14 are so far fulure problems to us, but the most outstanding and urgent ones seem to me to be the following: 1. To fix the position of a certain number of »skridjökuls« in different regions and to control their variations from year to year. 2. To measure the movements of the these skridjökuls, at least in summer. 3. To study the climatological conditions of the glaciers and their neighbourhood by permanent or temporary meteorological stations in different heights. — These stations will give the exact rate of the decrease of temp- erature and the increase of precipitation with height. 4. To prepare detailed topographical maps of the glaciers, seleded as chief research objects, and their immediate surroundings. 5. To measure the ablation on the glacier surface in summer by means of selfrecording instruments. 6. To measure the run off of the glacier rivers in order to compare it with the assumed precipitaíion and ablation in the respective glacier regions.1) While making these investigations it should be borne in mind that it is wise to limit the research work to a certain number of selected glaciers and to obtain as satisfactory results as possible in each place. II. GLACIERS VISITED IN THE SUMMER 1930 With support from the »Náttúrufræðadeild menningarsjóðs Islands« the present author made excursions to some glaciers last summer for the purpose of fixing their present position, so that future changes might be measured. The equipment was quite insufficient, consisting only of a 20 m. cord with knots at 2 m. intervals, a compass and a camera. Measurements from fixing marks to the edge of the glacier by means of a cord have been practised a good deal 1) H. W. Ahlmann: Projet d’un programme de recherches gleciaires.
