GEOLOGICAL GLEANINGS—HONEYMAN. 349 
traverses the centre of the Highlands, and then Carboniferous 
all the way to Whycocomagh, where it goes between the two 
great areas of Archean rocks, Cragneish and Mulloch. Another 
commencing at MclIsaac’s Pond passes through Loch Ban, and 
along the major axis of Lake Ainslie, and proceeds onwards 
to St. Patrick’s Channel, above the narrows ; extended farther 
it enters the Great Bras d’Or at 60° 55’ long., N. W. of Marble 
Mountain. It thus avoids the Archaean areas on either side 
of Lake Ainslie, and just touches the area at St. Patrick’s 
Channel. 
We also extend the glacial course on the west side of Lake 
Ainslie in the petroleum region. This in its extension to the 
Mabou Highlands passes into the Gulf of St. Lawrence, about 
half a mile north east of Sight Point. In the opposite direction 
it passes through the Archzan area on the west side of Lake 
Ainslie, and south of the petroleum region, and enters into Lake 
Ainslie. 
In our walks we have advanced as far north on the Broad 
Cove and Margaree roads as the Diorites, noticed in our intro- 
ductory description, and cross limestone strata on the Margaree 
road. Archean boulders have for some time disappeared, as 
we have been receding from the bounds of the Highlands. Our 
last specimens were collected some time before we reached the 
forks of the (Broad Cove and Margaree) roads. We had also 
crossed our sand hills twice, in the direction of Loch Ban, and 
made a collection of Archaean boulders on our way, in the deep 
ruts. In our second walk we advance aiong the top of the Loch 
to the right. A boulder was observed lying in our way, only 
here and there. At length we come within their range of trans- 
port, and found them sufficiently abundant and varied. We again 
commenced collecting. Coming abreast of a mountain on the left, 
we observed an outcrop of rocks high on its sides. We ascended. 
On our way Archzan boulders appeared in great numbers, con- 
tinuing up to the outcrop of rocks. These belong to Mr. Fletcher's 
Lower Carboniferous Metaphoric, and incline at a high angle. 
- When examining them, and looking for an appropriate specimen, 
we observe, right at the top, Archzan boulders. Of these we
