NOVA SCOTIAN GEOLOGY—HONEYMAN. oF 
in age,—the Dolgelly gold being of Cambrian age, while the 
other was considered to be of Lower Silurian age. The researches 
and discoveries in the paleozoic geology of old Acadia—New 
Brunswick, Nova Scotia and Cape Breton—during the past 20 
years, have added Primordial or Upper Cambrian, Upper Lingula, 
Flags, Hudson and Trenton, with their characteristic forms of 
life. Every effort has been made, especially by diligent study, of 
the rocks Saint John and Halifax, to correlate our gold fields with 
the most ancient of the Paleozoic series. The old Igneous rocks 
have, to a great extent, been resolved into Archzean Metamorphic 
rocks—Laurentian and Huronian—so that the Lower Cambrian, 
or Dolgelly, auriferous period seems now to be the only resting 
place for our own auriferous series of rocks. The want of life, 
or its existence in low and doubtful forms, seems to indicate this. 
This view accords with the conclusion at which I had arrived by 
the lithology, sequence and paleontology observed in the Western 
Counties, especially of Digby and Yarmouth. 
CORRELATION. 
Previous investigations in Kings and Annapolis Counties, 
and especially at Nictaux in the latter, had vre-conducted to Dol- 
gelly and led to a correlation with the auriferous formation of 
Halifax County. In my unpublished paper, read at the same 
meeting, on the 12th of November 1877, that I read my published 
paper, “On the Geology of Nictaux,’ I made use of SALTER’s 
notes on READWIN’S Map and compared the Halifax Quartzites 
and Argillites with the “ Lower Cambrian,” “ Barmouth and Har- 
lech Rocks of Prof. S—pewick.” “The Dolgelly Gold district 
comprehends the upper part of the Lower Cambrian or Barmouth 
Rocks, and the lower part of the Upper Cambrian or Lingula Flags 
(Primordial), which range all along the Barmouth estuary and 
thence northwards to Festiniog.” The whole series of these rocks 
(Barmouth) consists of a very hard sandstone with beds of purple 
slate, which occur chiefly in the middle and lower portions of the 
series, but the upper sandstone beds are frequently interstratified 
with bands of green slate which distinguish it readily from the 
overlying formation, viz:—The Lingula Flags or Upper Cambrian, 
. This is a triple formation measuring about 6000 or 7000 feet in 
thickness, according to Professor Ramsay. It has been divided
