NOTES ON GEOLOGY AND BOTANY OF DIGBY NECK—BAILEY. 73 
The traps, which form by far the largest and most conspic- 
uous element in the structure of Digby Neck, have been deseribed 
as varied, but the diversity which is seen is due rather to mere 
variations of colour and texture than to any essential difference 
of composition. And these variations seem to recur without any 
definite order, the colour even within a few yards often shading 
otf from grey, the prevailing tint, to green or purplish, while 
both in the coastal cliffs and in the interior, compact or columnar 
trap is associated very irregularly with beds which are scori- 
aceous or amygdaloidal. A good opportunity for the study of 
these rocks is to be had at Gulliver’s Cove, to the north of the 
sandstone section described above, here forming cliffs in some 
places 100 feet high. They exhibit layers dipping at a slight 
angle towards the Bay of Fundy, and are intersected by vertical 
veins from mere streaks to 4 or 5 inches in width. These 
consist of various silicious minerals, while those occupying the 
horizontal fissures appear to be chiefly zeolitic. The vertical 
veins have a strike about NNE. (magnetic). 
Other good exhibitions, especially of the columnar structure, 
may be seen about Digby Light and Broad Cove; bnt none are 
so remarkable as those afforded by the depressions of Sandy 
Cove and the Petite Passage. This latter truly wonderful gap, 
of which the northern entrance is shown in Plate VI, through 
which flows alternately a tidal current nearly 100 feet deep, 
and with a velocity at times of not less than 8 knots, is upon 
its western side, above the little fishing village of Tiverton, 
bordered and overlooked by beetling cliffs, of which the indivi- 
dual columns are most complete, and so carved by the sea as to 
exhibit in places all the aspects of human architecture. The 
boldness of the scenery is here further enhanced by the occur- 
rence of numerous large blocks of trap, often 20 or 30 feet in 
diameter, and of grotesque shapes, which are perched, sentinel- 
jike, upon the very edge of the bluffs, more than 100 feet 
above the water. These, if not “boulders of decomposition,” 
‘must have been derived from the trappean ridges which, though 
now invisible through submergence, are known to lie along the 
Bay of Fundy trough, outside of but parallel to the present coast.
