I/O STKATIGRAPHICAL GEOLOGY. 



scribed in the first and second cuttings. Tlic dips cannot be discerned 

 so easily as in the cuttings, on account of weathering. In the original 

 Notch there is only just room enough for the small Saco river and the 

 carriage-road. The most prominent joints have the courses N. 58° E. 

 and N. 32^ W., being vertical, and dipping 70° easterly. Another runs 

 north-easterly. By their intersection the rock is cut into quadran- 

 gular blocks of large size, sometimes isolated by the denudation of the 

 surrounding mass. Such is the " Pulpit." On the east side of the road 

 one sees also small valleys, made by the enlargement of the jointed planes 

 through erosion of softer seams, sometimes veins or dykes. Other irreg- 

 ularities are fancied by tourists to be the profiles of the " Young Man," 

 " Old Maid," " Baby," etc., — which resemblances are not striking. Over 

 against the lower part of the second railroad cut is a great mass of the 

 schist cut into blocks by N. E. and N. 36° W. joints. There is also a 

 south-west flume-like excavation, six or eight feet wide, separating another 

 smaller mass of schists from the first, through which the Saco may run 

 at times, there being another course nearer the road. The northern side 

 is fifty and the southern thirty feet above the stream. Following it 

 around nearly to the south end of the railroad cut, one will find a cave in 

 the hard rock, produced by the enlargement of one of the jointed seams. 

 Very soon the road overlooks the Dismal pool, an expansion of the Saco, 

 rendered larger of late by the fragments of rock thrown down by blast- 

 ing. This is 225 feet lower than the track at the James cut, and not 

 quite so far beneath the road. A little farther south, where the road 

 makes its greatest amount of westing, the hard schists may dip north- 

 easterly. This curve in the road is occasioned by the occurrence of a 

 spur of hard rock on the east. At some distance below we pass in suc- 

 cession the Flume and Silver cascades. 



Next, our attention may be directed to the distribution of the Breccia 

 granite. It was said to dip somewhat east of north along the railroad. 

 Coming down to the mouth of Dismal pool, the high cliff seen to the 

 east, connected with the most western angle of the road, is composed of 

 the usual hard schists, traversed by numerous veins of coarse granite. 

 The Breccia granite dips under it in the direction N. 58° E., only the 

 upper part of it showing. From thence it may be traced south-easterly to 

 the Silver cascade, crossing the road about by the Flume cascade, or a
