Introduction. 
ATURAL gas is a substance of great importance to a large 
proportion of the population of Kansas. Something 
like a third of the state is deriving its heat and light 
from this source and consequently the composition of gas 
should be of personal interest to every citizen of this portion of 
the state, since the value of the gas for all purposes is directly 
dependent upon its chemical composition. 
In the following report, the composition of Kansas natural 
gases has been taken up, and they have been compared with 
gases from other fields of the world.
