ubout whose composition aiul ilistrilMition he ivached iniportaiit foiu'lu- 

 sions; the relations of suli)hiir to the gravity of California oils; and the 

 application of his conclusions on associated waters to the problem of the 

 salt domes in the Gulf Coastal Plain. His experience also with gas wells 

 in Ohio and in the mid-continent field during the open season of 1918 

 prepared him for writing the interesting paper on helium in the National 

 (ieographic Magazine and the bulletin now in press with the United 

 States Geological Survey. 



Early last autumn he obtained leave of absence from the Survey in 

 order to undertake exploration work for oil in the Mulatas Eiver region 

 of Colombia. He had successfully completed his engagement and was 

 on his way out in a native boat Avhen, on crossing the bar, the accident 

 happened which, to our inexpressible sorrow, ended a career of unusual 

 promise.

 ful selection of his college courses gave him this characteristic all 

 tlirough his life. Of accurate scholarship and a patient and faithful 

 oliserver, he brought to 1)ear on liis prol)lenis reasoning ability of a liigh 

 order.
