180 G 5 . REPORT OF PROGRESS. I. C. WHITE. 



At Tanner's Falls, its base comes in the hills at 1300' A. 

 T. At 150' lower, we see a very massive, greenish-gray stra- 

 tum, over which Dyeberry makes a plunge of about 25' at 

 the Falls, thus affording very fine water-power for the im- 

 mense tannery located there. 



Glass sand. — Two miles northwest from Bethany, the old 

 county seat, there are two small lakelets which are gen- 

 erally known by the names of Glass Factory Ponds, since 

 in former times a glass manufactory obtained its sand around 

 their shores. The origin of these beds of loose sand, fit for 

 glass making purposes has been quite a mystery to many, 

 but the matter is easily solved when one observes closely 

 the character of the surroundings ; for, extending all around 

 the lower pond is a low cliff of grayish- white sandstone, 

 partially submerged. The gradual decay of this stratum 

 through swash of the waves and other atmospheric influences 

 has furnished the sand grains ; the wear and tear of the 

 grinding has pulverized the finer material, and at the same 

 time thrown up the sands in heaps where we now find them. 

 It is possible that the grinding action of the northern ice 

 filling these ponds may have contributed something to- 

 ward the pulverization of the sandstone, but that its origin 

 came about from the action of some forces on this local rock 

 cannot be doubted. The stratum which skirts the pond at 

 an elevation of 1475' above tide, is the Cherry Ridge con- 

 glomerate or at least one of the sandy deposits of that group. 



These ponds are supplied by springs and the city of Hones- 

 dale now receives its water from them through the new works 

 that have recently been erected.
