@oLOGY OF ANTIGONISH COUNTY—HONEYMAN. 321 
Considerable work has been done in the search for coal under 
the direction of John Campbell, Esq., of Dartmouth, N. S., who 
has reported the discovery of coal beds having an aggregate 
thickness of 25 to 30 feet. Work has been discontinued for 
many years. Not far from this locality there is a bed of lime- 
stone. Advancing further, four miles, we reach the conglomer- 
ates of the south side of the basin, at the back of the Antigonish 
Sugar Loaf. We have noticed the eastern extension of these at 
Melsaac’s Point and Cribbeau’s Head, in Section I]. . The west- 
ern boundary of the basin are the Arisaig Mountains, as already 
noticed, and the Antigonish Mountains of Section I. At the 
back of the former and the beginning of the latter, as the road 
from Arisaig Pier and Brook descends into Pleasant Valley, 
Lower Carboniferous limestones are seen outeropping. Fine 
exposures of conglomerates and coarse grits are seen in Right's 
River. Black shales outcrop in the “Big Marsh,” on the “Old 
Gulf Road.” Sandstones outcrop in all direetions, and in Ma- 
lignant Brook before we reach the cove, and Section II]. To 
the west of this brook hills are seen in the rear of McNeil’s 
Mountain. These are formed of conglomerates belonging to the 
west side of the basin. 
Crossing the mountains of the section, at a distance of half a 
mile, we find an axial series of igneous rocks. We have already 
inet these at St. George’s Bay, Section IJ. They also outcrop to 
the west ina bluff on Right’s River. The central rock of the 
“Sugar Loaf” is Archean (vide “ Polariscopic Notes”). The 
rocks of these mountains, with the exception of the igneous 
rocks, are of Lower Silurian age (/). With the igneous rocks; 
they are analogous to McLellan’s Mountain; Pictou County. Two 
miles farther we come to their south side, and to the north side 
of the southern Carboniferous area. A little farther we reach 
Section I, Line of Railway. Proceeding further (18 miles) we 
pass through this area with its conglomerate sandstones, gyp- 
sums and saltsprings, limestones, ochreous and non-fossiliferous. 
To the west there are great beds of gypsum. On a small tribu- 
‘tary of the Ohio River there is an interesting limestone replete 
with Lower Carboniferous Brachiopoda. It is one of the two
