as merely a rude approximation to the truth; and the colouring in 
many places, more especially in the interior, remote from the coast- 
lines, is little more than conjectural.” 
In various parts of ‘Acadian Geology’ reference is made to rocks 
which were thought by Dr. Dawson might be older than the Lower 
Silurian slates and quartzites (see particularly p. 620, ‘ Acadian 
Geology,’ 2nd edit.). These will probably now be classed with the 
Huronian series; and the massive porphyritic granitoid gneiss on 
which they rest, with the Laurentian. 
Dr. Sterry Hunt visited Nova Scotia in November 1867, “for 
the purpose of making some observations on the gold-bearing rocks 
of that Province, with the view of comparing them with those of 
other parts of the Dominion, and also of obtaining such information 
as might be useful in the event of a geological survey of Nova Scotia 
itself.” 
Dr. Hunt’s stay in the Province was limited to four weeks in the 
months of November and December; and in the descriptions which 
he has given in his official Report to Sir W. E. Logan*, he quotes 
the, following as the principal sources of information about the 
geology and mineralogy of Nova Scotia :—Dr. Dawson’s ‘Acadian 
Geology,’ Ist edit.; Mr. Poole’s Report, 1862; Mr. J. Campbell’s 
Reports, 1862 and 1863; Professor B. Silliman’s Reports on Tan- 
gier, Waverley, and Montagu Goldfields, 1864. Dr. Hunt’s opinion 
of the age of the gold-bearing rocks is expressed in the following 
paragraph :—“In the present state of our knowledge it appears 
probable that they may represent a part of the Lower Silurian 
Series, which, like the Upper Silurian and Devonian of this part of 
the continent, may be supposed to consist chiefly of non-calcareous 
sediments.” 
The Map (Pl. XXX. fig. 6) of part of New Brunswick between the 
Bay of Chaleurs and the State of Maine, ‘‘ showing the disposition of 
theGneissoid Series, part of which may be supposed to be of Laurentian 
age,” 1s reduced from the original manuscript map which accompanied 
my Report on the explorations in 1865, and is described with some 
detail in pages 42-50 of the Report. The lines of section show 
where I crossed the gneiss belts; but, the intervening country 
being a rocky and wholly unexplored wilderness, the continuity of 
the bands is purely conjectural. 
A copy of this Map was sent to Sir W. E. Logan in 1865; and 
allusion is made, in the ‘ References to the Atlas of Maps and Sections 
of the Geological Survey of Canada,’ to opinions expressed in my 
report that much of the granites of New Brunswick consist of altered 
sedimentary strata‘.

Scotia. 
t+ Much of what in Nova Scotia, New Brunswick, and Maine is represented 
on the Map as intrusive rock (chiefly granitic), probably consists of palseozoic 
strata altered zm situ, as already suggested by Dawson and Hind. See the 
latter’s ‘Report on New Brunswick,’ 1865, p. 50; ‘Atlas of Maps and Sections, 
Geological Survey of Canada,’ 1865.
