and more than 1200 feet at Midland. Southeast of Saginaw the Marshall 
and the Berea also appeared to be much higher. To the north of Sag- 
inaw. there is a pronounced upward fold in the Coal Measures as ob- 
served in the Ralston well (See. 4. T. 13 X., R. 4 E.). The Marshall and 
the < Yddwater also appear to be somewhat higher in the Page Oil and 
Oas Co. well (Sec. 20. T. 14 X., R. 4 E.) than they are farther east 
along Saginaw river. At Kawkawlin. the brine horizons occur between 
700-800 feet or considerably shallower than in Bay City. From the 
foregoing evidence, it seemed fairly certain that a pronounced anticlinal 
fold existed in the rock strata down to the Marshall at least, and pre- 
sumably much deeper. Apparently this fold should run slightly west 
of north through Saginaw near Bristol St. Bridge to a point two or 
three miles west of Kawkawlin. To the southeast of Saginaw at Black- 
mar. the Marshall and Berea were apparently struck at 360 and 1545 feet 
and at Flint, 170 and 1200 feet respectively. As this is considerably 
higher than at points to the east or west of these places, the anticline 
appears to turn more to the southeast toward Blackmar and Flint, but 
the evidence is not definite or conclusive, as the records of the drillings 
at these places are very imperfect. As the Marshall appeared to be 
only about 360 feet deep at Blackmar, 610 feet at Saginaw and about 
700 feet at Kawkawlin, the structure apparently pitched gently to the 
north. On the whole, the evidence was fairly conclusive that an an- 
ticlinal structure existed, but its exact position and direction were not 
so clearly indicated. 
The first well was put down by the Saginaw Development Company 
near the SE. Cor. of the XW. V 4 of XW. % of Sec. 27, T. 13 X., R. 
5 E., Buena Vista township, Saginaw county, although from the evi- 
dence then at hand, this location appeared to be considerably to the 
east of the supposed anticlinal. In this well, known as the Mundy- 
Fi field, the Marshall was found at 780 feet or 40 feet higher than in 
the South Bay City well (Sec. 5, T. 13 X.. R. 5 E.) but fully 170 feet 
lower than the supposed depth to the Napoleon near the Old Wylie well 
on Niagara St. about 800 feet north of Bristol St. Bridge. The Berea 
was struck at 2070 feet or 30 feet higher than in ihe South Bay City 
well. All of ihe underlying formations were correspondingly higher 
than the respective ones in the Bay City wells and much lower than at 
Saginaw, as was afterwards shown by later drillings. From the first 
it was obvious that the well was located well down the east limb of the 
anticline. The Berea yielded some brine and a little gas, but no show 
of oil. At the depth of 2246 feet the drilling was* abandoned, but after- 
wards it was deepened to the Traverse oil horizon, which was struck 
at. 2520 feet or 00 feet higher than at Bay City and 200 feet lower than 
at Saginaw. There was about 20 feet of the “sand” but no oil or gas. 
The well is now being drilled to the Dundee but the chances for finding- 
oil and gas do not seem at all favorable. The well is located too far 
from the anticline. 
Another well was started near the site of the old Wylie Bros, well 
on what is known as the Garey-Casamer lease. Here the Upper Marshall 
or Xapoleon was found at 510 feet or 170 feet higher than in the Mundy- 
Fifield well and 210 feet higher than in the South Bay City. The Berea 
was encountered at 1835 feet or 235 feet higher than in the Mundy- 
Fifield and 265 feet higher than at Bay City. These drillings not only
