DESCEIPTIQN. 



to 5 are on the south side of the ravine, and are the 



Springs Nos. 1 

 first met with on coming from the White Dome. They are at the foot 

 of the hills in very marshy ground. Besides these there are others, as 

 the map indicates, but it was impossible to reach them on account of 

 the treacherous nature of the soil. 



Nos. 6 to 11 form a cluster on the opposite or north side of the valley 

 or ravine. They are situated on a mound of hard deposit, on which 

 Ho. 6 is the central and most important spring. 



ISTo. 6 has a beautiful basin, 10 by 15 feet, of irregular shape, in which 

 the water has a dark-green tint. The rim extends over the spring in 

 great scallops, on which the water stands to a depth of half an inch or 

 so. This is white and yellow, and forms an outer basin 3 to 4 inches 

 above the general level outside. The spring constantly bubbles and 

 boils at one end and sends the water in waves over the scalloi:)ed rim. 

 The temperature was 201° F. 



No. 9. Bead Geyser is a spouting geyser with a beautifully-beaded tube. 

 No data were obtained as to the height, duration, or interval, as our 

 stay was too short to allow of much time being devoted to it. 



No. 11 is a spouting spring on the water-way from No. 6. It has a 

 beaded flat basin. 



No. 12. Pinic Gone Geyser. — This is a beautiful rose-tinted cone 18 inches 

 in height and about 5 feet in diameter. The orifice is round, measuring 

 2 feet in diameter. It is beautifully beaded, and the cauliflower-like 

 formation is strong evidence that it has periods of eruption. It has 

 never been seen in action, and therefore nothing is known as to its in-
