Manual of Agriculture for Secondary Schools — Studies in Soils 

 and Crop Production. By D. O. Barto. Boston : D. C. Heath and Co. 

 1910. Pp. 89. Introduction by E. Davenport. 



"The purpose of this manual is to outline a course of study in agri- 

 culture, covering at least one year's work, which shall be of high school 

 grade, and shall offer training in sciences comparable to that furnished 

 by the other science courses in good high schools." The work is confined 

 to studies in soils and crop production, and is intended to accompany 

 text and bulletin study. Thirty-six exercises are given, with sufficient 

 test to develop the significance of the problems involved. The plan is well 

 worked out and the manual will prove most helpful to those who wish 

 laboratory guidance in secondary agriculture of high grade.
