graphitic, abound in delicate vegetable remains, often in a very per- 

 fect state of preservation. These rocks appear on the east side of 

 Courtney Bay, near Little Eiver, at the extremity of the point of 

 land on which the city of St. John stands, and in the ledges and 

 cliffs on the shore westward of Carlton. In all these places they are 

 quite conformable with the underlying rocks, though the dip gra- 

 dually diminishes in ascending. 



'No rocks- newer than the above are seen at Carlton or in the city 

 of St. John ; but near Little Eiver a few beds of red shale and coarse 

 sandstone seem to indicate the commencement of a new member of 

 the series, the coast-section failing at this point. Mr. Matthew has, 

 however, succeeded in finding a continuation of the section further 

 inland, exhibiting first, in ascending order, grey sandstone and grit, 

 with dark shale holding fossil plants, among which is Calamites 

 Transitionis. This may perhaps be regarded as the top of the group 

 last mentioned. Above it, and passing into it at their base, are reddish 

 sandstones, grits, and conglomerate, alternating with green, greenish- 

 grey, and red shale. Resting on these is a thick-bedded, coarse, 

 angular conglomerate, succeeded by evenly bedded shales, shaly 

 sandstones, and grits, of dark-red and pui'plish colours. These are 

 the highest beds seen, as beyond this place they are bent in a syn- 

 clinal, and reappear with reversed dips. 



Another most important observation of Mr. Matthew is that near 

 Red Head the member of the St. John series last described is over- 

 lain unconformably by a conglomerate similar to that of the Kenne- 

 beckasis, and probably the Lower Carboniferous conglomerate. It 

 dips to the north-west, or in the opposite direction from that of the 

 underlying beds, at an angle of 30° ; but Mr. Matthew regards the 

 dip as due in part to false bedding. 



The whole of the deposits above described may be summed up as 

 follows, the thicknesses stated being from measurements and esti- 

 mates made by Mr. Matthew, and to be regarded as merely approxi- 

 mate* (see figs. 1 & 2).

* In my paper in the ' Canadian Naturalist,' I gave a sectional view of the 

 general arrangement, as observed on a line of section from the Kennebeckasis 

 River to the extremity of the peninsula on which St. John stands. The sec- 

 tions referred to in the text represent the same series, as seen on the east side of 

 Courtney Bay, immediately to the east of St. John, with the continuation ascer- 

 tained by Mr. Matthew towards the Mispec River.
