of a coarse quartzose conglomerate, and appears to be a soft bluish 
shale, enclosing in some places abundance of ferns and other plants. 
Wherever there are any traces of woody fibre, the copper appears to 
have been attracted to them ; but the largest quantity of ore has been 
obtained in small nodular concretions, the centre of which is some- 
times composed of vitreous copper and the exterior of copper pyrites, 
or the reverse; whilst a few nodules have been found to consist 
wholly of vitreous copper, and a still fewer wholly of pyrites. Some 
portions of the shale give out, on being broken, a most powerful 
garlic or arsenical odour. 
At the Capes, about ten miles east of Bache the sandstones con- 
tain thin beds of coal, and the greater part of the plants which ac- 
companied the paper was obtained from them. The coal is bitumi- 
nous and stated to burn well; but the quantity is too small to be 
worked profitably. On the beach Mr. Henwood noticed enormous 
quantities of nodular iron-stone, though he was able to discover in 
situ only a few in one of the beds of sandstone. 
Towards Belle Dune, on the coast of Chaleur Bay, hummocks of ser- 
pentine, traversed by small veins of steatite and calcareous spar, rise 
through the sand; and ina few places beds of sandstone and conglo- 
merate, assuming a flinty character, are in contact with the serpentine. 
Some of the strata of conglomerate are displaced or heaved by certain 
joints; but other joints traverse the strata without displacing them. 
At Chambers’s, near Belle Dune Point, is a quartzose ferrugimous 
limestone, which contains remains of Favosites polymorpha and other 
corals. The beds ‘strike about N.E. and S.W., and dip 20° S.E. 
At Dumerisque’s on the Ristigouche, near Dallsusies the western 
extremity of Chaleur Bay, Mr. Henwood observed a series of strata, 
extending less than a quarter, of a mile in length, and bounded by two 
trap dykes, beyond which he was unable to detect any traces of the 
beds. The strike of the strata was nearly N.E. and S.W., and dip | 
from 40° to 50° towards the 8.E. 
The following ascending sectional list is given by the author: 
1. Lowest bed, impure limestone, containing species of Cyatho- 
phyllum, Favosites, and Syringopora, also crinoidal remains. 
2. An impure limestone not very well exposed, but it contains 
Favosites Gothlandica, Producta depressa, Atrypa aspera ? 
3. Calcareous shale abounding with Producta depressa, and yielding 
also a species of Cyathophyllum and of Favosites, likewise Atrypa 
aspera. 
4. Calcareous shale, distinguished by the author as the Trilobite 
bed, on account of the remains found in it. In addition to the un- 
determinable portions of Trilobites, Mr Henwood procured specimens 
of Producta depressa with fragments of Orthocera and other Testacea. 
5. Calcareous lower earthy shale, in which Producta depressa and 
other shells and Crinoidea are stated to be abundant, but corals few 
in number. 
6. Earthy shale, containing numerous specimens of Favosites, cri- 
noidal stems, Producta depressa, Leptena euglypha, Atrypa aspera, and 
several of apparently unnamed species.
