mixture with the slate, from which it has been difficult to separate it. 
The cast iron obtained from this ore, is of good quality for strength 
and softness, while that of a harder nature, containing less carbon, 
is readily converted into malleable iron, which, to give it the 
praise it deserves, is equal to the best of this description made in 
the United States. The pure iron has also been converted into 
blistered steel, which, on trial, was found equally useful for the 
purposes to which the foreign article had been applied.* 
The fossil remains contained in this ore are not so numerous 
as at either of the localities before cited. But, besides their im- 
pressions, we have here presented more interesting traces of 
them, which strongly indicate the effects of heat both upon their 
fleshy and crustaceous parts, in decomposing and converting them 
into the substances which are now presented in the ore. But 
we shall allude to this more particularly, after stating the fossils 
which were recognised. They are terebratulites, ammonites, tel- 
lenites, encrinites, and trilobites. Of the last curious and, in 
Nova Scotia, hitherto unobserved fossil, supposed to have been 
originally a crustaceous insect, we obtained the remains of one, two 
and a half inches in length. It presents a series of transverse 
joints, divided vertically into three lobes, the central one of 
which is more prominent than either of the other two, and has near- 
ly the width of them both. They terminate at the lower part of 
the fossil, without showing the caudal projection observed in some 
species. The matrix, to which this fossil is attached, is a very 
compact mass of slate, passing on one side into magnetic iron 
* It is to be regretted that the Iron establishment erected in the vicinity of the 
iron mine at Clement’s in 1826, has since ceased its operations, as the country is 
now obliged to look to other quarters for the supply of an article which her own hills 
would yield her in an abundance almost unknown to any other.
