was done by Prof. E. H..S. Bailey, of the University of Kansas, 
who published in 1895! a report of the analyses of samples of 
gas from seven of the best gas-producing localities in the state. 
The results are given in the following table:

These analyses have been widely copied in various reports 
from this and other states and have been accepted as com- 
pletely representative of all the gases from Kansas. They were 
carefully selected and did represent fairly the total gas supply 
then available, and are still typical of the better qualities of gas 
_ in the state as proven by the later work, but, nevertheless, the 
assumption that all the gas in this field has a similar composi- 
tion is no longer warranted. Since these analyses were made 
the development of gas-producing wells in the older portion of 
the field has been very great and gas has been found in so many 
new localities and so much further west that a new and more 
extensive set of analyses was very desirable. 
The present survey, while it has confirmed Professor Bailey’s 
results for the localities represented, has shown that a wide 
difference exists in the composition of the gas from different 
portions of the state, particularly in the outlying and more re- 
cently discovered fields. It also indicates that the variation in 
composition follows some regular order, which apparently has 
some relation to the geological structure. It shows also that 
while most of the gases of the state are of high fuel value, cer- 
tain ones are very low in combustible constituents and high in 
other more unusual components. The desirability of this sur- 
vey was made apparent by the analysis of a curious and diffi- 
cultly inflammable gas which was produced in extremely large 
quantities at Dexter, in Cowley county, in 1903. The following
