WOOD COUNTY. 375 
Owing to the abundance of the Drift deposits and the monotony of topo- 
graphical features in Wood county, there is no opportunity afforded for 
ascertaining the stratigraphical relations of these three phases of the 
Waterlime; yet it is certain that phases Nos. 1 and 2 disappear from the 
formation toward the south, and phase No. 3 is more largely developed, 
and seems to acquire more bituminous matter, becoming a thin-bedded 
but tough slate. Its characteristic outcrop in Wyandot county has re- 
ceived the name of the Tymochtee slate. Phase No. 1 is believed to occur 
at different but not constant horizons in the formation, but seems to pre- 
vail especially in the upper portions. Phase No. 2 has been seen in 
Wood county only in such positions as would place it in the lowest por- 
tion of the Waterlime.* 
The Maumee River lies almost constantly on the Waterlime from the 
west line of the county to Perrysburg. It traverses, however, in that 
distance, the Oriskany sandstone three times. Throughout this distance 
the Waterlime shows the lithological characters of phases No. 1 and No. 3, 
those of the latter being far more frequent than the former. No. 1 was 
noticed especially at a point about half a mile above Miltonville. At a 
point a mile below Miltonville the following section was taken:

often lined with calcite crystals, and also sometimes

The bituminous appearance of the rock for a mile both above and 
below Miltonville is so conspicuous, in the form of gummy asphaltum 
contained in the numerous cavities, and not infrequently staining and 
making fetid the rock itself, as to induce considerable expense in drill- 
ing for petroleum. One well, which descended about eight hundred feet,

Waterlime contains similar beds; also quarry No. 3, at Tiffin, in Seneca county.
