76 NOTES ON GEOLOGY AND BOTANY OF DIGBY NECK BAILEY. 



large number and varied coloration of the chalcedonic and agate 

 veins which traverse them. These are also found quite abun- 

 dantly through most of the rocks which border the Bay of 

 Fundy side of the peninsula, and among the blocks with which, 

 in places, this shore is strewn. Among the zeolites some fine 

 specimens, varying in colour from pure white to grey, flesh or 

 cream -colour, red and yellow, as well as of unusual form, were 

 obtained at Johnson's mine in Waterford, where also were 

 observed geodes or amygdules of amethyst and chabazite 

 enclosed in jasper of red and yellow tints. At Murphy's Cove, 

 upon the north shore, about eight miles from Digby, was 

 observed quite a large vein of Thompsonite. This has yielded 

 some beautiful groups of crystals, but it is somewhat difficult of 

 access, and has been to a large extent softened and decomposed 

 by exposure to the waves. At Mink Cove, on the south shore 

 of the Neck, in addition to a vein of magnetite, is found a small 

 vein of crystalline calcite, carrying some galena. In general 

 metallic ores, other than those of iron, are of rare occurrence 

 Native copper, it is true, occurs not un frequently, especially on 

 Briar Island, but, as far as known, only in the form of small 

 granules scattered through the trappean rock. 



BOTANICAL FEATURES. 



If to the physical and structural characteristics of Digby 

 Neck we add those of its relations, in contour and relief, to its 

 surroundings, it will be readily seen that these are of such a 

 character as must exert a marked influence upon the nature and 

 distribution of its native plants. 



It has been stated that the width of the peninsula is nowhere, 

 except at its head, more than two miles, and is generally less 

 Every portion of its surface is therefore more or less subject to 

 the influence of the adjacent waters, more particularly as regards 

 the prevalence of fogs. But while these latter not unf requently 

 enshroud the whole Neck in a dense and cool atmosphere of 

 rnist, the height of the ridge is such that its upper portions are 

 quite often bathed in sunshine, even though the shores and 

 adjacent waters may be wholly concealed from view. The fogs
