New GLascow CONGLOMERATE. 
Another of the debatable questions in Nova Scotian geological 
classification is that of the age of the New Glasgow Conglomerate. 
This formation is thus described by Sir William Logan: 
“At the bridge of New Glasgow is exposed a series of con- 
glomerates, which, in general colour, are between a brick-red 
and chocolate or Indian-red, and whose inclosed masses, varying 
from the smallest pebbles to boulders of two feet in diameter, 
are, for the most part, unmistakably derived from the red and 
greenish-gray sandstones, red shales and impure nodular lime- 
stones of the Millstone Grit, some of them containing the same 
vegetable organic remains. With these pebbles and boulders 
are associated a few from the rocks still lower down. The whole 
are inclosed in a matrix of the same mineral character, constitut- 
ing an argillo-arenaceous cement, which is also calcareous, and 
in the interstices of the boulders and pebbles is often observed a 
network of white calespar aiding to keep them together. There: 
are interstratified in the rock, bands, from afew inches to several 
feet in thickness, of fine red sandstone and red shale, which 
serve to give assurance of the dip, and these occur at such dis- 
tances apart as to render the conglomerate beds thick and
