KNOWLEDGE IS POWER : A VIEW OF THE PRODUCTIVE FORCES OP 

 MODERN SOCIETY, and the Result of Labor, Capital, and Skill. By CHARLES 

 KNIGHT. American edition, with Additions, by DAVID A. WELLS, Editor of 

 " Annual of Scientific Discovery," &c. With numerous Illustrations. 12mo, 

 cloth. $1.25. 



This work is eminently entitled to be ranked in that class, styled," BOOKS FOR THE PEOPLE." The 

 author is one of the most popular writers of the day. " Knowledge is Power " treats of those things 

 Which. " come home to the business and bosoms " of every man. It is remarkable for its fullness and 

 variety of information, and for the felicity and force with which the author applies his facts to his 

 reasoning. The facts and illustrations are drawn from almost every branch of skilful industry. 

 It is a work which the mechanic and artizan of every description will be sure to read with a RELISH. 



This is a work of rare merit, and touches many strings of importance with which society is linked 

 together. No work we have ever seen is better calculated to inspire and awaken inventive genius 

 in man than this. Almost every department of human labor is represented, and it contains a large 

 fund of useful information, condensed in a volume, every chapter of which is worth the cost of the 

 book. It would be an act of manifest injustice to the community for any editor to feel an indiffer- 

 ence about commending this volume to a reading public N. Y. CH. HERALD. 



The style is admirable, and the book itself is as full of information as an egg is of meat. JOURNAL. 



As teachers we know no better remuneration, than for them FIRST to buy this book and diligently 

 read it themselves; SECOND, to teach to their pupils the principles of industrial organization which 

 it contains, and of the facts by which it is illustrated. It is one of the merits of this book that its 

 facts will interest youthful minds and be retained to blossom hereafter into theories of which they 

 are now incapable. THIRD, endeavor to have a copy procured for the district library, that the parents 

 may read it, and the teachers reap fruit in the present generation. N. Y. TEACH EU. 



Contains a great amount of information, accompanied with numerous illustrations, 'rendering it ft 

 compendious history of the subjects upon which it treats. N. Y. COURIER AND INQUIRER. 



We commend the work as one of real value and profitable reading. ROCHESTER AMERICAN". 



This work is a rich repository of valuable information on various subjects, having a bearing on th 

 industrial and social interests of a community. PURITAN RECORDER. 



MY SCHOOLS ANT) SCHOOLMASTERS ; OR, THE STORY OF * 



EDUCATION. By HUGH MILLER, author of "Old Red Sandstone," "Footprints 

 of the Creator," " My First Impressions of England," etc. 12mo, cloth. $1.25. 



" This autobiography is quite worthy of the renowned author. His first attempts at literature, 

 and his career until he stood forth an acknowledged power among the philosophers and ecclesias- 

 tical leaders of his native land, are given without egotism, with a power and vivacity which arc 

 equally truthful and delightsome." PRESBYTKRI AN. 



" Hugh Miller is one of the most remarkable men of the age. Having risen from the humble walki 

 of life, and from the employment of a stone-cutter, to the highest rank among scientific men, every- 

 thing relating to his history possesses an interest which belongs to that of few living men. There ia 

 much even in his school-boy days which points to the man as he now is. The book has all the eas 

 and graphic power which is characteristic of his writings." NEW YORK OBSERVER. 



" This volume is a book for the ten thousand. It is embellished with an admirable likeness of 

 Hugh Miller, the stone mason his coat off and his sleeves rolled up with the implements of labor 

 in hand his form erect, and his eye bright and piercing. The biography of such a man will interest 

 every reader. It ia a living thing teaching a lesson of self-culture of immense value." PUILA^ 

 DELPHIA CHRISTIAN OBSERVER. 



" It is a portion of autobiography exquisitely told. He is a living proof that a single man may 

 contain within himself something more than all the books in the world, some unuttered word, if he 

 will look within and read. This is one of the best books we have had of late, and must have a 

 hearty welcome and a large circulation in America." LONDON CORRESP. N. Y. TRIBUNE. 



" It is a work of rare interest ; at times having the facination of a romance, and again suggesting 

 the profoundest views of education and of science. The ex-mason holds a graphic pen ; a quiet 

 humor runs through his pages ; he tells a story well, and some of his pictures of home life might 

 almost be classed with Wilson's." NEW YORK INDEPENDENT. 



" This autobiography is THE book for poor boys, and others who are struggling with poverty and 

 limited advantages ; and perhaps it is not too much to predict that in a few years it will become one 

 of the poor man's classics, filling a space on his scanty shelf next to the Autobiography of i'rauk- 

 liu." NEW ENGLAND FARMER. 



" Lovers of the romantic should not neglect the book, as it contains a narrative of tender passion 

 and happily reciprocated affection, which will be read with subdued emotion and unfailing interest."
