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



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

 appearance also was much the same. 



The 



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 temperature 

 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. 196 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.
