REVIEWS—GEOLOGICAL SURVEY OF CANADA. 465 
Mr. Richardson’s Report. The rock formations met with, comprise 
various beds belonging to the Lower, Middle, and Upper Silurian 
series, with the so-called Gaspé sandstone (a Devonian formation) 
the drift, and some eruptive rocks. The lowest recognised strata 
consist of graptolitic shales and sandstones of the age of the Hudson 
River Group. On the Patapedia river, the beds (probably Upper 
Silurian) exhibit well marked cleavage lines, independent of the bed- 
ding, and in places are greatly contorted. On the river Matanne 
in drift clay and sand, forming a terrace fifty feet above the sea level, 
Mya arenaria, Pellina Grenlandica, and Mytilus edulis, were found. 
The same species were seen at a similar level on the east side of the 
Metis river, whilst on the west side, at a distance of about two miles, 
and at a height of about 130 feet above the sea, Mr. Richardson met 
with Mya arenaria, and Saxicava rugosa. Hight miles up the river 
Metis, also, he observed the latter species with WNatica clausa and 
Balanus Hameri, 245 feet above the sea. Many terraces, contain- 
ing shells of these and other existing species, were found likewise 
on the Ste. Anne river and to the east of the Riviere du Loup. The 
economic substances observed by Mr. Richardson in his explorations 
are described in the following extract from his Report :— 
“The substances capable of economic application met with in the course of my 
investigations, were bog iron ore, wad or bog manganese, copper ore, chromic 
iron, serpentine, roofing slates, tile stones, flagstones, building stones, limestone 
for burning, mill stones, shell-marl, peat, and the water of mineral springs. 
* Bog iron ore. This ore was abundant in the second concession of the seigniory 
of Green Island, on the land of Mr. Félix Avril. About the middle of his lot it 
occurred in patches of from three feet up to eight feet in diameter, and from 
twelve to twenty inches thick. Between these patches there were intervals 
of thirty or forty paces. With a breadth that was not observed to exceed a hun- 
dred yards, the length of the area over which these patches were disseminated 
extended across ten lots, in the bearing S. 27 W., and half a mile, in rather less 
abundance, in a contrary direction. 
“Tn the seigniory of Cacouna at the village of La Plaine, on the lot belonging 
to Mr. Stanislaus Roy, a patch of the ore was seen, measuring fifty feet by fifteen 
feet, with a thickness of four inches. On the adjoining lot to the east, another 
patch of about the size of the previous one was met with; yellow ochre occurred 
in the same place in small quantity. 
“ Another locality was in the seigniory of Villeray, about three miles west 
from Green Island River. On the land of Mr. Narcisse Marquis there is a patch 
of the ore about 270 feet long, and from twenty to thirty feet wide, with a thick- 
ness of from six to twelve inches. The ore was likewise observed on several 
adjoining farms in smaller quantities, but, from the information I obtained from
