The following is a summary of the Thirteenth Annual Report 
of the International Committee on Glaciers.’ 
REPORT ON GLACIERS FOR 1907 
The greater number of the glaciers of which we have any informa- 
tion are retreating; the glaciers of the Scandinavian Alps alone are 
entering a period of advance; this advance, which started some 
years ago in the Jostedal, became fairly general in 1907. 
Swiss Alps.—The retreat is general, but nevertheless it is not so 
strong as during the preceding years, which is probably due to 
changes in meteorological conditions. Of the fifty glaciers observed 
only one, the Glacier de Vorab, in the basin of the Rhine, has shown 
any marked growth. It advanced 133 meters between 1904 and 1907. 
Eastern Alps.—Of the twenty-five glaciers observed in 1906-7, 
twenty-four are retreating and one is stationary; therefore the slight 
advance indicated by some glaciers in 1905 has given way to a 
general retreat.4 
Italian Alps.—Observations on glaciers on the south side of 
Mont Blanc, and in the Lombard and the Venetian Alps, show a 
retreat more or less marked.° 
French Alps.—Measurements of the amount of snowfall in the 
neighborhood of Chamonix show that in the winter of 1906-7 the 
quantity of snow which fell was 20 to 25 per cent. greater than for 
many years past. This region seems to be passing through a snowy 
period; nevertheless the glaciers themselves are still retreating, and 
we shall probably have to wait many years before the heavy snowfall
