No. i37. Crater of the Castle Geyser, near view, from between it 

 and the Beautiful Hot Spring lying next the river. 



No. 438. Beautiful Hot Spring and orator of the Castle, same as 

 No. 205. 



No. 139. Crater of the Old Faithful, at the upper end and south- 

 ern end of the basin, so named from the regularity of its 

 eruptions, occurring once an hour with hut very Blight varia- 

 tions. (For views of the eruptions, see stereoscopic series, Nos. 

 540, 547.) It has built up a mound about twenty feet in height, 

 with some most beautiful cauliflower like formations, ex- 

 quisitely beaded, with thousands of pearls, and when wet after 

 the eruptions each one glistens and sparkles like the real 

 gem. The orifice is about three feet in diameter. 



Xos. 440, 441. Old Faithful in eruption; not as good as the ster- 

 eoscopic views, but still giving a good idea of the force and 

 grandeur of the uplift to such great height (150 feet) of so 

 large 1 a body of hot-water. 



No. 442. Crater of the 1>ee -Hive Geyser. On the opposite side of 

 the river from the Castle and Old Faithful. A very sym- 

 metrical cone, about five feet in height and six feet in di- 

 ameter at its base. It is most beautifully beaded all over 

 its exterior surface with small pearl-like drops of silica. Its 

 erupt ions are of great force, throwing a stream fully two 

 hundred feet in height, and holding it up with perfect steadi- 

 ness for a period of from ten to fifteen minutes. 



No. 443. Crater of the Giantess Gevser. It has a large, deep ori- 

 fice, twenty by twenty-five feet in diameter, and when empty 

 showing a depth of eighty feet. Our view represents it 

 nearly full, just previous to an eruption. In 1870 its erup- 

 tions were recorded by Langford as being over 200 feet in 

 height. 



No. 444. Crater of the Grand Geyser. Nearly opposite the Castle, 

 and so named from the great force and power it displays in 

 its eruptions, varying from 150 to 250 feet in height. For a 

 space of ten feet about the crater the surface is elegantly 

 adorned with beautifully- scalloped little reservoirs, filled with 

 the clear transparent waters from the geyser. 



Nos. 445, 44(5. A distant view of the Castle in eruption, from 

 across the river, near the Giantess, about 750 yards distant. 

 This eruption lasted fully two hours, and averaged 100 feet 

 in height; it was accompanied with a loud rumbling noise, 

 and shook the earth near by. In the foreground is one of 

 the small hot springs, so numerous throughout the basin. 



No. 447. Turban Gevser, adjoining the (hand, within a few feet, the 

 ornamentations about them being identical. The eruptions 

 are not very great, not more than twenty or thirty feet in 

 height. 



No. 448. The Grotto, a near view of the crater, showing the beading 

 and crystalline whiteness of the whole mass. (See Nos. 207, 

 2! IS.) 



No. 410. Hot Spring- Basin, similar to those in Nos. 205 and 415, but 

 most beautifully scalloped and beaded. Is about five feet in 

 diameter. Occasionally it overruns its basin, and then 

 recedes to a considerable depth, but never ejecting its waters 

 as violently as a geyser.
