HISTORY OF CURRIES MOUNTAIN. 
193 
Time of Eruption. — From the facts above stated it is easy 
to determine the time of overflow of the Curries Mountain 
lavas. Resting upon the red sediments of the Lower Carboni- 
ferous system they could not have reached the surface until 
near the close of the Lower Carboniferous period, or altogether 
subsequently; while, covered as they are by the lowest beds of 
the Coal-period, they must have antedated the latter. The time 
of eruption was between the two. 
Contemporaneous New Brunswick Volcanoes. — New 
Brunswick has been the seat of volcanic activity at many periods 
during its history both before and since that of which Curries 
Mountain is a monument. Volcanic products are a very marked 
feature of the so-called Huronian age, and in parts of St. John 
and Kings counties, as about Loch Lomoind, Kingston and the 
Nerepis region, cover large areas. They recur again in the 
Silurian, represented by many of the finer hills about the Bay 
des Chaleurs, Passamaquoddy Bay and the eminences, such as 
Mount Tenerifife, Mount Wightman, Sagaook Mountain, etc., at 
the sources of the Tobique and Nepisiquit; and in comparatively 
recent times there were the outflows now so conspicuously repre- 
sented fn the Bay of Fundy trough by Grand Manan and the 
North Mountains of Nova Scotia; but the Lower Carboniferous 
period is also remarkable for the extent to which volcanic 
operations were then carried on. One evidence of this is not 
very far removed from the locality which forms the subject of 
this paper. Upon what is known as the Royal Road, which 
runs in the rear or to the east of Curries Mountain at a distance 
of about five or six miles, is a conspicuous bluff known as 
McLeod’s Hill. Like the bluff at the ravine described above, 
and like most of the beds of volcanic origin of the Lower 
Carboniferous system, it presents upon one side a bold front, 
perpendicular towards the top but covered below with broken 
fragments, while in the opposite direction it slopes off more 
gradually and is mostly covered by superficial deposits. This
