‘ am indebted for a description of that locality, thinks it 
possible, though not probable, that the drift has covered the 
rock there to a depth of one hundred feet; but yet another 
hundred of feet is needed to complete the dam. So we are 
not permitted to think that the successive water stages have 
been caused by the gradual cutting through of a high barrier. 
There seems to me to remain but one hypothesis, and that the 
true one; that the warping of the rim of the lake basin 
has taken place; that there has been local subsidence, or 
upheaval, or both, so that Fort Wayne is now relatively 
much higher than formerly; and that it has been by the 
contortion of the great reservoir, that the point of its outflow 
has been shifted from point to point, and its capacity has 
been varied.
