of jet black tourmaline are often found prevailing in clusters. 
Specimens of those in the museum collection are very strik- 
ing. There is a specimen in our Webster Collection, it is 
probable that it has come from the granite region of Paradise, 
Annapolis County, where white quartz with groups of black tour- 
maline is of frequent occurrence. The specimen is a crystal of 
beautiful smoky quartz (cairngorm) with long crystals of black 
tourmaline permeating the interior. Crystals of tourmaline are 
of frequent occurrence in our granite area. Groups are sometimes 
arranged in stellar forms. Small crystals of colourless quartz 
are often found in the granite under examination. I have a 
large crystal of opaque smoky quartz which is said to have come 
from the Queen’s granite quarry, where black tourmaline is also 
found.

it < caleareo- 
(The line of the granite is generally N. E. and S. W. while 
the line of strike of the formation that succeeds or abuts is gene- 
rally E. and W.) 
While all the members of this series are readily recognisable 
no line can be drawn as a separating line, they all pass into each 
other insensibly, gneissoid into micaceous and argillites, argillites 
into quartzites and quartzites into caleareo-quartzites, e. g., 
Examining the Queen’s quarries on the W. Side of the N. W. 
Arm, we first find the two formations in contact. Abutting 
against the granite we have a micaceous-schistose rock with 
distinct bedding, E. and W. strike and North dip, I generally 
try to secure a specimen at a junction of this kind so as to illus- 
trate it, I did not succeed here, the granite and the schist always 
separated. This rock passes into the hard gneissoid (ironstone) 
of the quarry. On the East side of the Arm, at Point Pleasant, 
we have the same becoming a coarse ferruginous and argillaceous
