70 Notice of a Locality of Zeolites. 



No. 2, on the north side, is a continuation of this vein, as far 

 as can be judged from its direction and inclination, and is per- 

 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 calc-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 calc-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 calc-spar, from which 

 handsome specimens have been obtained. Besides several of the 

 common forms, I found it in thin crystalline tables. Yery 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 iew 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 (?) 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 calc-spar, from 

 which several finely crystallized specimens have been procured. 

 It is in the form of large rhombs. A few specimens of very good 

 datholite were also procured from this vein.
