(See Plate IV.) At times the larger orebodies cross one another and form important junctions, althoughcontinuing a serpentinous course with little or no alteration oftheir mineral contents, and yet preserving their average strike. A typical plan of this occurrence can be seen on the Wellingtonand Huron Copper Bay sections, now being worked by the CopperMining & Smelting Company of Ontario Limited. The Bruce Mines, Ontario, 1846-1906. 159. A. Aphanitic Dyke, 25 feet wide. B. 20 C. 40 No. 1. Palmers Shaft, 360 ft. deep. 2. Brays or No. 2 Shaft, 450 ft. deep. 3. Rowes Shaft, 240 ft. deep. 4. Mitchells or No. 3 Shaft, 240 ft. deep. 5. Scotts or No. 4 Shaft, 340 ft. deep. 6. Crazies Shaft, 270 ft. deep. 7. Unknown. Depth about 75 ft. 8. CoUins Shaft, 200 ft. deep. 9. Gribbles Shaft, 200 ft. deep. 10. Knights Shaft, 210 ft. deep. The numerous shafts are relics of the time when hoistingwas done by a horse whim. Dolomitic Hmestone comes in at the N. W., and the northernportion has not been followed up. That on the south has beenexplored for 480 feet, by an adit parallel to the limestone. This gigantic horse, 1,500 feet in length, is crossed by threedykes, the material of which differs but slightly from the ordinarycountry rock. The centre one has not caused any alteration,but the other two are fracture planes and the entire mass ofground has been forced twenty feet to the north, throwing thelodes accordingly. Whil
