improvement projects, respectively. Tlie autiiors liave endeavored to make 

 the exercises and projects " cover as completely as is possible the important, 

 interesting, and practical farm problems of the country. . . . Each exercise 

 and home project has been tried out." Tables showing digestible nutrients and 

 fertilizing constitutents in common American foodstuffs, plant food contained 

 in common fertilizers, feeding standards, and a suggested list of typical home 

 projects are appended. 



Manual for the teaching of agriculture, home economics, and manual 

 training in the sixth grade, T. E. Browne {State Bd. Ed. [N. C], Agr. Bui. 1 

 (1918), pp. 42, figs. 5). — Instructions are given for carrying out projects in 

 Irish potato growing, poultry raising, tomato growing, and gardening, one of 

 which the pupil is to select as his laboratory work. Of the possible 100 points, 

 a weight of 70 is given to the production phase, and 30 points to each to the 

 manual training and domestic science or cooking phase. This makes it possi- 

 ble for the boy to meet his 100 points by completing the production and manual 

 training phases and for the girl by completing the production and cooking 

 phases. A weight of 60 for the textbook work and 40 for the project is con- 

 sidered a fair distribution. 



Manual for the teaching of agriculture, home economics, and manual 

 training in the seventh grade, T. E. Browne (State Bd. Ed. [N. C], Agr. Bui. 

 2 (1918), pp. 30, figs. 4). — This is the second of a series of bulletins to be issued 

 in accordance with the requirements of the law of 1917. It gives directions 

 for carrying out manual training, growing and cooking projects with com, 

 peanuts, and vegetables, and raising a pig. 



Soils and crops, J. G. Hosier (CMcago: Rand, McNally & Co., 1919, pp. 

 VIII +412, figs. 179). — This text for schools includes a study of the factors of 

 crop production and of the following crops, together with some of the underly- 

 ing principles and practices involved in their improvement : Cereals, legumes, 

 forage, fiber, tuber, root, and sugar crops, and broom corn, rape, and field beans. 

 A study outline and problems, practice work, and references for supplementary

Botany for agricultural students, J. N. Martin {New York: John Wiley £ 

 Sons, 1919, pp. X+585, figs. 4S8). — This book is intended for elementary courses 

 in botany, covering a year's work, in colleges and universities. 



In its preparation the aim has been to present the fundamental principles of 

 botany, with emphasis upon their practical application. The author holds 

 that in an elementary course in botany, regaixlless of the education the stu- 

 dent desires to obtain, the guiding aim of both recitation and laboratory work 

 should be to give the student a notion of the fundamental principles of botany. 

 A secondary aim should be to relate the subject to the student's major line of 

 work. 



The subject matter in this text consists of two parts, part 1 being devoted 

 to the study of structures and functions, chiefly of flowering plants, relating 

 theni to such agricultural subjects as farm crops, forestry, and horticulture and 

 to the more advanced courses in botany. Part 2 consists of a study of the kinds 

 of plants, with emphasis upon their evolutionary relationships and their eco- 

 nomic importance, and evolution, heredity, and plant breeding as related to the 

 improvement of plants. 



Farm horticulture, G. W. Hood (Netc York: Lea d Febiger, 1919, pp. 

 TI+S39, figs. 142). — This book has been written primarily as an elementary 

 text to meet the needs of the undergraduate collegiate students as well as 

 those who are studying agriculture in the secondary agricultural schools. It
