POPULAR SCIENCE MONTHLY. 



extreme of accuracy is not therefore sought, 

 but only such a degree as to insure that the 

 maximum accumulated error will be imper- 

 ceptible upon the maps. The results are ar- 

 ranged in chapters by geographical groups, 

 and as an introduction to each chapter there 

 is given a description of the work, outlining 

 the methods employed and instruments used. 

 The groups into which the work is divided 

 are roughly as follows : New England, the 

 Middle Atlantic States, the Southern Appa- 

 lachian Region, some of the North Middle 

 States, the Black Hills of South Dakota, 

 Aspen, Colorado, and portions of California, 

 the plateau region of New Mexico and Ari- 

 zona, Texas, Wyoming, Montana, Idaho, and 

 Kansas. There are a number of triangrula- 

 tion maps which illustrate the work done in 

 the various groups. 



The second volume of Prof. Wiley's Prin- 

 ciples and Practice of Agricultural Analysis 

 (Chemical Publishing Company, Easton, Pa., 

 $2) is devoted to fertilizers. In the first 

 three divisions the determination of phos- 

 phoric acid, nitrogen, and potash is de- 

 scribed, the official methods and a number 

 of other processes being given in each case. 

 The fourth and concluding part is devoted to 

 the examination of miscellaneous fertilizers, 

 some of mineral and others of organic origin. 

 The general principles of fertilizer manufac- 

 ture and application have been presented, in 

 so far as they seemed to the author to throw 

 light on the rational method of examination 

 and analysis. A list of authorities cited is 

 given at the end of each division of the vol- 

 ume, and there are seventeen figures of ap- 

 paratus.
