conclusively proved the supposition that an anticlinal undoubtedly exists 
in the rocks down to the Berea but also that it even becomes more 
pronounced with depth. Of course, due allowance must be made for 
thickening of some of the formations. 
Here, as in the Mundy-Fifield well, the Berea proved to be a small 
yielder of brine, perhaps 25 or 30 barrels per day, and of gas. Drilling 
was continued with the idea of going on down to the Dundee, supposed 
to be 900-1000 feet below. At 2305 feet the Traverse limestone was 
entered and oil of (lie finest grade was struck at 2317 feet in a sandy or 
cherty limestone. The so-called “sand,” since called the “Saginaw 
Sand,” was very thin, being probably not much more than two feet. 
The well made two flows of some 40 to 50 barrels of oil altogether. 
The indications were that a 25 to 30 barrel wel 1 had been struck. The 
well was shot with 100 quarts of nitro-glycerin. As soon as pumping 
began, however, it was found that the casing was leaking, and after the 
first 75-80 barrels, the production of oil fell off rapidly until the well 
made only about three or four barrels of oil per day with about 25 
barrels of water. After many attempts the water was finally shut off 
through the use of rubber packers, but the production was not materially 
increased. Finally the well was reshot with 20 quarts of nitro, but the 
casing was loosened, so that water was again troublesome. The well 
can hardly be said to have had a fair chance to develop its possibilities. 
The next well, No. 3. was drilled on the Jackson-Church property 
near the west end of Bristol Street Bridge on the west side of Niagara 
Street and about 600 feet west of south from the Garey-Casamer well. 
The .Marshall, Berea, and the Traverse were approximately at the same 
depth as in the latter well, but there was no porous sandy limestone or 
(»il “sand” in the top of the Traverse. The “Saginaw Sand.” as the oil 
horizon in the Garey-Casamer well had been called, appeared to have 
pinched out, and there was not the slightest show of oil or gas at this 
horizon. 
The well was drilled down to the Dundee which was found at about 
2900 feet. At 2935 feet there was a show of oil which did not show much 
increase until at 2945 feet where the greatest showing was made up to 
2955 feet. The drilling was stopped at 3080 feet where some brine was 
struck. This was plugged off and the well shot with 120 quarts of nitro- 
glycerine. The first pumping is said to have yielded some 50 barrels of 
very good oil and then the production rapidly fell off to about 2 to 3 
barrels per day. 
A fourth well, about 1200 feet south of east from the Garey-Casamer. 
was sunk to the Dundee just at the east end of Bristol Street Bridge on 
the Cresswell property. The formations in all three of these wells in 
Saginaw were at approximately the same height. Tn flic Cresswell well, 
a showing of oil was struck in the “Saginaw Sand,” another about 100 
feet lower in the Traverse, and a third toward the base of the forma- 
tion. The oils in the second and third horizons were dark and heavy, 
and of much lower grade. None of these showings were deemed to be 
worth testing and the well was deepened to 3060 feet, the Dundee being 
struck at 2886 feet and a showing of oil found down to 2942 feet. The 
oil was high grade, being similar to that foound in the Jackson-Church 
well. 
Although the well has been drilled in for some lime. Tt has not been
