tainty in drilling. Three miles straight south from Sedan, the 
county-seat, is a pool known as the Hoffman pool. Oil is ob- 
tained there at from 1050 to 1250 feet; the wells range from 
20 to 256 barrels initial capacity, many of them making 75 
barrels after months of pumping. Two miles to the east, and 
from two to six miles south of the Hoffman field, is an area 
trending north and south, about two miles wide and reaching 
down to the state line, commonly known as the Blundell-Spur- 
lock area. This was the first developed in Chautauqua county 
outside the immediate environs of Peru; on the whole it has 
proved to be a rich field. Immediately south of Peru about 
three miles is another pool, developed during 1905, known as 
the Scott pool. There are nearly forty wells along a north- 
and-south line about two miles long, with dry wells on the east 
and light gas-wells on the west. There seems to be a north- 
and-south trend of gas territory between this and the Blundell- 
Spurlock pool. 
Production.—The production for the year 1905 was about 
twelve million barrels. The table given on a subsequent page 
shows the total production by months of the entire area, as 
bought by the Prairie Oil and Gas Company and according to 
its monthly report; it exhibits the total runs, daily average of 
the same; total deliveries to refineries, daily average of same; 
total put into tanks, daily average of same; and, finally, total 
stocks on hand at the end of the year and for each month dur- 
ing the year. 
To these should be added a small amount consumed py the 
independent refineries at Humboldt, Paola, Cherryvale, etc., 
and the still smaller amount used as fuel- and lubricating-oils, 
which may be estimated at from 100,000 to 125,000 barrels. 
It will be noticed that, beginning with July, the monthly 
runs exceeded one million barrels; and that for the last three 
months it exceeded one and one-third million; so that 1905 
turns.over the industry to the new year on a basis of more than 
sixteen million barrels annual production. Of this amount, 
much more than one-half came from the indian Territory; but 
at the present an exact division cannot be made. Presumably, 
however, not more than one-third of it came from Kansas. 
The extra development in the Indian Territory, as already 
explained, was due in part to stronger wells and less uncer- 
tainty in drilling. But another very important factor is the 
legal status of leases on Indian lands. The Secretary of the In-
