During the summer of 1905, the writer, as a memberof the Sierra Clubs Outing to Paradise Park on thesouth slopes of this mountain, had the opportunity ofmaking a few measurements of the motion of the Nis- * This article appeared in Zeitschrift fur Gletscherkunde, I.

The positionof the end of the glacier was determined, and other ofits characteristics noted, in the hope that future observersmay be able to determine the changes that take place astime goes on. The Nisqually Glacier takes its rise on the southernrim of the crater, and for the first three miles of its coursehas a direct southerly trend. The eastern side of itstrough is formed by a high conspicuous mass of rockknown as Gibraltar, and the western side by a relativelylow rocky spur separating it from the next large glacierin that direction, the Kautz. Within the first three milesthe main neve stream makes a total descent of about 8,000feet, and the surface is broken by enormous ice-falls andfaults. The average slope in this part is therefore aboutthirty degrees, and the av
