THE current issue of Agricultural Progress (16, Pt. 1, 2s. 6d.), the official organ of the Agricultural Education Association, which is the most influential body of agricultural teachers and research workers in Great Britain, contains much interesting and instructive matter. The early days and later growth of the South-Eastern Agricultural College at Wye are described in the series dealing with the development of agricultural educational and research institutions, whilst the articles on the teaching of agriculture in schools, county instruction in farm machinery, and the educational value of tours for agricultural students, afford evidence of the real advances that are taking place at the present day on the practical side. Two particularly important topics are very fully dealt with. Mastitis disease, which causes serious losses to the milk industry, is discussed from the point of view of the veterinary surgeon, the cheesemaker and the bacteriologist. Methods of field laboratory diagnosis are explained. The other subject is afforestation, and while one author backs up his protest against the afforestation of farm land with numerous examples of the way in which the Forestry Commission has operated in Suffolk, one of the Forestry Commissioners puts forward the other side of the case. Other articles deal with such matters as the foot-rot diseases in cereals, manganese deficiency in relation to soils and crops, and the separation and analysis of soil clay fractions. A considerable space is devoted to book reviews. Agricultural Progress will in future be published twice yearly, in February and September.
