240 GLACIAL GEAVELS OF MAINE. 



the southeast shore of Swan Island, in the Kennebec River; (3) in the vil- 

 lage of Sabatisville; (4) near the head of Little Kennebec Bay, a few miles 

 south of Machias Village; (5) at Winslows Mills, in Waldoboro. It might 

 be expected that the tongue of ice that filled the basin of Sebago Lake 

 would in like manner confront the sea, and, in consequence of the abundant 

 flow of ice from the north, would retreat with relative slowness, a condition 

 favorable to the formation of a terminal moraine. 



NAPLES-STANDISH SERIES. 



A terrace-like ridge or level plain of sand skirts the western shore of 

 Long Pond for three-fourths of a mile north of Naples Village. At this 

 point it rises somewhat more than 20 feet above the pond, and there is no 

 similar deposit on the east side of the pond, nor around the pond. The 

 terrace at Naples Village is at least 10 feet deep. Is it an old beach, formed 

 at a time when the pond stood 20 or more feet above its present level? 



1. If a terrace 10 feet deep could form as a beach on the west side of 

 the pond and in a sheltered situation, then similar beaches ought to be 

 found in all the sheltered bays of the lake, especially on the east side. 

 There are no such beaches deep enough to be traceable. 



2. The erosion cliffs along the shores of the pond at its present level 

 are too small to account for a terrace of sand near one-eighth of a mile 

 wide and 10 feet deep. If the Naples terrace is a beach, then a corre- 

 sponding erosion cliff or other sign of the erosion ought to be found around 

 the lake. There is proof that the lake must have formerly stood at a higher 

 level than at present, but it has left no cliffs, nor any places denuded of till, 

 nor anj" recognizable beaches. 



3. No stream, except mere brooks about a mile long can ever have 

 flowed into Long Pond at Naples Village. The sand terrace can not, there- 

 fore, be a delta brought by streams into the lake at a time when it stood at 

 a higher level than at present. 



It thus appears that the sand terrace at Naples is neither a beach nor a 

 lake delta, and the onl}- way to account for it is to assume that it is an osar- 

 plain. The plain continues southward along the west shore of Brandy 

 Pond (Bay of Naples), becoming coarser toward the south; and at the out- 

 let of this pond it has become a two-sided ridge with arched stratification. 

 .At this point there are several outlying ridges, somewhat reticulated, one
