ON METEOROLOGY 



ELEMENTARY METEOROLOGY . . . .11.50 



By FRANK WALDO, Ph.D., late Junior Professor in 



the United States Signal Service 



IN this book, embodying the latest phases of the science, and 

 the most approved methods of teaching, the treatment, 

 as far as practicable, is inductive. The fact that meteor- 

 ology is largely an observational study is kept constantly in 

 mind. The student is introduced to rational methods of 

 investigation, and taught to observe weather conditions, to 

 account intelligently for successive changes in the weather, and 

 to make intelligent predictions for himself. Special chapters 

 are devoted to the meteorology of the United States, in which 

 the work of the Weather Bureau is clearly explained. The 

 charts and illustrations are an important feature. 



OBSERVATIONS AND EXERCISES ON THE 



WEATHER $0.30 



By JAMES A. PRICE, A.M., Instructor in Physiography 

 in High School, Fort Wayne, Ind. 



THIS laboratory manual is intended to supplement the 

 recitation work in physical geography and meteorology 

 in secondary schools. It consists of a blank weather 

 record covering forty days, to be filled in by the pupil from his 

 own observations of the thermometer, barometer, hygrometer, 

 weather gauge, clouds, winds, etc. Following these tables 

 is a series of ingeniously devised exercises whereby the pupil, 

 from the observation and study of his weather record, is led 

 to deduce many of the general principles of meteorology. 

 The instruments necessary for the observations are few and 

 inexpensive.
