IN your remarks on p. 297 (July 27) on the above subject, you mention “the diversity of yield from farms in the same neighbourhood … due presumably to differences of shelter and aspect.” It is a remarkable thing that, so far as I know, nothing has ever been done to find out and publish the most suitable localities, as regards soil and climate, for orchard planting. It is a question of very great complexity, and can only be dealt with properly by officials appointed for that purpose; but its importance in fruit culture is so obvious that a considerable expenditure would be well repaid. Few people have any idea of the great climatic differences in localities within even a few hundreds of yards!
