The Division of Entomology in the Canadian Department of Agriculture is now one of the largest entomological services in the entire world, second only to the Bureau of Entomology and Plant Quarantine of the United States Department of Agriculture. Its staff now comprises over 300 professional officers and its annual budget is in the neighborhood of $3,000,000. Entomology, in such settings is, in the main, economic entomology: ancillary to agriculture. Pursuing this idea to what seems its logical conclusion, the authorities in some parts of the world have attempted, sometimes with success, to break up the entomological body into a collection of subordinate units, each working under more or less specialized agricuImra1 direction; so that the entomologist becomes a member of an agricultural team, concentrating on some special objective. Such arrangements are fairly common in the old world. Outstanding examples in Great Britain are the Horticultural Research Station at East Malling and the Agricultural and Horticultural Research Station at Long Ashton.
