of the arm there is a large and deep kettle-hole continuing the 
line toward the Beaver Pond depression. Further, the latter 
depression just southwest stretches out two long arms eastward, 
suggesting former junction. A dozen other kettle-holes lie to 
the south and southwest of the Pine Marsh depression ; and 
other arms extend toward them from the Beaver Pond area. 
Although the plain around has the normal height (as the map 
shows) the arms and kettle-holes look exceedingly (more so in 
the field than on the map) as if a former channel had existed 
and had become mostly obliterated by sand and gravel deposits. 
3. A former union of Pine Marsh channel with the Beaver 
Pond channel almost necessarily implies a continuation of the 
channel to the head of the bay; and such a continuation is 
plainly indicated by the ranges of arms and kettle-holes ex- 
tending from the southeastern portion of the latter channel 
toward and into the Hast Oreek channel (see map). he arms. 
leading from the depression are in fact kettle-holes partially 
coalescing with it; and the kettle-holes make two almost con-

The southern of the two lines is over 1,000 feet long. Again, 
farther south, near the south end of the Beaver Pond depres- 
Sion, still another line about 2,000 feet long, consisting of two 
Kettle-holes (one 500 feet in diameter with formerly a pond at 
bottom) and a long depression,+ make another connection with
