abruptly from the shore of St. Mary's Bay. This jasper is 

 frequently of a fine texture, and is banded by stripes of vari- 

 ous colors. Sometimes it appears to have been made up of 

 rounded fragments of red jasper, cemented by chalcedony, 

 thus being converted into brecciated agate ; but this is not 

 uniformly the case, for the fragments are more frequently 

 encrusted with druses of quartz, which unite them to each 

 other. Cavities of considerable size are found in these 

 masses of jasper, having their interior surfaces lined with a 

 covering of crystallized quartz, which, projecting in stalac- 

 tites from the superior part of the geode, to which they are 

 attached by a slender neck, hang down into the centre, hav- 

 ing the dependent extremity enlarged by a radiation of crys- 

 tals. Small portions of jasper are frequently included in the 

 crystals, and give a beautiful appearance to the specimens. 



Amethyst is often contained in these cavities, and is of 

 such beauty as to attract the attention of the people, for we 

 found they had carefully preseved those specimens which 

 were of prepossessing appearance. Calcareous spar, in a few 

 instances, was found enclosed in the jasper — likewise chab- 

 asie of a dirty white color, but the crystals were of consider- 

 able dimensions, and regular form. 



On the coast of the Bay of Fundy, about six miles east of 

 Sandy Cove, is an inconsiderable indentation, known by the 

 name of Trout Cote. It presents but few interesting min- 

 erals. The situation of the rocks, however, is picturesque. 

 The columnar trap is recumbent on amygdaloid, which here 

 exists in a very narrow and almost inaccessible bed at the 

 base of the precipice ; the rocks have been tumbled in 

 great confusion against each other, forming rude irregular 

 passages under their walls. The only minerals to reward the 

 collector for visiting this place, are some varieties of agate, 

 which do not occur elsewhere on Digby Neck. They 

 have a ground of highly translucent chalcedony of a blue 

 color, with angular fragments of red jasper included. It 

 is of a very fine texture, and improves much on the lapi- 

 dary's wheel, and constitutes beautiful specimens of this cu- 

 rious variety. The chalcedony has sometimes, imbedded in 

 it, slender threads of blood red jasper, which accompanying 

 several different shades of color, twisted in zigzag directions, 

 and preserving its parallelism with the others, constitutes a sin- 

 gular combination of fortification agate, and bloodstone in the 

 same specimen — the outworks of the fort being delineated
