SCENOGRAPHICAL GEOLOGY. 617 



Adams. It is at the same level with the highest supposed foreign peb- 

 bles on Washington, and therefore may have never been covered by 

 moving ice. 



Adams has a double summit, as appears in Fig. 81. We may, for con- 

 venience, call the lesser one, which is farther to the south, Mt Quincy 

 Adams. It rises out of a very level space, perhaps a part of our plateau 

 described above. The view from Adams is very much the same as from 

 Washington, save that we see the highest of the White Mountains, which 

 cuts off the south-western view, as would appear from Fig. 71. The 

 country to the north is also more exactly defined. In a visit to Adams, 

 made about the first of May, at the time of our occupation of the sum- 

 mit of Mt. Washington for meteorological purposes, I found the path 

 more comfortable than in summer, because snow filled up many of the 

 lacunae between the rough blocks. On a subsequent occasion, tourists 

 visiting Adams could plainly hear shouting upon Mt. Washington, a dis- 

 tance of four miles in an air line. 



The rest of the route to Washington is less exciting than up King's 

 ravine, but oftentimes adventurous and everywhere delightful views are 

 afforded. Upon Mt. Jefferson is the curious castellated ridge, shown on 

 page 28, and also the Sentinel (Fig. 76). The lowest part of the notch 

 between Adams and Jefferson has a very narrow summit, the ground 

 sloping steeply on both sides from a mere line. The uniform gray tint 

 of the rocks on the north flank of Jefferson is relieved by many pure 

 white blocks of quartz. The hummocks of Mt. Clay show more reg- 

 ularity of stratification than any of the other peaks, while the slope 

 towards the gulf is precipitous and impassable. 



THE ASCENT OF MT. WASHINGTON. 



The three thoroughfares ascending Mt. Washington, most commonly 

 used by tourists, are the Crawford bridle-path, the carriage-road from 

 the Glen, and the railroad from Ammonoosuc station. The latter will 

 very soon connect with the Boston, Concord & Montreal Railroad, so 

 that one can ride from Boston to the summit, with only one change of 

 cars, in ten hours' time. The Davis bridle-path from the Mt. Crawford 

 house, the foot-path to Mt. Pleasant from the Giant's grave, the Lan- 

 caster way, and the older roads from the Glen and Fabyan's, are now
