This Survey, which, under the directorship of Mr. Gordon Manley, had made substantial progress until the war intervened, is to be resumed during the autumn of 1946. For a time the principal aim will again be to secure representative data relating to the occurrence of snow-cover at different altitudes in the various upland districts over the period October to June. To this end the Society is fortunate in having already been promised the help not only of a number of pre-war participators in the Survey but also of the Meteorological Office, Air Ministry. By the courtesy of the Director, Sir Nelson Johnson, records of the daily incidence of snow-cover (and where possible of its depth) at about 55 high-level meteorological stations are to be supplied to us month by month. In addition, Dr. J. Glasspoole of the British Climatology Division has suggested that a considerable number of the regular contributors to the official publication British Rainfall whose gauges are situated at altitudes of not less than 500 feet should be invited to co-operate. Dr W. A. Harwood, Superintendent of the Meteorological Office at Edinburgh, has kindly agreed to allow that office to be used as a clearing house for Scottish records, as before the war.

Work on the Fröya Gletscher, N.E. Greenland, appears to substantiate the evidence already brought forward for the irregular flow of glaciers over short periods. It appears possible to correlate the daily temperature regime with the flow of some “polar glaciers.” The distribution of thrust planes seems to have no noticeable effect on the flow. It is suggested that Block-Schollen movement may underlie the jerky motion of some of even the slower moving glaciers. A subglacial stream bed on the Skille Gletscher was explored from the snout for a distance of 500 m. It is estimated that at the farthest point the ice was 76 m. thick. There appears to be good observational evidence for de Martonne’s theory of medial moraines extending to the bed of the glacier.

In the years immediately preceding the war more work on the causes of avalanches was done in Switzerland than in any other country. We in this country were kept well posted in the progress of the work by the willing cooperation of the Swiss and their permission for us to visit their avalanche research station on the Weissfluhjoch.
