HISTORY OF C OH ASSET. 



Pond and those several deep holes west of the North 

 Schoohouse. 



Another lies along the middle of Levi Tower's estate, 

 and Green Street dips down into it between Sohier 

 Street and North Main Street. People who climb the 

 little steep in front of the Sohier estate on North Main 

 Street are put to that trouble just because a large fragment 

 of the glacier happened to stay unmelted at that hollow, 

 when the soil was being spread by the glacial stream. 



Prof. George F. Wright, in his investigations at the 

 Muir glacier, Alaska, caught one of these fragments of 

 ice in the very act of making a punch bowl. The dirt 

 which covered the little hill of ice kept sliding down to the 

 edge as the melting progressed, so that there was nothing 

 to be left in the middle when the ice should have 

 disappeared. 



Wherever one digs down into the gravel anywhere in 

 this region of North Main Street he can see how the 

 water laid it in strata, some coarse, some fine, according 

 as the successive seasons changed the rapidity and the 

 course of the stream. One feels a shock of conviction 

 upon seeing these sure signs of running water, added to 

 the fact that all the fine stuff, like the clay, for example, 

 has been carried off. The Edward E. Tower gravel bank 

 on North Main Street is possible only because that glacial 

 stream carried away thousands of tons of fine dirt, while 

 the gravel was being left. Much of it may be lying now 

 in the broad meadow where the Catholic Church stands, 

 and much has gone to sea. 



This gleaning out has made good roads an easier matter, 

 and has furnished excellent drainage for cesspools ; but it 

 leaves the North End plains a poorer kind of farming soil 

 than that which is upon the sidehills, the drumlins that 

 have kept their clay. 



There is another important sand plain in the town made 

 in a similar way, and furnishing another convenient site
