102 SIXTEENTH BEPORT ON THE CABINET OP NAT. HISTORY. 



appear on tlie ea.st side of Courtney bay, near Little river, 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 gradually 

 diminishes in ascending. 



No rocks newer than the above are seen at Carlton, or in the city of St. 

 John ; but near Little river, 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 ; exhibitinjg first, in 

 ascending order, grey sandstone and grit, with dark shale holding fossil 

 plants, among which is Galamites transitionis. This may perhaps be regarded 

 as the top of the group last mentioned. Above it, and passing into it at 

 their base, are reddij^h sandstones, grits and conglomerate, alternating with 

 green, greenish grey and red shale. Resting on these is a thickbedded coarse 

 angular conglomerate, succeeded by evenly bedded shales, shaly sandstones 

 and grits of dark-red and purplish colors. These are the highest beds seen, 

 as beyond this place they are bent in a synclinal, and reappear with re- 

 versed dips. 



Another most important observation of Mr. Matthew is that near 

 Bedhead the member of the St. John series last described is overlain un- 

 conformably by a conglomerate similar to that of the Kennebeekasis, and 

 probably the Lower Carboniferous conglomerate. It dips to the northwest, 

 or in the opposite direction from that of the underlying beds, at an angle 

 of 80° ; but Mr. Matthew regards the dip as due in part to false bedding. 



The whole of the deposits above described maybe summed up as follows, 

 the thickness stated being from measurements and estimates made by Mr. 

 Matthew, and to be regarded as merely approximate* (See figs. 1 & 2). 



CARBONIFEROUS SYSTEM. 



Feet. 



Coarse red conglomerate, with pebbles of the underlying rocks, and con- 

 stituting in this vicinity the base of the Carboniferous system. 



DEVONIAN SYSTEM (OR PERHAPS IN PART UPPER SILURIAN). 



1. Dark-red and greenish shales; flaggy sandstones and grits; coarse an- 



gular conglomerate 1850 



2. Reddish conglomerate, with quartz pebbles; reddish, purple and grey 



sandstones and grits; deep-red, grey and pale-green shales. A few 

 fossil plants " 2350 



3. Blackish and grey hard shale and arenaceous shale; buff and grey 



sandstone and flags. Many fossil Plants; Crustaceans and Spirorbis, 2000 



* 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 Kennebeekasis river to the 

 extremity of the peninsula on which St. John stands. The sections 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 ascertained by Mr. Matthew towards 

 the Mispec river.
