On July 27th a monument was built on a granite ledge 

 near the old trail between Paradise Park and Longmire's 

 Springs, and directly opposite the glacier's snout. This 

 monument was about ten feet to the left and above the 

 trail. The bearing from this point to the end of the 

 glacier was about N. 80° 30' W., magnetic. The angle 

 included between the end of the glacier and the right-hand 

 edge of Gibraltar Rock was 70° 53', and between the end 

 of the glacier and the summit of Tumtum Mountain, 

 ■ 54° 00'. It is hoped that this will help future observers 

 to determine something positive concerning the retreat 

 of the glacier's snout. 



The writer desires to express his thanks to Mr. James 

 Hutchinson, and other members of the Sierra Club, with- 

 out whose aid the measurements could not have been 

 made. Also, to Professor Harry Fielding Reid for his 

 kindness in suggesting methods of procedure, and in 

 criticising the results.
