THE AMERICAN NATURALIST. [Vol. XXXVIII. 



fication of soils ; Crossing corn ; Emergencies ; Removing ink from 

 white goods ; To make liquid yeast ; Chicory in coffee ; Cash ac- 

 count ; Tent caterpillars ; Planting trees ; Farm gate lesson ; Sewed 

 seam ; Overhand patch ; Three-cornered darn ; Cleft grafting. 

 These exercises are arranged somewhat in the order of difficulty and 

 in related groups, but the extent to which they shall elucidate princi- 

 ples or develop general ideas must very largely depend upon the 

 teacher. If skilfully incorporated with other work and their bear- 

 ings broadly discussed many of these exercises would have real 

 educational value in fitting pupils to meet intelligently the actual 

 problems of rural life. 



The text-book proceeds in a more orderly way, establishing gen- 

 eral principles and showing their application to problems of soil, 

 culture, protection, selection, stock-raising and dairying. Sugges- 

 tions for profitable observations or experiments are freely introduced. 

 The illustrations are of unusual excellence, and the style clear and 

 direct. Such a book cannot fail to advance the best interests of 

 practical education in much needed directions. Both books might 

 well be used together.
