 Periodiques des Glaciers, XIII m<i Rapport, 1912 ; by Charles 

 Rabot and P. L. Mercanton. Annales de Glaciologie, viii, 

 pp. 42-62, 1913. With Supplement, pp. 191-202.— Owing to the 

 unusual climatic conditions, the glaciers of the Swiss Alps 

 increased in volume during 1912 and more than compensated for 

 the decrease recorded in 1911. Of 52 glaciers noted, 2 undoubt- 

 edly and 9 probably advanced during the year, while 25 show 

 recession. The corresponding figures for 1911 based on 67 

 glaciers, are 1, 1, and 42 respectively. In the eastern Alps the 

 conditions for glacial studies were very unfavorable during 1912, 

 but such observations as were made indicate that while three 

 small glaciers advanced slightly, the tendency to decrease is still 

 maintained. The few glaciers measured in the Italian Alps are 

 with one exception receding. While certain of the glaciers about 

 Mont Blanc and the Massif du Pelvoux exhibit an increase of 

 mass above their snouts, the tendency to a general increase sug- 

 gested by the behavior of the glaciers in the French Alps during 

 1911 was not evident in 1912. L. Gaurier reports for the 

 Pyrenees that the ice masses in the basin Gave de Pau have for 

 several years shown indications of an increase in length and 

 volume. The glaciers of north Sweden continue to grow in 

 length. In Norway all glaciers in the Jotunheim mountains 

 exhibited decreases during 1911-12, varying from 0*2 to 29 

 meters. On the western and northern borders of Norway four 

 tongues of the Jostedalsbrae, two in the Okstind mountains and 

 one of the Svartis glaciers, have advanced ; 27 others have 

 receded. Observations of North American glaciers indicate 

 marked retreat of ice tongues on Mount Rainier during the 

 period 1909-1912. Recent surveys show a decrease in length of 

 the Nisqually glacier of 300 meters since 1885. The Alaskan 

 glaciers are in retreat and the grand Pacific glacier shows the 

 unprecedented decrease of 25 kilometers since 1879. During the 

 months of June and July, 1912, this glacier retreated more than 

 \\ kilometers. Scattered observations in Greenland indicate that 

 conditions tending to decrease of glaciers are prevalent. 



The reports of the International Glacier Commission are 

 becoming each year more valuable because of the increased 

 attention paid to the variation in the controlling climatic factors.
