Shite: TRIASSIC (?) ROCKS OF DIGBY BASIN.—BAILEY. 
following the former along the shore for a short distance they 
are found, after becoming gradually harder and somewhat 
vesicular, to terminate abruptly along a vertical line, which would 
appear to be a line of fault, the only rocks seen beyond it, but in 
loose blocks, being composed of trap. 
From a review of the above conditions it would seem to be at 
least possible that the red and purple beds, which are undoubtedly 
a part of the group usually referred to the Trias, are more recent 
than the neighboring traps, unless indeed there were several 
periods of eruption, between or during which the stratified rocks 
were deposited, and then received their burden of trappean 
fragments. 
We have now to notice another section in which facts of a 
similar character are stili more clearly exhibited. 
This second section is found in the town of Digby, just below 
the point where the track of the Dominion Atlantic Railway, in 
taking the direction of Bear River, runs along the top of aseries 
of low blutts overlooking the Annapolis Basin. One of them, 
about twenty feet high, is nearly vertical and almost wholly 
composed of rock, exhibiting the arrangement reproduced in the 
accompanying diagram, (See Plate X, Fig. 1.) 
At the summit are about two feet of soil, consisting of a 
reddish sandy loam. ‘This rests upon a bed which in texture 
resembles a coarse gravel, but with the pebbles contained in a 
matrix which, while sandy, is compact, and bleached to a hght 
grey colour by the action of humus acids from above. The pebbles 
in this bed include traps similar to those of the North Mountains, 
both erystalline and amygdaloidal, besides granite and slate ; 
and, as in the case of some of the beds on the Granville shore, 
they suggest a Quaternary origin. But directly beneath is a 
bed of reddish grey sandstone, several feet in thickness, which 
as clearly belongs to a much earlier formation, and in one par- 
ticular only differs from the ordinary red sandstones of the 
Annapolis valley. Jt also contains, but not uniformly, blocks 
of North Mountain trap. Further, below this red sandstone 
bed, but at the northern end of the section, and merging into it,
