 The Treadgold mining operations on Dominion creek are being prosecuted this season along similar lines to those of last year, comprising thus far the washing of muck from the surface at several places with hydraulic giants. The water is being taken from several gulches and conveyed for miles in ditches. The ground is being prepared for operation with new type machines. Charles P. Dolan, superintendent for Che company on Dominion, who several weeks ago visited England, where the machines are being constructed, says one of them was to have left there before the fist of this month, and should be here within a few weeks. It is to be taken to Dominion and assem- bled immediately on arrival. Each machine will have a capacity of about 1O,80O cubic yards a day, as much as the largest gold dredge in the Klondike can handle. More exactly speaking the machine handles 450 cubic meters an hour. and a cubic meter is a little larger than a cubic yard. They are known as the Lubecker dredge and eXcavating machine Only one is coming at first SO Chat if local conditions demand alterations of any detail they can be made before the other machines are forwarded.
 Mir. Dolan, when in London this spring, made a special trip to Liepsic, Germany, and vicinity, where he saw twenty one of the machines in opera ton. Some are digging coal, some chalk, and others gravel and other ma terial All, he says, were working with entire satisfaction. The machines are mounted on railway tracks, and can move forward at the rate of eight feet a minute. For the purpose of provid- inc washer from the alluvial gravels to be excavated on the creeks near here two parallel tracks will be used. The excavator will be on one track, and the washer on the other. lt is not intended to use a grizzly for washing, but other devices will be used, aud after the gravel goes through the boxes it will be picked up on the tailing stacker and carried Go the waste dump somewhat after the style the tailings are disposed of by the modern gold dredge.
 The Lubecker machine weighs but TO tons, and photographs of it give It the appearance of one of the large modern steam shovels, excepting that on one side is the long arm of the evca- vator, and on the other the long ann of the stacker, like two huge wings. The digging is done with a series of buckets which drag inward to the machine proper. The machine digs to a depth of 70 feet below itself, or to a height 70 feet above itself, and the number of buckets varies according to the length necessary Co reach. Heavy manganese steel lips will be provided on the buck cts, and confidence is entertained the machine will be able to dredge all the bedrock essential for the recoveay of gold, especially as the machine can move backwards and forwards over the tracks, taking off layers. It is not de cided whether the machines, in their work here, will work along tracks placed ou bedrock, or along tracks on the present surface, but some have thought possibly it would be best to excavate first to bedrock, aud then operate there. in which case the buck cts would be dragging from a point above the machine instead of from
