The following is the log of the Welle-Boettler well as given to the 
U. S. Geological Survey by the driller and the oil and gas shale at 600 
to 620 feet, was regarded as of Devonian age.

On the Drummond lot at 3904 Forest Park boulevard a test well 
was drilled about 700 feet deep. This was 250 feet southeast of the 
Welle-Boettler wells; another test well was drilled on the east side of 
Vandeventer avenue, about 400 feet farther southeast, but ‘both were 
barren. . 
At the Tamm glue factory, Manchester and Wabash R. R., two tests 
were drilled, one of which yielded a little gas at 505 feet and more 
at 760 feet and which showed a pressure of 42 pounds when shut in. 
The amount was not encouraging, however, and the well is now full of 
salt water. 
From samples of the drillings placed at my disposal by Mr. Tamm, 
the following tentative log of his gas or No. 9° well is herewith sub- 
mitted.
