OIL AND GAS IN THE MIDCONTINENTAL FIELD, 1907. 
During the year 1907 a very large development was pro- 
duced in the Midcontinental field. The oil development was 
confined almost entirely to the Indian Territory, now Okla- 
homa, but a large supply of gas was developed in Kansas. 
Likewise the total oil production in the Midcontinental field 
was produced very largely by Oklahoma. It is impractical to 
quote figures for each state, as the statistics obtainable are 
gathered in such a way that no discrimination is made. 
Oil.—The Prairie Oil and Gas Company (Standard) was 
the principal consumer of oil, although other interests, such as 
independent pipe-line companies, independent refineries and 
dealers in fuel-oil consumed a comparatively large amount. 
The accompanying table gives a summary of the monthly re- 
ports of the Prairie Oil and Gas Company, showing a total of 
35,756,366.76 barrels handled by this company. Much the 
greater part of this was used for refining purposes, so that only 
10,762,333.34 barrels were stored. This brings the total stor- 
age of the Prairie Oil and Gas Company at the close of 1907 up 
to the large sum of 33,703,367.74 barrels. To obtain the total 
production of the Midcontinental field, we must add to these 
figures the consumption by the independent refineries, the con- 
sumption as fuel-oil, and runs by the independent pipe-line 
companies. 
Nine independent refineries were in operation during the 
year. The one at Paola was bought by the Standard Oil Com- 
pany during the year; a few other smaller ones were operated 
irregularly, and these, when in full operation, had a capacity of 
only a few hundred barrels per day. The largest refineries are 
at Humboldt and Chanute. A conservative estimate of the 
total consumption of the independent refineries plus the total 
crude oil used for fuel is 2,309,500 barrels. 
The Gulf Pipe-line Company completed a line from the Glenn 
pool to the Gulf of Mexico and began pumping oil about Octo- 
ber 1. This company began storing oil in January. Before the 
pipe-line was built it shipped largely by rail, and even yet ships 
small quantities by rail from wells not yet connected with the 
pipe-line. A fair estimate of the business done by this com- 
pany during the year is 5,381,794 barrels, the output during 
the last half of December only being estimated. The Texas 
company also is shipping large quantities of oil from the Mid- 
continental field. It began shipping by rail in March; by Octo-
