The following fossils were obtained from this quarry: 
undetermined ostracod, Strophomena incurvata (Shephard) ? 
Plectorthis sp., Maclurea logani Salter, Cyrtoceras constricto- 
striatum Hall. 
At a small escarpment along the road between lots 8 and 
9, Bucke township, just south of Dickson creek, dolomite similar 
to that of Farr's quarry furnished the following fossils: Re- 
ceptaculites occidentalis Salter, Zaphrentis small, crinoid columns, 
and Maclurea logani Salter. 
On the shore of Lake Timiskaming just south of Moore 
creek, and about 185 feet lower than the above occurrences, the 
following fossils were found: crinoid columns, Orthis sp., 
Rhynchotrema incequivalve (Castelnau), Murchisonia gracilis 
Hall. 
Of the above species Receptaculites occidentalis , Rhyncho- 
trema incequivalve , Maclurea logani , and Murchisonia gracilis 
are common in the Black River limestones of Alumette island 
in the Ottawa river (above Ottawa), as learned by a comparison 
with material from that locality in the collections of the Geo- 
logical Survey. Dr. A. F. Foerste has also found Receptaculites 
occidentalis and Maclurea logani in the Black River limestones 
of Cloche island, 1 and an undetermined Maclurea also occurs 
in the Black River rocks of Lake Nipissing. 2 Thus the Black 
River age of these beds is well established and their correlation 
with beds farther south and southeast is clear. 
The 250-foot section on the east side of Dawson point, 
where examined by the writer, is as follows: thin-bedded buff- 
coloured dolomites 20 feet above the normal level of the lake; 
talus slope of green shaly material mixed with dolomite up to 
110 feet; thin-bedded dolomites about 115 feet thick containing 
near their base Penlamerus oblongus Sowerby, Camarotoechia ? 
neglecta Hall? A try pa reticularis (Linnaeus); thick-bedded dolo- 
mites 25 feet thick containing numerous Niagara corals, some 
of which are: Favosites gothlandicus Lamark, Syringopora verti- 
cillata Goldfuss, Halysites catenulatus Linnaeus, H. catenulatus 
var micropora Whitfield, Zaphrentis stokesi E. and H. Thick-
