located and another in the general direction of the present river 
gorge. Erosion then began, and evidently this proceeded more 
rapidly in the latter, and a constantly increasing volume of the 
stream was diverted to this lower level outlet. The flow of 
water through the other outlet constantly decreased, ceased 
entirely, and the depression became a cut-off or slough, which 
eventually was silted up and ee into a bog, and this now 
furnishes the fine, black soil for the plantations located there. 
h antime the river was constantly cutting its now 
single channel deeper, and eroding the side walls. Pot-holes 
were formed in the rock of the river bed, at successively lower 
and lower levels. Many were, doubtless, subsequently obliter- 
ated as the river cut its way down and eroded its banks; but the 
two here described were left where they may yet be seen, with the 
river flowing far below.
