11; and Cameron No. 1, all of which flowed over 100 barrels in the 
first twenty-four hours. 
Of these, the Davis No. 2 produced 2,200 barrels per day; the Davis 
No. 4, 1500 barrels during the first twenty-four hours; the A. M. 
Smith No. 3, 2,800 barrels, and the Matthew Taylor No. 3, 2,300 barrels 
in the same length of time. The largest well in the field w T as the Cam- 
eron No. 1, which at first produced 50 barrels per day, but after a few 
days reached 140 to 175 barrels per hour. May 31, 1886, the field con- 
tained 16 producing wells, the list of which, according to the Wash- 
ington Reporter, is as follows:

Some of the wells, including those on the Davis, Willetts, and neigh- 
boring farms, have maintained their production wonderfully, and 
l hese farms si ill have several producing wells. After fifteen years the 
William Smith No. 3 produced 7 barrels per day. The production of 
the Washington field for L887 was estimated at 2,S59,344 barrels, or 
7,800 barrels per day. For 1SSS it was 2,322,189.73 barrels. Most of 
the old wells have, however, run dry and have been abandoned, and 
those still existing are gradually disappearing. 
Besides the Gantz and Fifty-foot sands the Gordon has yielded oil in 
a few wells in the Washington field and the Fifth sand in several. The 
deeper sands have not yet been prospected, but they would seem to 
offer a field worth testing. As explained on page 51, the Big Injun 
sand proved productive in the Manifold and Willetts No. 11 wells — 
hence the name Manifold sand. The pocket of oil in that sand was, 
however, a very local one. 
One characteristic of the Washington field is that it was worked by 
a great number of small operators. At the time the excitement was at
