 Is funnel-shaped, tapering down to a mere aperture, with the thin 

 scalloped rim projecting over the water all around for several inches. 

 Some have no water flowing from them 5 others send forth a stream 

 two feet wide and six inches deep. These springs vary in temperature 

 all the way from. 197° to 140^. About half of the springs were not 

 considered worthy of attention and are not located on the chart. In 

 the lower portions of this group,-there is one of the handsomest foun- 



tain-springs. The basin is most elegantly scalloped, nearly circular, 

 25 feet in diameter, with vertical sides to an unknown depth. The 

 entire mass of the water is at times most violently agitated, and, over- 

 flowing the sides of the basin, passes oft* in a kind of terrace pools or 

 reservoirs to the main stream, i)roducing a system of architecture out 

 of silica similar to that of the calcareous springs on Gardiner's Kiver.

 shown. Near this fountain is one of the elevated craters, which we
