No. 15. T. 216° C. 500 feet west of No. 14. 



This fumarole was on the same general line of craters as No. 14. The 

 appearance also was much the same. 



No. 16. T. 147° C. 200 feet north of No. 15. 



This one was on the same general line of activity as Nos. 14 and 15, 

 but it was a steamer. The gases were very wet, and the ternperature 

 was only 147° C. The bright orange and red deposits were conspicuous.

FUMAROLE 11. 



Temperature 196° C. at the surface; 171° C. three feet down; 191° C. 



six feet down. 



No. 17. T. 190° C. 100 feet west of No. 16. 



This fumarole was on the same line of activity as Nos. 14, 15 and 16. 

 It was also a steamer, similar to No. 16. The instrument recorded 

 only 196° C. at the surface of the ground. 



No. 18. T. 264° C. 150 feet northwest of No. 17. 



This fumarole was on the same lines as Nos. 14, 15, 16 and 17. It 

 was a small theater of hot small holes, with characteristic brown baked 

 surface crust. We recorded two temperatures from it; one 264° C. and 

 the other 250° C. The vents were merely small irregular cracks, neither 

 depressed nor elevated above the general level of the Valley floor.
