foreground of the photograph; this curve marks the level where 
it paused for a time in the relatively rapid cutting of its channel 
in the unconsolidated glacial drift. A diagrammatic profile of 
this bench is shown in fig. 4. 
Nearly a mile east of Claylick, at the point M, there is a much 
larger bench whose level coincides with that of the terrace in val- 
ley By and is five feet lower in elevation than the sag K. The ter- 
race can be traced around the valley, sloping gently from the sag 
to the bench. This bench was carved in the slope of the valley 
wall at this point, where there must have been a spur extending 
in a northwest direction into the valley. Almost in the center of

the bench a well has been sunk to a depth of sixty feet. It passes \^ 
through ten feet of sand and gravel before it reaches the underlying j : 
rock which outcrops on the hillslope adjoining the bench on the : 
east. At the western end of the bench there is a slight elevation 1 1 
of two to three feet, formed by an outcropping knoll of the same 
bed-rock. This gives the bench a profile as shown in fig. 4. 
It is evident that at the time the terraces were formed the drain- 
age from valley B flowed across this bench, producing its present 
shape. To do this the lateral stream from the glacier must have 
been held against the valley wall by the front of the ice. 
Two miles east of Claylick, just at the entrance to the Licking 
Narrows, there are two more abandoned channels which were
