beautiful precipice of siliceous breccia passing into graywacke, 
presents itself to the traveller. It consists of angular fragments 
of quartz and felspar, rarely containing a few spangles of mica 
united without any apparent cement. The felspar, being of a 
flesh-red color, and forming a principal ingredient in the rock, 
gives it an appearance ata distance resembling red sandstone. 
The precipice is about sixty feet high, and rises from a base of 
the same rock making the bed of the stream, which has excava- 
ted numerous deep holes into the bottom, forming beautiful reser- 
voirs of limpid water. The direction of the strata is N. E. and 
S. W. and the dip 10° to the northwest, forming a declivity down 
which the water rushes, and, falling from the broken strata, pro- 
duces an agreeable effect. This place, adorned with overshad- 
owing trees, is a favorite resort of the visitors of the Montague 
House, in its immediate vicinity. 
We shall now advert to the sandstone of Cumberland, and 
describe the quarries of grindstones and the coal dsitrict of this 
region. ‘The sandstone, where it emerges from beneath the trap 
at Cape D’Or, and where it comes in contact with it at Cape 
Chignecto, exhibits the red color noticed at other places in the 
vicinity of this rock, is more compact, and is destitute of organic 
remains. Leaving its Plutonic neighbour further up Cumber- 
land Bay, it assumes a grey color. It alternates with, and passes 
into, a coarse conglomerate. At Apple River and the South Joggin 
it is quarried for grindstones and as a building material. This 
sandstone passes into the neighbouring Province of New Bruns- 
wick, forming the extensive grindstone quarries of Meringuin and 
Grindstone Islands, and is undoubtedly connected with the for- 
mation of this rock that includes the coal measures recently dis- 
covered on the Grand Lake in the interior parts of that province,
