 empty space. . . . This curiosity occurs in a wild 

 part of the river's course, and in a solitude of moun-

 and the water-worn pillars upon either side display 

 ' pot-holes' and other evidences of erosion, and in the 

 bed of the current lie fragments of similar attrite rocks 

 which seem to indicate that at some period a series of 

 arches spanned the entire space from mountain to 

 mountain." ^

 found on the eastern slopes of Hoosac Mountain, above 

 the eastern portal of the Tunnel, formed ages before 

 the Hoosac Lake rippled in the * * hollow vale ' ' at 

 North Adams. The Natural Bridge of the Mayunsook 

 Valley is one of the greatest natural formations in

 widening as the loosened soil slipped off the bedrock
