SOILS AND FERTILIZERS. By A. J. Macself. (Thornton Butterworth, Ltd.

6s. net.)

IN these shrewd times, when increased productivity is all the cry,' this book is worthy of a warm welcome. Without some knowledge of agricultural chemistry no worker in the soil, be he floriculturist, allotment holder, or farmer, can survey his operations in anything but the dimmest light ; nor, by conse- quence, can he expect a satisfactory return from his labour and his raw material. With admirable lucidity Mr. Macself has translated into the plainest of plain and engaging language, which all who dig may read, those: researches by which our great chemists have succeeded in. stimulating the earth to bring forth her increase. Investment in this little work should. declare a high dividend.
