54 NOVA SCOTIAN GEOLOGY—HONEYMAN. 
SECTION A, LONG. 63 deg. 35 min. 
From Cape Sambro the Archzeo-Cambro Silurian (lower) 
extends 34 miles, 14 miles of Lower Carboniferous succeeds when 
we reach the Schubenacadie River. North of this is Hants 
County. 
SECTION B, LONG. 63 deg. 20 min. 
From Three Fathom Harbour the Archzo-Cambro Silurian 
(lower) extends to Gay’s River Road, a distance of 28 miles, the 
Lower Carboniferous succeeds and extends a distance of 20 miles 
to the vicinity of Truro, then comes the Triassic. Beyond are 
the Carboniferous, Silurian and Archzean of the Cobequid Mount- 
ains which do not come within the scope of our Paper, as the 
Pictou Railway line is our boundary in this direction. 
SECTION C, LONG. 62 deg. 55 min. 
From Clam Bay the Archzeo-Cambro-Silurian (lower) ex- 
tends 47 miles to Cox’s Brook, a tributary of the Stewiacke River. 
Succeeding this are 12 miles of the Lower Carboniferous, before 
we reach the Pictou Railway. 
The composite term Archzeo-Cambro-Silurian (lower) of the 
above sections, was first used in my paper “On the Geology of 
Digby and Yarmouth Counties.” Trans. It was there explained 
that Archwo-Cambro refers to Formation, and Silurian-lower to 
subsequent metamorphism with the introduction of gold and 
associate accidental minerals. The term “grossly cotemporaneous” 
has been used to characterize this. It seems to me that this is 
too indefinite and unscientific. My use of the term “Archzean” is 
that of Dana in his Text Book of Geology, where it is equivalent 
to the old term Azoic, and includes the Laurentian and Huron- 
ian formations. The Huronian seems to include the Lower 
Cambrian of certain English Geologists, SALTER and others. 
H. M. Geologocial Society does not recognize this sub-division of 
the Cambrian. I explained, Loc. cit., that I used the term Cam- 
brian as it is used by H. M. Survey. In my Paper I was led by 
fossiliferous evidence and sequence to regard the auriferous rocks 
of Yarmouth as of Pre-Silurian age, Cambrian in Formation, and 
to give them a lease of a portion of subsequent time for alteration, 
metamorphism and the acquisition of Gold and Gems, &e. The 
associated granites were prefixed to these and made participants
