jSTo. 4 is at present probably only a reservoir for surplus water from 

 No. 1, wliich it is below, and only a short distance away. It is a turbid, 

 blue pool, about twenty feet in diameter, wliich spreads out into a shal- 

 lower gray basin, the entire dimensions being 80 by 150 feet. No steam 

 rises from it, and the water is cold. 



No. 5 is a light-blue spring, with a white basin about 20 feet in 

 diameter. It receives considerable water from No. 1, and has a tem- 

 perature of 1350 F. 



No. C. Indigo spring. — This is a dark blue boiling spring. It is trian- 

 gular in shape, measuring 20 by 25 feet. There are several points of 

 ebullition, and the temperature is lOG^i. The water outlet is lined with 

 lemon-yellow colored deposit. Back of this spring, and south of it, are 

 a number of fissures and steam vents. 



No. 7 is a collection of three small bubbling pools : a is white lined and 

 bubbles rapidly, but not violently; h is an oblong opening in broken 

 fragments of grav geyserite; c is a white basin. The temperatures are 

 Iti'JOF., 1250 F., and'lilloF. 



No. 8 is a rai)id bubbler, in a white basin 9 by 12 feet. 



No. 9 is near No. 8, and is a clear bubbler with two openings; tem- 

 perature 19()o. There are several other small ones near by. 



No. 10 indicates the i)Ositioii of two small holes, (5 inches each in diam- 

 eter, with temperatures of 194° and 195o. The water from them spreads 

 out on a red deposit.
