Contains chronological account of events May-Nov. 1952 on Banks Island and mainland. The writer and A. Macpherson (q.v.) made preliminary soundings in harbors on south, west, and north coasts of the island and topographic and geologic notes on coastline and interior, collected bird, mammal, and plant specimens, and excavated four Thule houses. Canoe trip from De Salis Bay clockwise around the island was stopped by ice at Castel Bay on the north coast. Overland trips were made between Castel Bay, Storkerson Bay, Sachs Harbour, and De Salis Bay. Twelve new place names, approved by the Canadian Board on Geographical Names and used on map, are listed with brief notes.
Distribution of arctic lakes is noted and the literature reviewed. General problems in arctic limnology include thermal and trophic classifications, water circulation, productivity as compared with arctic marine waters, and comparison of arctic and alpine lakes. Future research programs should comprise a reconnaissance of lakes in the Canadian Arctic, intensive investigation of selected lakes and a river, expansion of Ungava work, and general studies on distribution of fresh-water fish. Cooperation between limnologists, plant ecologists, and geologists is urged.
Contains an historical account of past outbreaks of enteric diseases in arctic and subarctic Alaska. Only those caused by the Gram-negative bacteria of the genera Salmonella and Shigella are considered. Contaminated water supplies and inadequate sewage disposal have been the major causes of epidemics. 206 cases of typhoid fever are recorded for the period 1807-1952, and 230 cases of bacillary dysentery for the period 1937-51, with rates of fatalities, and type of infective agent, when known. This is revision of paper presented at Third Alaskan Science Conference, 1952. Author is Asst. Director, Public Health, Laboratories, Alaska Dept. of Health, Anchorage.
Five expeditions are described: those of Binney 1923 and 1924, Glen 1935-36, and Hartog 1949 (in which the writer took part) and 1951. Binney's expeditions were important for geographical discovery, while those of Glen and Hartog pursued more detailed work in geomorphology, glaciology, meteorology, and surveying. Few results of Hartog's work are yet published. Earlier expeditions of other origin are briefly noted.
