No. 4. The highway leading north from Jones Corners inter- 
cepts a brook just before the first road-crossing. Commencing 
a few rods east of this highway an esker extends down the slope 
of the valley for about one-fourth of a mile. No development 
of the ridge was noted to the west of the highway. Since the

valley; the sag near the left is a marked kame area. The camera points a little 
north of a line normal to the axis of this glacially aggraded valley. 
direction of this esker is longitudinal to the valley, we would | 
anticipate a greater length. The grade of course favors pro- j 
nounced flow of the subglacial stream. Where the esker ridge i 
becomes discontinuous the valley moraine is well develo ed. 
This fact suggests the possible deformation of the esker ridge by 
the ice-front deposits. Certain drift accumulations, ridge-like | 
in form, have been mapped as possibly disconnected segments of |: 
the original esker. About halfway down this valley an abandoned ■ 
lime kiln stands on one such segment. About the surface of both
