80 feet deep, and falls in the middle of the town over a ledge of that 

 depth, composed of beds of quartzose limestone and calcareous sand- 

 stone containing shells, and abounding in hollows lined with stalag- 

 mitic incrustations.

 and the river Ristigouche in New Brunswick." by Mr. Henwood. 



Granite constitutes the lowest rock m the neighbourhood of Ba- 

 thurst (47°40' N. lat., 65° 42' W. long.), appearing about a mile from 

 the town on the banks of the Nepisiguit, and extending up its course 

 for three miles ; it is often traversed by granite veins of a finer and 

 more quartzose nature, particularly at the Pabineau falls. For the 

 whole of the above distance it is surmounted by the sandstones and 

 conglomerates of the coal-measures, the bedding of which conforms 

 almost perfectly to the surface of the granite. Near Long Meadow, a 

 greenish slate-rock, very much contorted in the cleavage planes, is in 

 contact with the granite and overlaid by a coarse quartzose conglo- 

 merate with apjjarently a ferruginous basis, and belonging to the 

 coal-measures. The greenish slate extends to the grand falls, con- 

 taining numerous quartz veins, and occasionally, as at the chain of 

 rocks, irregular masses of greenstone. 



Granite also runs for some miles up the courses of the Little and 

 Middle rivers, and near MoUoys, on the latter, it is overlaid by a 

 thick-bedded greenish slate, which is traversed near the junction of 

 the two rocks by numerous granite veins. In the bed of the Little 

 river, about eight miles from Bathurst, a fine glossy clay-slate ap- 

 pears. A fine deep blue clay- slate forms both banks of the Tattigouche 

 from the sea to Clarke's Camp, a distance of twenty-two miles, and is 

 overlaid near Blackstock's Mills by the quartzose conglomerate of 

 the coal-measures ; while at the Tattigouche falls a reddish brown 

 rock contains numerous small vermicular and nodular masses of 

 oxide of manganese. At this spot Mr. Henwood found a portion of 

 an encrinite, the only organic body seen by him. 



The coarse sandstones and quartzose conglomerates of the coal- 

 measures extend, Mr. Henwood believes, over the greater portion of 

 New Brunswick, being continuous, so far as he could discover, from 

 Fredericton (45*" 55' N. lat., 66° 45' W. long.) on the St. John's 

 river, to Boice's town, Newcastle and Chatham (about 47° N. lat., 

 65° 30' W. long.), on the Miramichi river, and thence to Bathurst, to 

 the northward of which they apparently terminate. In the last-men- 

 tioned locality so great abundance of vegetable remains have been 

 found, charged with vitreous and the blue and green carbonates of 

 copper, that mining operations have been conducted for the purjjose 

 of procuring the metallic minerals ; but the quantities obtained have 

 not repaid the expense, though the ores have been found over a con- 

 siderable tract. The bed containing the copper lies between two strata 

 of a coarse quartzose conglomerate, and appears to be a soft bluish 

 shale, enclosing in some places abundance of ferns and other plants. 

 Wherever there are any traces of woody fibre, the copper appears to 

 have been attracted to them ; but the largest quantity of ore has been 

 obtained in small nodular concretions, the centre of which is some-
