HISTORY OF CURRIES MOUNTAIN.

ash, which in places assumes the character of a coarse 
amygdaloid or toad-stone. No bedding is discernible in these 
rocks, but they may be seen to rest horizontally upon non- 
volcanic stratified rocks to be presently noticed, showing that 
they are either of the nature of flows or of showers of ashes. 
They may be well studied on either side of a ravine traversing 
the hillside about a mile and a half above Curries Mountain, 
where they form a conspicuous and vertical bluff, half-buried by 
a talus of detached fragments, and commanding a view probably 
unexcelled in beauty in the whole valley of the St. John. 
Sedimentary Rocks. — The rocks of this character found 
associated with the volcanics consist of conglomerates, sand- 
stones and shales, of which those below the volcanics are 
noticeable for their intensely red colour and calcareous nature, 
while those above are as uniformly grey and non-calcareous. 
The former are identical with those which in various other parts 
of the Province occupy a similar position and are referable to 
the Lower Carboniferous system, while the latter represent the 
Millstone Grit formation or Lower Division of the Coal 
Measures. The latter are remarkable as mainly made up of 
well-rounded white quartz pebbles. The red rocks may to some 
extent be seen along the Back Road where this makes its ascent 
to the hills behind Curries Mountain, but better in the ravine 
referred to above or along the steep hillsides leading to Rockland. 
From the height of the hills, the horizontal attitude of the beds, 
and the position of the exposures, it may be inferred that they 
have a thickness of at least five hundred feet. The grey beds 
are not seen in the immediate vicinity of the mountain, but come 
into view on either side, in one direction becoming continuous 
with the great Carboniferous tract of southern New Brunswick, 
in the other helping to mark the northern escarpment of that 
formation to and up the valley of the Keswick River. They are 
noticeable, in addition to their coarseness and silicious character, 
for the extent to which they have been planed and even polished 
by glacial action. Poorly preserved stems of plants are occasion- 
ally found in the red as well as in the grey beds.
