314 GEOLOGY OF ANTIGONISH COUNTY —HOUNEYMAN. 
George to Pictou County line.—At the Cape and westward, as 
far as “Arisaig Township” line, we have conglomerates, with a 
projecting trap-rock here and there, especially at the point of 
the cape. Beginning at the line, we find exposed on the shore, 
and up a brook, metamorphic slates of dark colour, with a thin 
bed of calcite. They seem to be identical with the rocks of the 
“Sugar-loaf.” We shall have occasion to refer to them again. 
These bring us to what I have, in former Papers, called the 
“Lower Arisaig” and “Archean Typical Series.” The first rocks 
of this series are (quartz) syenites, dark red, cream-coloured and 
white; they are finely granular, sparingly hornblendic, and sus- 
ceptible of a fine polish. Green feldspar occurs in these syenites. 
They are also traversed by veins of calcite, several inches thick. 
Succeeding these are strata of petrosilex. 'These are traversed 
by quartzite veins having mica. After these come steep cliffs 
of granited diorites, which project into the sea. We have then 
a bed of ophite and ophicalcite. They extend to the road south 
of the shore, where it outcrops. To a distance of nearly 24 
miles, there occur diorites, ophites, crvstalline limestones and 
ophicaleites (marbles), hornblende rock, hornblende and albite 
rock. (Vide Polariscopic Notes, No. 1. Paper preceding.) The 
last is the rock which produced the “boulders in the drift” and 
on the shore. (Vide Section I.) A line connecting this rock 
with the drift runs 8. 20 to 30 E. This is the course of trans- 
portation of amygdaloids, G&e., from Blomidon. (Vide Paper 
“Glacial Transportation in Nova Scotia and Beyond.” — Trans. 
Institute Natural Science, 1872-73.) Diorites of this series are 
also traversed by veins of snow-white calcite and quartz. 
When I discovered these in 1868, I considered them to be of 
“Laurentian” age. Sir W. E. Logan thought they were of 
“Quebee” age. Dr. Hunt’s opinion coincided with my own. In 
order to harmonize the two opinions, I have adopted the term 
“ Archzean,” which has been applied to the series under considera- 
tion in Dana’s Manual, last edition, and I thereby designate 
corresponding rocks. Boulders of these rocks, which first direct- 
ed my attention to the rocks themselves, succeed. After these 
are sections of “drift.” I regard these as something different
