by this blood red zone. The agates occur, constituting veins 

 in the columnar trap, which are seldom more than three in- 

 ches wide. Chalcedony, of a very fine texture and smooth 

 surface, and on recent fracture, of a perfectly pure white, 

 also occurs at this place. It occurs, like the agates above 

 mentioned, in veins rarely more than an inch wide, in the co- 

 lumnar trap. This variety, on account of its fine texture 

 and good color, appears well adapted to be worked into 

 cameos and other articles of ornament. 



The next place which we visited on the coast of the Bay of 

 Fundy, is a cove, which has received the singular appellation of 

 Gulliver's Hole. This cove is the largest indentation which 

 the seas have been able to effect, on the iron bound coast of 

 the Bay of Fundy. It penetrates about three fourths of a mile 

 into the land, and being narrower at its entrance, which is 

 protected by massy columns of trap rocks, it affords a secure 

 retreat to the small fishing vessels which frequent these 

 waters, when the wind is too violent for them to ride on the 

 unsheltered coast. This locality will prove of interest to the 

 mineralogist, on account of a curious variety of stilbite, 

 which here occurs incrusting the walls of narrow, but deep 

 and perpendicular fissures in the trap. On either side of 

 these chasms, the stilbite occurs in compressed laminas, pro- 

 jecting horizontally, or at right angles with the rock to which 

 they are attached, for the distance of about an inch. They 

 are crystallized, at their free extremities, in the form of the 

 right rectangular prism, terminated by pyramids, and with 

 numerous other modifications. The crystals are arranged 

 in a very irregular manner, crossing and intersecting each 

 other at right angles, so as to produce between them, cellular 

 interstices of various forms. The color of this stilbite is white, 

 with a slight tinge of grey — it is glistening and somewhat 

 pearly on cleavage — before the blowpipe it melts easily into 

 a porous glass, without color and transparent. Large sheets. 

 of this mineral are easily detached from the rock, by means 

 of the hammer and chisel — they constitute remarkably fine 

 specimens of this singular mineral. 



Magnetic iron ore in veins about a foot wide, associated 

 with jaspery red iron ore, occurs in the trap rock at this 

 place; but as the veins are exceedingly irregular in their 

 course, and often terminate abruptly, little dependence can 

 be placed upon them for mining. — This remark will apply 

 to all the veins of iron ore which we discovered on Digby
