thus given continually increasing value. Each new edition shows 

 the perfecting touch of the author's hand. Messrs. Baudry & Cie., 

 the French correspondents of this firm, have cjmpleted a transla- 

 tion into French of the " Manual of Steam-engine and Boiler Tri- 

 als," by the same author, and will at once send it to press. They 

 are also translating (he " Manual of the Steam-engine," and ex- 

 pect to have that in type before the close of the year, under spe- 

 cial arrangements with author and publishers. 



— The number for March begins the seventh year of The Forum, 

 and for its seventh year several new enterprises in periodical work 

 are announced : first and foremost, the Silver Question. The 

 March number contains two papers on it — one by Mr. Bland, who 

 makes his best argument for silver, and the other by Mr. Leech, 

 director of the mint. In the following months The Forum, will 

 publish the most thorough discussion of this subject that has been 

 made, by the foremost writers of both continents. These articles 

 will be a special feature of forthcoming numbers. The Educa- 

 tional Investigation into the work of the public schools in the sev- 

 eral large cities of the Union has already been announced, and 

 Dr. J. M. Rice, the special student of the most advanced school- 

 work abi'oad, is now engaged in this task. His articles will begin 

 in an eai-ly number. In the March number are two noteworthy 

 educational articles — one by Mr. Clarence King, on -'The Edu- 

 cation of the Future," wherein he shows tbe narrow limitations of 

 all our teaching, and points out the yet undeveloped fields and 



methods, and the other by Professor John Earle on "The Study 

 of English." Another Hue of special work laid down by The 

 Forum is an investigation and discussion of Municipal Govern- 

 ment, which is confessedly the weak place in our whole govern- 

 mental system. The present number contains an investigation 

 made by Professor Peabody of Harvard into the municipal gov- 

 ernment of Dresden. The Progress of the most Important Arts 

 and Sciences will make a continuous feature of the coming vol- 

 umes of The Forum, such as Music, Sculpture, Painting, Arohi 

 feature, the Practical Application of Electricity, the Advance of 

 Preventive Medicine, the Progress of Astronomy. Another group 

 of subjects — old subjects that scientific progress makes of per- 

 petual interest —will be Good Country Roads, and How Well 

 they Pay; Scientific Agriculture and its Possibilities ; What the 

 Coming Man will Eat and How He will Cook it; and the like. 

 The especial development of The Forum will be in the direction of 

 original investigation by experts and authorities, into all classes 

 of subjects of the greatest concern to readers who wish to keep 

 abreast in their thought and lives with the world's progress; and 

 the aim is never to thresh over old straw. 



— A revised edition of Herbert Spencer's " Social Statics," the 

 book which has created such a stir among social reformers, wiU
