75 NOTES ON GEOLOGY AND BOTANY OF DIGBY NECK — BAILEY. 



Iron ores are both the most alundant and most incercstin^ 

 of these minerals. Tliey occupy veins tiaversingc tlie trappean 

 rock, and with a tendency, apparently, to lun in noi'th and 

 south directions. They occur at many points, the most promi- 

 nent hein^ alon^ the road from Di<(bv to Pi^Viy Lifjht, NiciioU's 

 mine in Rossway, Johnson's mine in Waterford. and Morehouse's 

 mine on the 8t. Mar^-'s Day 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 sujall 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 cr3'stalline, being partl}^ magnetite and 

 partly hematite. Fine crystals of rnartife or octahedral hematite, 

 probably a pseudomoi-ph of magnetite, are especially abundant 

 at Johnson's nn'ne and near Sandy Cove. The mining never 

 proceeded beyond the digging of sliallow trendies in the side of 

 the hills, and these are now lari^elv filled with rubbish; but it is 

 among the hitter that the most intciesting specimens, both of the 

 iron ore and of the associated minerals, are to be had. 



Among these associated minei'als quartz is \iy far the most 

 abundant, rock crystal being especially connnon and of great 

 variety and beauty. Amel/iyxfs are less common, and are now 

 hard to obtain, but very beautiful specimens were disclosed 

 during tlie opening of the trenches, and are occasionally met with 

 in l)oulders on the hillsides, oi- upon the beaches. With these 

 varieties of (juartz, and othei's such as agate, chalcedony and 

 jaspei*, are often tVmnd one or more of the zeolites, and many 

 specimens have their beaut}' much enhanced by the curious way 

 in wdiich the iron ore, rock crystal or amethyst, the zeolitic 

 ininerals, and, it may be, white or yellow calcite, are commingle'] 

 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
