gravity scale was adopted. Under this regulation, oil testing 
32° B., or more, was given the top price, and a decrease of ten 
cents per barrel for each degree, or five cents for each half- 
degree, was put upon the lower grades of oil. Gravity tests 
were made by the gager and were strictly enforced, often a 
shade of one-tenth degree causing a difference of five cents per 
barrel. 
A portion of the oil from Montgomery county, all of the oil 
from Chautauqua county in Kansas, and practically all from 
the Indian Territory-Oklahoma field, tests 32° B. or more, 
some of it reaching as high as 37° B. or 38° B. Almost 
all the remaining Kansas oil tests below 32° B. Although 
a penalty of five cents for each half-degree was imposed on oil 
below 32° B., yet a corresponding increase was not made for 
that above 32° B., so that wells producing oil testing from 35° 
B. to 38° B. have never been more profitable than they would 
have been had their product been barely above 32° B. 
Future Developments.—The success attending present op- 
erations in the Indian Territory is so great that future devel- 
opment will probably increase over the present production. 
Should the price of oil start upward with a fair promise of 
reaching one dollar per barrel, almost every leaseholder in the 
oil region would begin drilling. Under such circumstances it 
is difficult to tell what the result would be. Could we have an- 
other year of such prices, with a demand for the entire produc- 
tion, it would not be surprising if the field should reach a 
capacity anywhere from 75,000 to 100,000 barrels per day. 
OIL AND GAS IN THE MIDCONTINENTAL FIELD, 1906. 
The production of oil and gas in the Midcontinental field was 
much greater in 1906 than in any previous year. The oil was 
bought principally by the Prairie Oil and Gas Company, the 
Standard Oil Company in Kansas. At present there are nine 
independent refineries in Kansas and one in Indian Territory, 
but their consumption was small, due in part to their small 
size and in part to the fact that several of them did not begin 
operation until late in the year. A considerable amount of oil 
was used for fuel and was shipped to many places here and 
there over the state. One producer, C. A. Stannard, operated 
a system of tank-cars and supplied customers in western and 
central Kansas with a comparatively large amount of crude oil.
