for this failure to utilize so 
bountiful a supply of free 
power is that this particular 
locality has failed, geiieral- 
1}’, to meet the expectations 
of its first settlers. The 
town of Yellow Springs was 
laid out for a city of io,ooo 
inhabitants. It now has 
1,300. 
In the softer strata just 
under the overhanging cap 
rock, are some shaly seams. 
These act as water bearers, 
and as a result the gorge is 
well supplied with springs, 
some of considerable 
strength. The}' always ap-

It is interesting to note 
in this connection that this 
same stratum furnishes the 
remarkable iron spring 
which has given the town 
of Yellow Springs its name. 
The hard cap-rock (Ce- 
darville) when burned 
makes excellent lime : and 
yet, in over two miles of 
exposure we found the re- 
mains of but two limekilns. 
Not the least among the 
interesting things connect- 
ed with a stud}- of this 
gorge is the existence of an 
old abandoned channel. In 
1876, Prof. Claypole, then 
a professor in Antioch Col- 
lege, worked out this chan- 
nel very completely. The 
record of his work, unfor- 
tunately, is lost. All we 
know of his investigations 
is, that he dug into the 
channel to the depth of 
about 20 feet before reach- 
ing rock. At this depth the drill brought up a black, mucky soil
