"There never has been a more interesting writer in the field of juvenile literature than Mr. W. T. ADAMS, who, under his well-known pseudonym, is known and admired by every boy and girl in the country, and by thousands who have long since passed the boundaries of youth, yet who remember with pleasure the genial, interesting pen that did so much to interest, instruct, and entertain their younger years. 'The Blue and the Gray' is a title that is sufficiently indicative of the nature and spirit of the latest series, while the name of _Oliver Optic_ is sufficient warrant of the absorbing style of narrative. This series is as bright and entertaining as any work that Mr. ADAMS has yet put forth, and will be as eagerly perused as any that has borne his name. It would not be fair to the prospective reader to deprive him of the zest which comes from the unexpected by entering into a synopsis of the story. A word, however, should be said in regard to the beauty and appropriateness of the binding, which makes it a most attractive volume."--_Boston Budget._ Woodville Stories. By OLIVER OPTIC.

They were really refreshing, even to us. There is much in them which is calculated to inspire a generous, healthy ambition, and to make distasteful all reading tending to stimulate base desires."--_Fitchburg Reveille._ The Starry Flag Series. By OLIVER OPTIC. In six volumes. Illustrated. Any volume sold separately. Price per volume, $1.25. 1. The Starry Flag; OR, THE YOUNG FISHERMAN OF CAPE ANN. 2.

"Mr. ADAMS, the celebrated and popular writer, familiarly known as OLIVER OPTIC, seems to have inexhaustible funds for weaving together the virtues of life; and, notwithstanding he has written scores of books, the same freshness and novelty run through them all. Some people think the sensational element predominates. Perhaps it does. But a book for young people needs this, and so long as good sentiments are inculcated such books ought to be read."
