244 Messrs. Jackson and Alger on the 
habitants, and that a company was formed not long since, for the 
purpose of working it as an ore of copper. This mistake seems 
to have originated from the use of the mineral rod, which in 
Nova Scotia, as well as in New England, has led many an honest 
farmer into ruinous speculations. 
At this locality, we were kindly shown specimens of heuland- 
ite under a form, we believe, rarely presented by this mineral. 
One was a mass nearly cylindrical, twelve inches long and 
one in diameter at the larger extremity, and consisted of 
brilliant, transparent lamine placed at right angles to its axis. 
Its lustre was remarkably pearly, insomuch that it had for a long 
time been carefully preserved as a remarkably fine piece of 
“mother of pearl.” It was invested with a delicate coating of 
green earth, and seemed, as it were, to have been painted artifi- 
cially. It was found at St. Croix Cove, and obviously once filled 
the entire space of a cavity in the amygdaloid. We are induced 
to mention it, from its being a very perfect representation of the 
external form of this substance, as it occurs at that place. 
Gates’s mountain is very similar in its structure to the one just 
mentioned; but the minerals included in the amygdaloid are of 
a different character, and are so numerous as to render unneces- 
sary even the ordinary labor of obtaining them from the rock, 
which, by its decay, has here left them naked in the soil to an 
extent sufficient to give it a white appearance. Most of them 
are in small masses, not larger than a pepper-corn ; but among 
them were found globular masses of thomsonite and mesotype 
of the size of twenty-four pound balls. When broken through 
the centre, the masses of thomsonite present long and slender 
crystals, radiating from opposite points of the surface to the cen- 
tre, where they meet and form small cells, in which may be ob-
