FALLS OF LANA. 353 



There is a short range of talcose schist, mostly, which is colored as quartz rock, 

 commencing near the Furnace, and passing a little east of north, near a small stream into 

 Chittenden, and terminates near Chittenden Cave, near Mckwacket Mountain. Near its 

 north end, its course is N. 10 E., and its inclination is 56 E. Its junction with the lime- 

 stone east of it is perfect the latter overlying the former. This range does not con- 

 nect at either end with the principal range. 



Two other long spurs of quartz rock terminate in Pittsford. The most eastern spur 

 terminates in the south part of the principal village in Pittsford, upon Furnace Brook. 

 One would think from an inspection of the map, that this spur must connect with the 

 north end of the subordinate range in Rutland. The rock upon this spur is an indefinite 

 kind of quartz rock, passing into conglomerate. Upon the east side of Sugar Hollow 

 River, in the north part of Pittsford, the strata of conglomerate run N. 10 E. West of 

 this range, in the limestone in the bed of the river, there is about fifty feet thickness 

 of slate and conglomerate not connected with the principal range. The most western 

 spur of all, terminates north of the Pittsford R. R. Station. It does not unite with the 

 principal range, certainly south of Lake Dunmore. The relations of these different 

 ranges of quartz rock and limestones to one another, in Pittsford, etc., need investigation. 

 We have delineated upon the map, the facts so far as they are known ; and a better idea 

 of the numbers and shapes of the different spurs and ranges can be obtained by a hasty 

 inspection of the map, than by many pages of particular description. 



From Pittsford, the quartz rock, in several ranges, pursues a direct course for 

 Forestdale in Brandon, on Section VII. 



Lake Dunmore is in the west part of the formation. East of the water, the quartz 

 rock rises abruptly into a mountain range. We are happy to be able to present a few 

 words respecting its occurrence about the falls of the Lana, written by Rev. Augustus 

 Wing, of Stockbridge, who visited the place at our request. The letter was addressed to 

 C. H. Hitchcock : 



"I went to the Falls of Lana, on the east side of Lake Dunmore, the day after leaving you. The brown 

 quartz dips about 80 W. at the foot of the hill. A few rods east the semi-vitreous quartz occurs in great 

 force, being in solid compact strata from ten to twenty feet thick, and standing nearly perpendicular. It is 

 tliis mass of unusually compact rock that forms the principal barrier to the brook, and thus makes the falls. 

 The stream is not as large as some others crossing the same range, in like manner, yet it was sufficient to 

 drive a saw mill, as the remains of one still witness. The reason why the river has not entirely cut through 

 the range, as it has at Bristol, East Middlebury, Brandon, and Kutland, is the occurrence of a greater amount 

 of the semi-vitreous or hyaline quartz. At Bristol, you will recollect, in the gorge there was none whatever. 

 At Brandon there are only two strata of it : one of them, two feet thick, was as true as a die across the 

 brook, half a mile above Blake's furnace ; the other is a short distance north. It was pointed out to me as 

 a " curiosity." At East Middlebury the hyaline quartz I know is thirty or forty feet thick, and the stream 

 has cut a deep passage through it under difficult circumstances : but that is of less account than the rock at 

 the Falls of Lana. 



"But I am forgetting the Falls. Suffice it to say, you ride a mile further than we did, walk another and 

 you are at the stream hearing the noise of many waters above you. With curiosity excited, you hasten up 

 the path, a steep shaded ascent for an eighth of a mile, and stand upon a precipice viewing the white 

 waters foaming in an irregular narrow channel beneath some sixty feet. Next you wind down on the edge 

 of the cliff to a circular basin at the foot of the falls. You go round under high projecting rocks, fearing 

 they will fall, but know they will not, till you come round and up to the top of the falls. You step out
