Mineralogy and Geology of a part of Nova Scotia, 151 
cause we are not informed, No rock salt has ever been 
found in ele vicinity of these springs, nor has the e rock any 
perceptible salt taste. We must therefore refer the origin 
and the occurrence of these salt springs to such unexplained 
phenomena as are ass Rene to those in the western part of 
the state of New-York, so abiy di =wticas by Prof. Eaton in 
his “ Geological and ogg ee Survey of the District ad- 
joining the Erie Cana See Part I. p. 109. sqq. The ex- 
istence of salt spri a in this eeaains indicates it to be 
identical with the saliferous rock of Phillips and Conybeare, 
and ‘o the extensive deposit described by Prof. Ea- 
in the western part of the state of New-York, 
in his aeealliont survey of the Erie Canal, and in the Amer. 
Journ. of Science, vol. xiv. No. 1, p. 148, as existing on the 
banks of the Conndiiaent: and as supporting the Palisades 
on the Hudson river. 
Pursuing this formation eastwardly in the direction of its 
strata, we meet with occasional beds of coal, not of any 
poten worth, and offering no remarkable geological bo 
culiarities. On the north bank of the West river, where t 
Kempt bridge crosses this ry er ituminous oe’ 
cliff of sandstone, a section of eittebea is as by the bed of 
the river. At this place, which we mention se a of 
its vicinity to the road from Truro to Pictou, renderi ring it ac- 
cessible to travellers, occur many of ee — of culmiferous 
plants before noticed at Cumberland 
Carriboo river, in the township of New Philadelphia, seven 
miles north of the flourishing town of Pictou, presents a field 
of great interest both to the mineralogist and the miner. On 
of this stream, two miles from where it empties 
aicabe Gulf of St. Lawrence, occurs a bed of copper ore, 
included between the strata of sandstone passing into coarse 
conglomerate, It is associated with lignites of enormous 
size, which generally lie over the copper ore. ‘The conglom- 
erate consists of smooth rounded masses of quartz of various 
rey eh slate, clay-slate, and felspar, varying in size 
from tha) a filbert to three or four inches in diameter; 
by the naked eye. These rocks rise from te river to ore 
height of fifteen or twenty feet above its level, and
