sae et 
No. 2, on the north side, is a continuation of this vein, | s far 
as can be judged from its direction and inclination, and - 
fectly similar in its character, but in this place is larger, and has 
furnished several minerals which I could not find in the other, 
viz. brilliant crystals of iron pyrites, heulandite, laumonite, and 
several forms of cale-spar. ~The finest specimen of the stilbite 
of this locality was taken from this vein. It is a cavity in the 
carb. lime, finely crystallized, entirely coated with stilbite, which 
has crystals’of iron pyrites scattered over its surface, forming a 
beautiful specimen of about five inches in depth, by two or two 
and a half broad. : . 
No. 3, on the south side, is a vein of carb. lime with prehnite, 
of which only one small specimen could be obtained. 
No. 4, on the same side, and a few feet beyond the bridge which 
overhangs the rail-road, is a cavity which did contain epistilbite, (?) 
and from which a number of specimens have been taken, some 
of which are very fine. A blast was made, and the whole effec- 
tually removed, scarce a trace being left to denote the presence of 
the mineral. A vein of cale-spar runs up the cliff, and, at the 
bottom, covered with the soil, a specimen of the spar, in large 
rhombs, was obtained. It is sometimes associated, on the same 
mass, with the epistilbite, the latter in minute crystals covering 
the spar. 
No. 5, almost opposite, is a large vein of cale-spar, from which 
handsome specimens have been obtained. Besides several of the 
common forms, I found it in thin crystalline tables. Very minute 
crystals of iron pyrites are found on some of these specimens. — 
No. 6, just below No. 5, appears to have been occupied by veins 
of heulandite running along the greenstone, but which had all been 
broken up and carried away with the exception of the few speci- 
mens which we found. This place and the one before mention- 
ed, are the only localities known to furnish this mineral. 
No. 7, which is a short distance beyond, is a vein of soft, earthy 
matter, through which mesotype (2?) is disseminated. Higher up 
in the cliff, the same vein furnishes stilbite—rather indifferent 
however. ; 
No. 8, on the same side of the cut, is a vein of cale-spar, from 
which several finely crystallized specimens have been procured. 
It isin the form of large rhombs. A few specimens of very g 
datholite were also procured from this vein.
