position often made that these sides have been separated from each 

 other. The length of this gorge is from 30 to 40 rods. Above is a 

 £eep glen ; and below, the stream passes through a deep ravine. 

 Two water falls near the lower part of the gorge add much to the in- 

 terest of this spot. And although the geological chronometer here ex- 

 hibited, is to the reflecting mind, its greatest attractions ; yet the wild- 

 ness and ruggedness of the scenery draw not a few visitors. The 

 term " glen," usually applied to this spot, is certainly a misnomer. 

 For it is a gorge connecting a glen with a ravine. 



Cascade in Leverett. 



I have recently ascertained the existence of an interesting water 

 fall on the northeast side of Mount Toby, in Leverett. The con- 

 glomerate rock of that mountain has been subject to powerful abra- 

 sion in early times ; and being divisible into masses of great thick- 

 ness, by fissures nearly perpendicular to the horizon, the sides of the 

 mountain frequently present perpendicular walls of solid rock, and 

 sometimes a succession of precipices in the form of vast steps; 

 while the huge fragments that have fallen down, lie scattered along 

 the base. Such is the case at the spot above referred to ; where a 

 large brook, called " roaring brook," comes tumbling down by a few 

 successive leaps from the height of 200 or 300 feet. The waters 

 have worn deep chasms in the rocks, and the scenery around is of 

 the wildest and most romantic character. Every thing there — the 

 lofty forests — the overhanging precipices — and the accumulated rocky 

 masses below — remain unmodified by the hand of man, just as the 

 mighty agencies of nature have left them. 



Cascade, Natural Bridge, and Fissure, on Hudso?i's Brook 



The present falls on this rivulet, which runs through the north 

 part of Adams, are of far less interest than the deep chasm which its 

 waters have excavated in the white limestone. This limestone ter- 

 minates on the south in a high precipice, over which the stream once 

 fell. But it has worn a fissure from 30 to 60 feet deep, and 30 rods 

 long, in this limestone, and left two masses of rock connecting the 

 sides and forming natural bridges ; though the upper one is much 

 broken. The lower one is arched, and the stream at present runs 50 

 feet below it. The medium width of the stream is 1 5 feet.
