the region of lake Ontario. The arrangement of tributary streams to the 
west is also more normal to a westward than an eastward flowing stream, 
An inspection of the course of the Sauquoit, Oriskany, and Nine Mile 
creeks will support this suggestion, particularly if the hint given later as 
to the former course of the West Canada creek proves tenable. The upper 
Mohawk for several miles above Rome probably also took a more west- 
erly course. Decisive weight cannot be given to the arrangement of 
streams in this.case, however, since a normal dendritic arrangement is 
hardly to be expected if a subsequent Rome river diverted its tributaries 
from consequent courses. 
ROCK TOPOGRAPHY WEST OF LITTLE FALLS 
Information concerning wells between Little Falls and Oneida, as above 
indicated, demonstrates descent of the rock floor westward, and also 
seems to prove the existence of a rock basin between Utica and Little 
Falls. The records at hand are given below.* 
At Herkimer a.well was put down by the West Canada creek, perhaps 
a half mile from the main valley, disclosing the following succession :

At Mohawk, on the south edge of the valley, a well at the knitting 
mill, by the canal, shows this section—rock not being reached :

At Ilion we have the following from the well at the Remington Stand-

and the location on the south edge of the floodplain. The drift is 195 
feet in thickness, mainly of fine gravel. Two beds of quicksand, each

of Utica. The last has drilled extensively in central New York.
