR. To Capt. HUNN HANSON, A. D. C. H'd Q'rs 16th Army Corps, Mobile Bay. _New York Evening Post._ A GOOD BOOK AND A GOOD DEED.
