granite are different from any rocks found in place in the immediate 

 vicinity. The nearest granite ledge is one mile north of it, but is of a 

 different kind. The original bed must be some distance to the north-

Conway Boulders. Prof. E. J. Houston describes a large boulder, near 

 the house of E. S. Stokes, North Conway, in much detail in the journal 

 of the Franklin Institute, Volume LXH, 1871. He calls it the Pequaw- 

 ket boulder. It is of coarse granite, with a preponderance of feldspar, 

 considerable quartz, and very little mica. The general form is that of a 

 parallelepiped, one of whose longer sides is partly buried. The length 

 is 52 feet 6 inches; greatest breadth, 21 feet; greatest height, 33 feet 2 

 inches; and it is estimated to weigh 2,300 tons. Several large fragments 

 surround the mass, seemingly once connected with it. One is 31 feet 3 

 inches long, 15 broad, and 21 high. On the south-east side is another 

 piece 31 feet 7 inches long, 15 feet 3 inches broad, and 11 feet 7 inches 

 high. Several spruces and beeches conceal the boulder from the road.
