WHAT SOCIAL CLASSES OWE TO EACH OTHER. By WILLIAM GRAHAM SUMNER, Professor of Political and Social Science in Yale College. 16mo, Cloth, 60 cents.

There is no page of the book that is not weighty with meaning. The argument that runs through it is like a chain, strongly welded, link on to link. * * * Prof. Sumner gives clear, pointed, and powerful utterance to much social and political wisdom. The teaching of the book is just of that sort which is most needed by the young America of to-day.-Boston Commonwealth.

The conclusions he reaches are substantially unanswerable. * * * No more important doctrine than this can well be proclaimed, and our country owes a debt of gratitude to whoever will proclaim it in the sturdy style of this book. We need not despair of the Republic while our young men are fed upon such meat as this. Whether they adopt his conclusions or not, they cannot fail to be stimulated by his reasoning.-The Nation, N.Y.

Prof. Sumner has selected a subject of great interest and importance, and has treated it with ingenuity, penetration, and originality, and in a plain, homely, pungent, and effective style.-Brooklyn Union.

His little book is full of excellent maxims of conduct formed on the manly principle of doing hard work and letting everybody have a fair chance. * * * These eleven short chapters are undoubtedly the ablest of recent contributions to matters on which much unprofitable ink is spent.--N.Y. Times.

This volume contains a most instructive discussion of certain economic questions which are of living interest touching upon the duties of the State to classes or individuals embraced in it.-Boston Globe.

The style is bright and racy, and the argument is allowed to lose none of its force by the use of technical terms. The book is suggestive, and will be found helpful to those who desire to reach correct conclusions on subjects of practical importance.-Christian at Work, N. Y.

Prof. Sumner has enforced in very few and very simple words some of the most important and most neglected principles of political and social economy; has exposed, with temperate but none the less telling sarcasm, the most absurd but not least popular crotchets of modern philanthropic enthusiasm.-Saturday Review, London.

; Or, Life in Dakota with General Custer. By Mrs. ELIZABETH B. CUSTER. With Portrait of General Custer. pp. 312. 12mo, Cloth, $1 50.

A book of adventure is interesting reading, especially when it is all true, as is the case with "Boots and Saddles." * * * She does not obtrude the fact that sunshine and solace went with her to tent and fort, but it inheres in her narrative none the less, and as a consequence "these simple annals of our daily life," as she calls them, are never dull nor uninteresting.-Evangelist, N. Y.

Mrs. Custer's book is in reality a bright and sunny sketch of the life of her late husband, who fell at the battle of " Little Big Horn." * * * After the war, when General Custer was sent to the Indian frontier, his wife was of the party, and she is able to give the minute story of her husband's varied career, since she was almost always near the scene of his adventures.-Brooklyn Union.

We have no hesitation in saying that no better or more satisfactory life of General Custer could have been written. Indeed, we may as well speak the thought that is in us, and say plainly that we know of no biographical work anywhere which we count better than this. * * * Surely the record of such experiences as these will be read with that keen interest which attaches only to strenuous human doings; as surely we are right in saying that such a story of truth and heroism as that here told will take a deeper hold upon the popular mind and heart than any work of fiction can. For the rest, the narrative is as vivacious and as lightly and trippingly given as that of any novel. It is enriched in every chapter with illustrative anecdotes and incidents, and here and there a little life story of pathetic interest is told as an episode.-N. Y. Commercial Advertiser.

It is a plain, straightforward story of the author's life on the plains of Dakota. Every member of a Western garrison will want to read this book; every person in the East who is interested in Western life will want to read it, too; and every girl or boy who has a healthy appetite for adventure will be sure to get it. It is bound to have an army of readers that few authors can expect.-Philadelphia Press.

These annals of daily life in the army are simple, yet interesting, and underneath all is discerned the love of a true woman ready for any sacrifice. She touches on themes little canvassed by the civilian, and makes a volume equally redolent of a loving devotion to an honored husband, and attractive as a picture of necessary duty by the soldier.-Commonwealth, Boston.

BY MARY TREAT, Author of "Chapters on Ants," &c. Illustrated. pp. 244. 12mo, Ornamental Cloth, $1 50.

Mrs. Treat roams through the fields in search of rare knowledge about birds, wasps, spiders, and those wonderful plants that entrap insects and thrive on their juices. Her originality in these researches is undoubted, and she adds a great deal to our stock of facts for use in the interpretation of nature. She has a pleasant style, and a winning knack of making disagreeable things seem otherwise. The pictures are many and good.- N.Y. Journal of Commerce.

A worthy tribute from a lover of nature to the animated world about her. It treats of birds, insects, plants that consume animals, and flowering plants. It has nearly seventy handsome illustrations, and the story is told in fascinating and clearly-expressed language. It is an admirable work with which to educate a family.-Boston Commonwealth.

To those who have given attention to the beauties of nature as developed in the winged world and the insect and floral branches, this little volume will be peculiarly grateful.-Albany Press.

Books on this subject are generally regarded by every one not professional scientists as dreadful bores. An exception must be made, however, in favor of Mrs. Mary Treat's "Home Studies in Nature." The only echoes of science between the two covers are the Latin names of birds, insects, and plants; all else are most curious and readable accounts of the doings of some creatures so tiny that they frequently are near us, and watching us, when we imagine ourselves alone. * * * This would be a capital book to give a bright-eyed boy or girl who complains that about home "there is nothing to look at." Adults, however will also enjoy the volume, and may make their eyesight keener by reading it.-N. Y. Herald.

The public should feel glad that occasionally a man or a woman finds highest pleasure in studying the ways and habits of nature, and publishing the result of such study to the world. This is what Mrs. Treat has done. * * * Her book is divided into four parts-observations on birds, habits of insects, plants that consume animals, and flowering plants. It is, moreover, helped by nearly seventy illustrations, which in a work of this character are of material assistance; for the great majority of readers are unfamiliar with the appearance of the birds, flowers, and insects, the habits of which are described. The author shows herself to be a keen, conscientious, and affectionate observer.--N. Y. Telegram.

Mrs. Treat can always command a delightful audience; for next to the pleasure of searching fields, woods, and streams for the beautiful or curious, it is charming to hear from so close an observer so much that is interesting and new, especially when all is told with vivacity and genuine enthusiasm. * * * The volume is finely illustrated, and its contents cannot fail to entertain the reader, young or old, who has learned, or is learning, about the busy world out-of-doors.--Worcester Daily Spy.

Suggestions as to their Manufacture and Use. By HENRY P. WELLS. Illustrated. pp. 364. Post 8vo, Illuminated Cloth, $2 50.

Mr. Wells has devoted more time and attention to the materials used in fly-fishing than any person we know of, and his experience is well set forth in this most valuable book. * * * The author is an amateur rod-maker who has experimented with every wood known to rod manufacturers, as well as with some that are not known to them, and therefore he is an undoubted authority on the subject. This chapter and the one following, which gives directions in rod-making, forms the most perfect treatise on rods extant. * * The book is one of great value, and will take its place as a standard authority on all points of which it treats, and we cannot commend it too highly.-Forest and Stream, N. Y.

Since Izaak Walton lingered over themes piscatorial, we have learned to expect, in all essays on the gentle art of angling, a certain daintiness and elegance of literary form as well as technical utility. Publisher and author have co-operated to meet these traditional requirements in "Fly-Rods and Fly-Tackle." * * * Mr. Wells's competence to expound the somewhat intricate principles and delicate processes of fly-fishing will be plain to any reader who himself has some practical acquaintance with the art discussed. The value of the author's instructions and suggestions is signally enhanced by their minuteness and lucidity.-N.Y. Sun.

A complete manual for the ambitious lover of fishing for trout. *** All lovers of fly-fishing should have Mr. Wells's book in their outfit for the sport that is near at hand.-Philadelphia Bulletin.

Mr. Wells reveals to us the mysteries of lines, leaders, and reels, rods, rod material, and rod-making. He lets us into the secret of making repairs, and gives all due directions for casting the fly. * * Moreover, Mr. Wells writes in an attractive style. There is a certain charm in the heartiness and grace wherewith he expresses his appreciation of those beauties of nature which the angler has so unlimited an opportunity of enjoying. Thus what may be called not only a technical, but also a scientific, knowledge of his subject is combined with a keen delight in hill, stream, and forest for the sake of the varied loveliness they display.-N.Y. Telegram.

A book of practical hints about the manufacture and use of anglers' gear. Fish-hooks, lines, leaders, rods and rod-making, repairs, flies and fly-fishing, are among the important subjects discussed with great fulness. The essay on "Casting the Fly" and "Miscellaneous Suggestions" are rich in points for beginners. It is to the latter, and not to the experts, that Mr. Wells modestly dedicates his work. His object is to supply precisely the kind of information of which he stood so much in need during his own novitiate.-N. Y. Journal of Commerce.
