The work of the Northern Insect survey and of the Northern Biting Fly Program brought to light many interesting questions concerning the habits and ecology of northern insects and it seemed desirable to set up more detailed studies that would be continued for a number of years at a chosen site. Through the courtesy of Dr. G. Hattersley-Smith and of the Defence Research Board such a program has been established at Hazen Camp, on the northern shore of Lake Hazen, Ellesmere Island (81° 49′ N., 71° 18′ W.). D. R. Oliver spent seven weeks at Hazen Camp in 1961, and in 1962 a party of six entomologists, a nematologist and a botanist worked there for 2½ months, almost the whole of the growing season. A smaller group is continuing the work in 1963.
