GEOLOGY OF THE WHITE MOUNTAIN DISTRICT. 121 



half miles north of the mouth of Mt. Washington river the dip is S. 

 67"" \V. 



Passing from the summit hotels to the Lakes of the Clouds, one walks 

 over immense piles of angular fragments separated from the ledges by 

 intense refrigeration. The north-westerly dips near the point of depart- 

 ure have been mentioned. On a hummock north of the lakes the dip is 

 5° S. To the south of the lakes the rock is a slaty micaceous quartzite. 

 Beyond it is schistose again, dipping 75° westerly. The westerly dip of 

 the whole mass of Mt. Monroe is distinctly observable from Mt. Wash- 

 ington. The Crawford bridle-path passes around the east side of Monroe ; 

 and the schists grow gradually more feldspathic and granitic, so much so 

 that I called them all granite on my first trip over this road in 1858. 

 There are great veins of feldspar associated with them. On the east side 

 of Mt. Franklin there is a slide. Coarsely grained gneisses and mica 

 schists make up the summit of this mountain, dipping 10° west. 



A trip down the west side of Mt. Franklin, July 16, 1870, will always 

 be remembered by the party of young men who went v/ith me at that 

 time. We had walked from the "Twin River farm" to the summit of Mt. 

 Washington, and thence past the Lakes of the Clouds to Mt. Franklin, 

 and were exceedingly wearied. The side of the mountain appeared 

 smooth, and we anticipated a pleasant trip back again to our camp. 

 But the beautiful greensward turned itself into an inextricable labyrinth 

 of the short, stiff growth of subalpine evergreens for an interminable 

 distance, and the camp was not reached till quite late in the evening. 

 The last part of the way was through chopped trees which had not been 

 cleared off, and in the pitchy darkness proving to be a more serious 

 obstacle than the scrubby growth of the subalpine region. On reaching 

 the brook between Mts. Pleasant and Franklin the rock was found to 

 be quite ferruginous, but the same granitic gneiss with that on the sum- 

 mit of Franklin. It contains veins of coarse granite, showing a few 

 crystals of feldspar three inches long. This is followed by a width of 

 half to three fourths of a mile of clear, beautiful granite, showing nearly 

 horizontal jointed seams running through it, though their position is not 

 uniform. This is followed by a porphyritic variety of granite. 



In the gap between Mts. Franklin and Pleasant the usual schists of 

 this range dip N. 88° W. Mt. Pleasant is always known in scenic views
