NOTES ON GEOLOGY AND BOTANY OF DIGBY NECK—BAILEY. 75 
Iron ores are both the most abundant and most interesting 
of these minerals. They occupy veins traversing the trappean 
rock, and with a tendency, apparently, to run in north and 
south directions. They occur at many points, the most promi- 
nent being along the road from Digby to Digby Light, Nicholl’s 
mine in Rossway, Johnson’s mine in Waterford, and Morehouse’s 
mine on the St. Mary’s Bay shore near Sandy Cove. At several 
of these points attempts have been made to remove the ore, and 
considerable money has been spent, but the small size of the 
veins and the cost of removal have in all instances prevented 
them from being remunerative. The ore is sometimes massive, 
but more generally crystalline, being partly magnetite and 
partly hematite. Fine crystals of mavrtite or octahedral hematite, 
probably a pseudomorph of magnetite, are especially abundant 
at Johnson’s mine and near Sandy Cove. The mining never 
proceeded beyond the digging of shallow trenches in the side of 
the hills, and these are now largely filled with rubbish ; but it is 
among the latter that the most interesting specimens, both of the 
iron ore and of the associated minerals, are to be had. 
Among these associated minerals quartz is by far the most 
abundant, rock crystal being especially common and of great 
variety and beauty. Amethysts are less common, and are now 
hard to obtain, but very beautiful specimens were disclosed 
during the opening of the trenches, and are occasionally met with 
in boulders on the hillsides, or upon the beaches. With these 
varieties of quartz, and others such as agate, chalcedony and 
jasper, are often found one or more of the zeolites, and many 
specimens have their beauty much enhanced by the curious way 
in which the iron ore, rock crystal or amethyst, the zeolitic 
minerals, and, it may be, white or yellow calcite, are commingled 
or disposed in alternating layers. 
It is of little use to name definite localities for these minerals, 
other than the mines alluded to above, for the finding of speci- 
mens is largely a matter of chance and of diligent search. It 
may, however, be mentioned that the rocks near the light house 
in Tiverton (Petite Passage) are especially noticeable for the
