PROF. R. G. STAPLETON, in his presidential address to Section M (Agriculture), stresses the importance of ley-farming in relation to the present-day needs of the nation, and in general he discusses the bearing of systems of farming on the formulation of a long-term agricultural policy. He urges that the needs of the nation must be made to govern the activities of the farmer. In considering national need, it is pointed out that account must be taken of future contingencies, as well as of present requirements. Thus, as well as producing an abundant supply of fresh food, our agricultural policy must take heed of war danger, fall in the population, and the influences of soil erosion overseas. The essential matter is therefore to maintain our acres in a fertile condition, while it is also desirable that we should conduct our farming in such a way as to make possible the maximum of flexibility in commodity production, and to make ourselves altogether less dependent upon imported feeding stuffs.
