GEOLOGY OF ANTIGONISH ‘COUNTY —HONEYMAN. ‘oS 
from the drift of Section IT. While I regard the latter as the 
result of glacial (ice) transportation, J consider water as the 
agency‘ employed in the production of the former. We shall 
notice this again. At the Ceve solid rocks appear. Here we 
have an isolated pateh of Lower Carboniferous conclomerates. 
Originally this was doubtless connected with the other isolated 
patch of the same formation which oecurs farther west, on the 
aniddle and eastern branches of Doctors Brook. The associated 
and intervening igneous rocks evidently effected a separation. 
We find similar rocks dividing into parts and branches a band 
of an older formation, which we shall yet have occasion te 
notice. 
By the igneous rocks the conglomerates have been much har- 
dened and permeated. We therefore infer that the one is of 
more recent formation than the other. The igneous rocks also 
appear in a brook a little to the west. Drift then occurs until 
we reach MeNeil’s Brook. Here the first strata of the Fossilifer- 
ous Silurian series occur. Their second oceurrence in the section 
as at the eove west of Doctor’s Brook. From Arisaig Pier to 
McAra’s Breok they then eccupy the section. The other rocks 
an the seetion, from MeNeil’s Brook to Arisaig Pier, are a band of 
metamorphic rocks of Lower Silurian age associated with a great 
dyke of igneous rocks which extends into the sea, making the 
‘shore rocky and dangerous. 
At McAra’s Brook and beyond are Lower Carboniferous con- 
glomerates, grits and sandstones, with trappean ledges and seem- 
ingly intercalary beds, which have been much worn by the sea, 
frosts and ice. One great projecting mass of amygdaloid to the 
east of the brook, which was a bold and picturesque feature of 
the section twenty years avo, now has scarcely a vestige left. 
‘The seemingly intercalary beds of trap standing .out from the 
excavated sandstones are very striking. Near the county line, 
after an alternation of grits, sandstones and slates, there is a 
considerable bed of Lower Carboniferous limestones resting on 
‘slates, marls and a thin bed of limestone having oolitic structure, 
and characteristic Lower Carboniferous fossils. Still farther 
there are sandstones.in which I found, in 1868, two thin beds.of
