Water is rising and bubbling, with occasional steam bulges 



and spurts. This is 57 minutes before the eruption. 

 Water still rising.

The first eruption ended 5 minutes after an eruption of the Fountain 

 began, which occurred 20 minutes after the Jet began. When the sec- 

 ond one was observed, the Fountain began nearly 27 minutes before the 

 Jet began to spout, and it ended before the eruption of the Jet ceased. 

 There is therefore, probably, no connection between the two geysers- 



No. 12 was spouting continuously during the first eruption of the Jet, 

 and during the second it was quiet; and in the eruptions noted by Pro- 

 fessor Comstock in 1873 the two ceased action almost simultaneously, so 

 that between these two also there is a lack of sympathy, although Pro- 

 fessor Bradley in 1872 thought there was sympathy between their action 

 and the Fountain. He says : 



I stood one morning upon the mound of Fountain Geyser, in the Lower Basin, whose 

 pool was filled to overflowing, and was watching a vehement steam jet a hundred 

 yards away, on the lower slopes of the terrace. Suddenly this ceased, and at the same 

 mstant Fountain commenced playing. * * * This continued for about 30 min- 

 utes, and then ceased rather abruptly; as suddenly the steam jet commenced again. 

 About 20 minutes later it ceased again, and a small pool [Jet Geyser] a few yards 

 from Fountain, which had been empty before the latter's eruption, but partially filled 

 by its overflow, immediately began to boil and spit water from 5 to 10 feet high, and 

 continued intermittently for a half hour or more. During its periods of moderate 

 boiling the steam jet opened again, but ceased when the boiling became more violent * 



This apparent sympathetic action was only a coincidence, as more ex- 

 tended observations have shown. 



No. 12. S2)asm Geyser. — This, which is rather a spouting spring than 

 a geyser, was named by Professor Comstock in 1873. It has a yellow, 

 rather shallow, basin 25 feet long by 12 feet wide. It has a gray edge^ 

 and is handsomely ornamented on the edge and in the basin. The water 

 Is spurted from a hole at one end and rarely attains a height over 2 or 

 3 feet. When seen on the 1st of October it was spurting continuously 

 from the time we arrived, about two o'clock, until we left, at half-past 

 four. On the 2d it was in action part of the time we were near it, and 

 part of the time it was quiet. The temperature in the basin was 170° F., 

 and in the spouting hole 184° F. It receives the overflow from the Jet 

 Geyser. 



No. 13. Clepsydra Geyser. — This geyser was named by Professor Com- 

 stock in 1873 from its fancied regularity. He says : 



Like the ancient water-clock of that name, it marks the passage of time by the dis- 

 charge of water, t 



It has a central cone which is 15 feet in length, 10 feet in width, and 

 3 feet in height. In this cone, which is beautifully beaded, the orifice is 

 about 2 by 3 feet. To the right of it, i. e., in the direction of the Fountain, 

 is a large yellow-lined orifice, which has an opening into the main cone,
