264 Messrs. Jackson and Alger on the 
specimens are very prepossessing in appearance, and would, from 
their resemblance, be mistaken for the crystallizations of sugar, 
which adorn the shops of confectioners. 
The stilbite occurs, also, in radiating groups of crystals, 
forming beautiful stelle, which are distributed through the en- 
veloping masses of calcareous spar. 
Many other minerals occur at Cape D’Or; but, since they 
are such as we have already mentioned as occurring at other 
places, we shall not here repeat the notice of them. 
Leaving Cape D’Or, we pass Spencer’s Island, which is situ- 
ated about a mile from this cape. It is composed of columnar 
trap, and adds much to the picturesque appearance of this region, 
although it presents no objects of natural history worthy of 
description. The altitude of this island is nearly equal to the 
diameter of its base, and standing alone, like a tower in the 
midst of the waters, it breaks, in some degree, the violence of 
the surge, which rolls into the Basin of Mines from the Bay of 
Fundy. 
Proceeding along the coast towards the east, up the basin, we 
pass the more tame scenery of the sandstone and shale districts 
to be described hereafter, and do not meet with the trap, until we 
arrive at Cape Sharp, which is fifteen miles from Cape D’Or, 
and about four from Cape Split on the opposite shore, with 
which it is shown in Plate II.* | The promontory of this 
cape is composed of the amorphous trap, which scarcely 
exhibits any traces of columnar arrangement. The trap forms 
* A nearer view of this cape, as it appears from the east and shows itself 
recumbent on red sandstone and shale, may be seen in Vol. XV. of Professor 
Silliman’s “ Journal of Science.”
