DESCBIPTION. 



Ko. 6. Glen Sirring. — This, which is the largest spring of the group, is 

 the one marked Big Hot Basin on the map of 1872. It is a beautiful 

 gTeen basin 45J feet long, situated in a gulch at the foot of the hills 

 some distance back of the other springs of the group. It is irregular in 

 shape, but is about 20 to 30 feet wide. There is a central bowl, or basin, 

 measuring 4 by 8 feet, which is 6 feet deep. From this center the water 

 bulges at intervals which were not determined. On one of our visits 

 the basin surrounding it was empty, and at another time it was bulging 

 and the basin was full. It was at this time that the temperature of 

 160° F., given in the table, was obtained. When active there is a strong 

 overflow, which flows from the .spring in a beautiful deep-red trough- 

 like outlet bordered with rosette-like masses of gray, brown, and white 

 geyserite. The coloring in the basin of the spring is very handsome, 

 delicate tints of gray, pink, and yellow being intermingled. The border 

 around it is scalloped and ornamented with masses of deposit. 



No. 7. Broicn Sponge (Plate XXXIV). — This is the Brown Crater of 

 Bechler's 1872 map, and is a peculiar opening in the surface. It is best
