upon the latter must give place to those based upon the former; but 
we know of no Carboniferous marine forms in this region until a later 
time, for they are found in strata that overlie these shales. 
Horton Bluff. 
Not very far from the Gaspereau valley are the cliffs along the 
Avon R., known as Horton Bluff. Here a set of beds are exposed that 
contain in the finer layers much the same flora as is seen at the former 
place, but the beds are of coarser texture as they include flags and 
sandstone layers; the plants they contain are much broken and worn. 
Here occur Lepidodendron corrugatum and its variety cyclostig- 
moides; L. Gaspianum, L. Chemungense, and, perhaps, L. Sternbergu. 
Here also have been recognized Psilophyton princeps, P. robustius (and 
P. elegans?). Portions of the stipes of Aneimites Acadica are also com- 
mon. Some layers abound with spore cases which Sir William has 
referred to a Lepidodendron. ‘This assemblage of plants is as strongly 
Devonian in its facies as that of the Gaspereau R. 
Kennebecasis Valley. 
Sir William Dawson recognized the Albert shales as equivalent im 
age to the strata of the two localities above referred to. Now, these 
shales of Albert county have been traced by Prof. L. W. Bailey, Dr. R. 
W. Ells, and the author from the valley of the Petitcodiac R. across 
to, and down the valley of the Kennebecasis R. to Norton. Last year 
quite a considerable flora of fossil plants was found in strata holding the 
position of these shales in this valley, near St. John, by a party of the 
Geological Survey of Canada under the direction of Dr. R. W. Ells. 
These were submitted to the writer for examination. The material is 
rather coarse and the plants not so well preserved as those above 
described, and remains of ferns were rare, but Lepidodendra of several 
species were plentiful. Among these are LZ. corrugatum, L. Gaspianum. 
L. Chemungense, L. Sternbergii, L. aculeatum, L. rimosum. Stems of 
Psilophyton princeps are common, and a few spore cases occur, also 
broad and narrow strap-like leaves which may have belonged to Cordaites_ 
Detached areas of this terrane are found at intervals along the north 
shore of the Bay of Fundy, as far west as St. Andrews, N.B., and 
Perry, Me. At the latter locality remains of land plants were found 
many years ago in this terrane, which plants Sir William Dawson recog- 
nized as Upper Devonian; hence it would appear that the whole of 
this terrane on the evidence of the plants it contains, should be referred 
to the Upper Devonian, the base of the Carboniferous being found in 
the conglomerates and limestones with Lower Carboniferous marine 
fossils that overlie it. |
