_ rarely observed in it or its matrix; but they both contain 
small quantities of iron pyrites. It yields, by fusion, from 
60 to 70 per cent. Although these localities are distant 
from each other at least 40 miles, yet, as there is a great sim- 
ilarity between the ore from each, and they exist in the same 
range of mountains, running in a N. E. and S. W. direction, 
there is not the least doubt that they ultimately unite and 
form ene continuous vein. ’ 
At Digby Neck, about a mile east from the greenstone 
precipice, magnetic iron ore occurs in detache 
which are often hollow, containing octahedral crystals, vari- 
ously modified by secondary planes. At this locality, no 
regular vein has been met with, although many attempts have 
been made to discover one by digging. The masses are 
evidently out of place. Specular iron ore also occurs with 
it in masses of a laminated stratum, mixed occasionally with 
quartz and feldspar. They are both rich ores. 
In the North mountains, about § miles from the town of 
Digby, is a deposit of the magnetic iron ore, in large 
associated with greenstone. When I first found this locality, 
I considered it to be part of a vein; but as the ore was 
shortly afterwards removed and conveyed to the smelting 
furnace, it proved to be merely an assemblage of weighty 
wn as it were into a hollow of the mountain. 
Subsequently, on examining the spot, and the land adjoining, 
not the least signs of more ore could be discovered, the com-— 
pass not being in the slighest degree attracted. Amethyst, 
in beautiful crystals, varying in colour from deep violet to 
nearly white, occurs with this ore, generally in the form of an 
incrustation over the masses; but sometimes in their interior 
constituting druses. Also, ribbon agate and detached crys 
tals of transparent quartz. 
At Clements, in the vicinity of the furnace, are found 
crystals of chabasie, mesotype and heulandite, associated 
with analcime, and small globular masses of stilbite, which, 
when broken, present a foliated or radiated structure, and 
iron, without. any tendency. to crystalize, or in the form of 
the whole forming apparently an immense rock, the
