Bahamas. The granite extends likewise along the 

 coast of New Hampshire and Maine, where it is 

 mixed with some sandstone, and likewise with lime- 

 stone, with which Boston is supplied from Maine. It 

 composes the numerous shoals on the coast of Nova Sco- 

 tia, and the nucleus of the mountains, called Notre 

 Dame and Magdalen, on the right of the mouth of the 

 St. Lawrence. The banks of this river are in ge- 

 neral schistus, but this does not prevent the granite 

 from showing itself frequently in detached masses, 

 and in shoals fixed in the bed of the river. It is 

 found again thi'oughout the environs of Quebec ; in 

 the mass of rock, that supports its citadel ; in the 

 tolerably lofty mountains north-west of the city ; ' 

 and lastly under the falls of Montmorenci, a small 

 river, which comes from the north, and precipi- 

 tates itself into the St. Lawrence down a precipice 

 of a hundred and eighty feet. The immediate bed 

 of this cascade is a horizontal calcareous shelf, of a 

 black grey colour, and of the kind termed primitive 

 or crystallized: but it is supported by strata of 

 brown-grey granite, of a very close grain, and near- 

 ly perpendicular to the horizon. Wherever these 

 strata show themselves along the St. Lawrence, 

 they are more or less inclined to the horizon, neve, 

 parallel with it. A granite of a red, black, and gre* 

 colour abounds on the right bank of the riyer, oppo* 

 site Quebec, resembling that of the State-house at 

 Boston, which was drawn from the neighbourhood 

 of the city ; "both being similar to the block that was 

 bi'ought from lake Ladoga to Petersburgh, to serv^ 

 as a pedestal for the statue of Peter L The isle i*
