Mineralogy and Geology of Nova Scotia. 231 
Small portions of jasper are frequently included in the crystals, 
and give a beautiful appearance to the specimens. 
On the coast of the Bay of Fundy, about six miles east of 
Sandy Cove, is an inconsiderable indentation, known by the 
name of Trout Cove. It presents but few interesting minerals. 
The situation of the rocks, however, is picturesque. The colum- 
nar trap is recumbent on amygdaloid, which here exists in a very 
narrow and almost inaccessible bed at the base of the precipice ; 
the rocks have been tumbled in great confusion against each 
other, forming rude irregular passages under their walls. The 
only minerals to reward the collector for visiting this place, are 
some varieties of agate, which do not occur elsewhere on Digby 
Neck. They have a ground of highly translucent chalcedony 
of a blue color, with angular fragments of red jasper included, 
and are of a very fine texture; they improve much on the lapi- 
dary’s wheel, and constitute beautiful specimens of this curious 
variety. The chalcedony has sometimes, imbedded in it, slender 
threads of blood-red jasper, which alternating with several differ- 
ent shades of color, twisted in zigzag directions, and preserving 
its parallelism with the others, constitutes a singular combination 
of fortification agate, and bloodstone in the same specimen, — the 
outworks of the fort being delineated by this blood-red zone. 
The agates occur, constituting veins in the columnar trap, which 
are seldom more than three inches wide. Chalcedony, of a very 
fine texture and smooth surface, and, on recent fracture, of a 
perfectly pure white, also occurs at this place. It occurs, like the 
agates above mentioned, in veins rarely more than an inch wide, 
in the columnar trap. This variety, on account of its fine tex- 
ture and good color, appears well adapted to be worked into 
cameos and other ornaments.
