able data as a foundation. There are several rocks on the moraine- 

 which bear marks or dates as old as 1890, but most of them are so 

 worn as to be almost illegible. We found one, however, near the 

 border moraine above referred to which, if it had not been moved, 

 indicated that in August, 1890, the snout was sixteen feet above a 

 certain mark. The distance from that mark to the snout in 

 August, 1898, was four hundred and fifty-two (452) feet, or an 

 average annual recession of fifty-six (56) feet, during the period of 

 eight years. There is reason to believe, however, that for a part 

 of this period the glacier remained more nearly stationary, and in 

 the remaining years made up for the deficiency by a much more 

 rapid melting away. 



The Asulkan Glacier being situated at the head of the valley of 

 the same name and about four miles distant from the Glacier House 

 is not nearly so easy of access for observation. Its neve is con- 

 nected with that of the Illecellewaet over the ridge which separates 

 them, so that while they flow into separate valleys they rise from 

 practically the same source. We are not aware that any work has 

 been done upon this glacier, as it is probably not visited by more 

 than a score of persons in the course of the year. The rapidly 

 descending stream from its foot, which is joined by another from 

 the glaciers in the immense amphitheatre to the east, passes through 

 a narrow caiion a quarter of a mile below the snout. In this caiion 

 there appeared to be no sign of glacial action, which would indicate 

 that the ice had extended behnv this point only before the formation 

 of the caiion. A very large moraine flanking the glacier on the 

 west also pointed to the fact that the ice had not receded materially 

 in recent years. 



The same methods were pursued here as in the case of the 

 Illecellewaet Glacier. A very large rock, the top of which was 

 smoothly glaciated, was chosen on the east side of the stream below 

 the glacier, and the test picture was taken, August 23, 1898 (PI. 

 VI). While it records the general outline of the ice, it does not 

 locate the snout, which seemed to be deeply buried in moraine. 

 Apart from thus fixing the position of the ice on this date, it was 

 impossible to draw any conclusions, as there are no previous records 

 with which to make comparisons.
