to the monument is 280 meters, by aneroid. The gradient becomes progress- 

 ively steeper as one descends from the base of the ice-fall. 



No marks were made to record the extent of the other glaciers visited. 



Mount Hood, Oregon. — There are eight glaciers on this vol- 

 canic cone; all of them are steadily diminishing in size. The 

 Eliot glacier on the north side of the mountain is about four 

 kilometers (two and one-half miles) long and about 0.8 kilome- 

 ter (one-half mile) wide; and shows a marked recession in the 

 last three years. Before that the face was much steeper.' In 

 the central part of the glacier near the end the velocity of move- 

 ment has averaged about fifteen meters (fifty feet) a year since 

 1890. Coe glacier, which lies next to the Eliot on the west, is 

 about four kilometers (two and one-half miles) long and 0.4 

 kilometer (one-quarter mile) wide. {W. A. Langille.^ 



Illecellewaet Glacier, Selkirk Mountains, Canada. — As there is 

 at present no one on the committee representing the British col- 

 onies, I give what information I have concerning this glacier.^ 



Professor Charles E. Fay wrote me in 1895 that the glacier 

 had receded since 1890, and markedly since 1894. Photographs 

 taken by Messrs. Parker B. Field and Philip S. Abbot in 1895 

 and 1896, respectively, show that the recession continued last 

 year. 



There are prospects that more systematic observations of 

 some of the glaciers of the Pacific slope may be begun next 

 summer.
