mable gas seemed to decrease as the pipe went down, while the 
pressure of the gas taken as a whole increased to near six 
pounds. I allowed it to escape for several days before giving 
it up, and then had the pipe pulled up after taking a bottle of 
the gas for Mr. Chamberlin. I am told by the well-digger that 
oe same kind of gas has been encountered in this vicinity be- 
ore. 
In view of the unusual nature of this gas, it is to be re- 
gretted that further investigation was thus cut off. 
IOWA. 
Natural gas occurs in Iowa, in rather small quantities, in 
the glacial drift. The Eighth Annual Report of the Iowa 
Geological Survey contains, in a report by A. G. Leonard,1‘8 
the following analysis of the gas obtained from wells at Daw- 
son, in Dallas county:

In this report Mr. Leonard expresses the opinion that the 
gas is simply the product of vegetable remains buried in drift. 
CALIFORNIA GAS. 
Few analyses have been published of California gases. We 
have found only three, published in several places, it is true, but 
still only three complete analyses. 
In a paper on the ‘‘Gas and Petroleum Yielding Formations 
of the Central Valley of California,’!49 W. L. Watts publishes 
two analyses of gas from wells at Stockton, Cal., made by 
Messrs. Price & Son, of San Francisco. The gases were col- 
lected in rubber bags:
