Last December in Washington, in my report to the Board of Governors, some aspects of Institute financing were described, especially some of he major sources of support. Today I want to discuss with the Board a segment of Institute financing that, I believe, is little understood but with the essence of which each Governor, I think, should be familiar. I want to outline what the Institute does with the unrestricted funds that it obtains. Only by understanding the use of unrestricted funds can each of you expect to be effective in assisting your organization to acquire the unrestricted funds it needs to advance toward its objectives. The basic aim of the Arctic Institute is to encourage and support the acquisition of knowledge about the polar regions and to disseminate that knowledge. Anything that the Institute does should be toward that aim. In the financial year that ended on June 30, 1963 the Institute acquired a total of $118,000 that was free for use in any way the Institute desired. The money came from such items as contributions from governments, corporations, foundations, and individuals; interest and dividends; and gain on the sale of securities. It does not include $12,000 from membership dues and sales of publications because the auditors apply that income to reduce the cost of administration of Institute operations.
Reports investigations on Ice Island T-3 at approx 70-80 de- grees N, 110-140 degrees W, May 1958-Sept 1959. The North American 113a and Worden E-340 gravity meters were used for twice- daily measurements. Values of observed gravity, free air and Bouguer anomalies are tabulated, contoured, and interpreted. Gravity anomalies were found at 76-80 degrees N, and a gradient near 75 degrees N which indicates an increase in density of subbottom rocks toward the southwest. Bouguer anomaly values increased with distance from land, characteristic of normal ocean basins.
Some observations on permafrost distribution at a lake in the Mackenzie Delta, N.W.T., Canada

Reports investigations of the thawing effect of water on permafrost in northern Mackenzie District during Apr 1961. Holes were drilled under the center of a small, shallow lake with a mean bottom temperature higher than 32 degrees F and at various distances to the west of the lake. Hand probings were made near the edge of the lake, soil and water samples taken, ground temperatures measured, altitude and various terrain surveys made. It was found that the sediments below the center of the lake were unfrozen to bedrock; but the position of the permafrost table rose progressively toward shore and the thawing effect was confined to the ground lying under the lake. The thermal effect of the lake however, extended for some distance beyond.
Tundra rodents in a Late Pleistocene fauna from the Tofty placer district, central Alaska

Describes remains of the arctic ground squirrel, collared and brown lemmings, and the narrow-skulled vole collected 1956-1961 in or near the Sullivan mining pit. Topography, vegetation, and mining history are outlined, as are the stratigraphy and age of the unconsolidated deposits in which the fossils were found. The rodents, all typical tundra forms, are not now in the Tofty area which has been forested at least 6800 yr. Apparently, they represent the fauna of a colder climatic period during Wisconsin time.
Reports on concentrations of strontium-90, cerium-144, and promethium-147 in water samples collected 1959-1962, especially as indicating mass transport of ocean water. The 1959 Sr-90 fallout values were less than those reported from the northwestern Pacific and similar to values for the North Atlantic and mainland Alaska; but the 1960-62 values increased, in contrast to the other areas. No comparable increase was found in the Ce-144 and Pm-147 concentrations, but these radioisotopes may be removed from sea water during passage over shallow seas and analysis of sediment content would be enlightening.
Notes 1960-1963 investigations of these frost mounds, their plant succession, and use by mink. The pingos are described, and three types distinguished according to the plant com- munities they support, viz: grass, mixed vegetation type pingos have the greatest depth to permafrost, also other conditions suitable for mink natal dens.
