This dredge was not a success on Cassiar bar,and the following year it was taken to pieces and brought toBonanza creek, where it was operated on Discovery and theadjoining claims both up and down stream. Though this wasnot considered a modern dredge, yet its operation on Bonanzawas successful, and demonstrated the possibility of low-gradeground being worked at a profit that could not otherwise beworked. In the siiiiiuier of 1905 the Canadian Klondike MiningCompany, Bimilcil, iiist;illc(| n htrge dicdgo on the Boylellviliiiiilic Concession, at the iiionlli of Hear creek. The ap-proxiniiilc cost of this dredge, including the power plant, wns$300,000. The dredge is second in size only to the mammolh. be <L be IDu o as MINIiSG 53 machine at Oroville, rnlifVu-nia, whicli handles more than3,000 cubic yards of earth daily. This one is expected underllie less favourable conditions presented by the frozen gravelof tlic Klondike to handle, in twenty-four hours, 2,000 cubicyards, digging 35 feet below the water surface, and throwingtlic tailings 22 feet high and back 90 feet. Each of the 05buckets weighs 1,700 pounds; and the grizzly, 27,500 pounds;and the spud, which steadies the barge from the stern, 10 tons;while many other pieces weigh from 6 to 8 tons each. Thehull nf the barge measures 100 by 33 feet. The electric poweris generated by three 150 horse-power boilers and a GOO horse-power Westinghouse-Parsons turl)iue engine. Last year thisdredge was operated 170 days. In California, where dredg-ing operations are carried on, a dredge can be operated 365days in the year. The fact that a dredge cannot be operatedin the Klondike during
