oken ore. The stoping is donefrom the top of the broken ore, enough being drawn to keep it aconvenient distance from the backs. The ore is run from thechutes into mine cars, which are trammed by hand to the stationwhere they are loaded on to the cage and hoisted. The manage-ment are now cutting ore pockets at the stations and propose toinstall a skip as soon as the ore pockets are ready. (For plansand elevations of these pockets see Plate II.) The shaft was sunk vertically in a large soft dyke, calledthe shaft dyke, and is well timbered. It is 5 x 8 clear of thetimbers, giving two compartments; one 4 x 5 for the cage,the other 4 x 2 in which the manway, air pipes, water pipes,electric wires and ladders have all been crowded. The timber,which is 10 x 10, is well preserved by the water, which is con-stantly running down the sides. This shaft is the only meansof entry or exit to the mine, and, as a consequence, the number Thk White Beah Mine - 531 LOHQ/TODfftAL SECT/ON NO J VEIN y^ f^\ ^

•Sc«./t Jo- Plate III. JiaH^y W^Ut 532 The Canadian Mining Institute of men the company may work underground is restricted byregulations in the Mining Laws of British Columbia. The management have decided either to make a connectionwith the Le Roi workings on the Black Bear claim or to make anupraise to the surface from some point in the workings. Thecost would be about the same for either. It would take about1,000 ft. of drifting from working No. 6 of the 850 ft. level (seePlate I) to connect with the Le Roi. The 1,050 ft. level in theLe Roi corresponds roughly with the 800 ft. level in the WhiteBear mine. The chief difficulty in making this connectionwould be the surveying. The surveyor would have to carry hisbearing for over 3,000 feet from a base line of not more than2—2\ ft. in length. This would render a connection with adrift in the Le Roi ground rather uncertain to say the least.Therefore, if this connection is attempted the drive will be aimedfor one of the large stopes.
