CAMBRIDGE AGRICULTURAL MONOGRAPHS
General Editors: T. B. Wood, M.A., Draper’s Professor of Agriculture in the University of Cambridge, and E. J. Russell, D.Sc., Director of the Rothamsted Experimental Station, Harpenden, Herts.
Each volume of this series will contain a summary of the present position on some particular aspect or branch of agricultural science by an expert of acknowledged authority.
The treatment will be critical and impartial, and sufficiently detailed on all points of fundamental importance to be of use alike to all readers, but especially to those who are not in touch with an institution possessing a well equipped reference library. Full references will be given, and a bibliography attached for the benefit of those who wish to follow up any particular point.
The following volumes are in preparation:
- The Strength of Wheat Flour. By Professor T. B. Wood, M.A.
- The Constitution of the Soil. By E. J. Russell, D.Sc.
- Disease Resistance. By R. H. Biffen, M.A., F.R.S., Professor of Agricultural Botany in the University of Cambridge.
- Poisonous Plants. By H. C. Long.
