I96 PHYSICAL GEOGRAPHY. 



Albany Mountains. Swift river divides the Albany mountains into two 

 parts, rising on the long easterly slopes of the Carrigain-Osceola range and 

 Green's cliff. Those just described form the southern rim of this basin. 

 Those upon the north side are the Mote mountains, adjacent to Conway, 

 and mostly unnamed peaks along the south bank of the Saco in Bartlett, 

 joining on to Tremont in a wild tract of forest. The Mote mountains 

 have been burnt over, so that they appear unusually barren when seen 

 from a distance. They are the newest of the White Mountains, while 

 the foundations of the Passaconnaway range are the oldest. With a 

 different arrangement of description, the Albany basin may be said to 

 have very gentle slopes upon the inside, but on the Saco valley range 

 and the Chocorua group the hills dip abruptly in opposite directions. 

 This basin may also be termed a projection eastwardly from the Carri- 

 gain range. 



8. Alts. Lafayette and Tzuin. This area is bounded on the north by 

 the Ammonoosuc, on the east by New Zealand river and the east branch 

 of the Pemigewasset, which curves so as to make it the south line, 

 also, on the west by the north branch of the Pemigewasset. It contains 

 two prominent ranges, first, the western one, from Haystack to the junc- 

 tion of the two branch streams ; and the other, from the Twin mountains 

 to the mouth of the Franconia branch. The Haystack, a conical peak, is 

 separated by a series of small gaps from Lafayette. The Lafayette 

 mountains are peculiar in form. The range is quite elevated, extremely 

 narrow, and consisting of seven summits. Lafayette, 5,290 feet, is the 

 second from the north. Then follow Mt. Lincoln of Fifield, 5,101 feet, 

 two nameless peaks, Mts. Liberty and Flume, each 4,500 feet, the latter 

 to the south-east of the usual course of the ridge. This elevated ridge 

 is composed of dark felsite. The peaks south of Mt. Flume are coarsely 

 granitic, being Big and Little Coolidge, Potash mountain, and others. 



The Twin mountain range occupies the middle line between the Saco 

 and Pemigewasset rivers. The two most prominent peaks are a mile 

 apart, eight miles south of the Twin Mountain house, and are 5,000 feet 

 high. Scarcely any mountains are more difficult to reach than these, on 

 account of the stunted growth near their tops. The ridge is broad, and 

 keeps at almost the same level for two or three miles south of the summit. 

 On the west of this range there is an isolated ridge of no great dimen-
