NEW STYLE GOLD MACHINE
 WILL SOON REACH DAWSON

on DOmlQlOQ CIBGk- are DeluB pIC5C- cuted 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 gulche3 and conveyed for miles in ditches. The ground is being prepared for opera tion with new type of machines Charles P. Dolan, superintendent for tho company on Dominion, who several weeks ago visited England, where the machines are being con structed, says one CT them was to have left there before the first of this month, and should be here with in a few weeks. It is to be taken to Dominion and assembled immed- lately on arrival Each ma chine will have a acpacity of about lO,SOO cubic yards a day, as much as the largest gold dredge in the KlOndike can handle. More exactly speaking the machine handles 45O cubic meters an hour, and a cubic meter Is a little larger than a cubic yard. They are known as the Lubecker dredge and eAcayating ma chine. Only one is coming at first so that if local conditions de- mand alterations of anI detail they can be made before the other ma chimes are forwarded.
 MT. Dolan, when in London this spring, made a special trip to Lep- sic, Germany, and vicinity, where he saw twenty-One of the machines in operation. Some were digging coal, some chalk, and others gravel and other material. All, he says, were working with entire satisfac- ton. The machines are mounted on railway tracks, and cAH move for ward at the rate of eight feet minute. For the purpose of pro vidiug a washer from the alluvial gravels to be excavated on the creeks near here, two parallel tracks will be used. The cXcavator will be on one track, and the washer on the other. It is not intended to use a grizzly for washing, but other devices will be used, and after the gravel goes through the boxes it will be pickeI up on the tailiug stacker and carried to the waste dump somewhat after the style the taiIings are disposed of by the modern gold dredge.
 The Lubecker machine weighs but 70 tons, and photographs of it give it the appearance of one of the large modern steam shovels, ex- cepting that on one side is the long arm of the excavator, and on the other the long arm 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 the depth of 70 feet below itself, or to a height of 70 feet above itself, and the number of buckets varies gccoding to the length necessary to reach. Heavy manganese steel lips will be provided on the buckets, 4nd confidence is entertained the machine will be able 10 dredge all the bedrock essential Sor the re- covery of gold, especially as the machine can move backwards and forwards over the tracks, takink off layers. It is not decided whether the machines, in their work here, will work along tracks placed on bedrock, or along tracks on the present surface, bat some have thought possibly it would be best to excavate first to bedrock, and then operate there, in which case the buckets would be dragging from Q point above the machine instead of from below. The low tracks are used a great deal in Germany.
 David Elliot, the shovel eXpert, who has been with 1lr. Treadgold for years, went to London last year to assist in plans for the Tread gold machines. He IS still there. Mir. Elliot is said to be one of the most expert shovel men ever in the country. Mir. Dolan, an old-time KIoudIRe operator and for the last several years in the hydraulic de- partment of the Treadgcld company, went to London to give advice as to the arrangements for the wash ing device, and to witness the operations in some of the machines now in actual use, and thereby have a working familiarity with them.
 If these machines prove all that it is hoped they will, they will mean a great stride in working small creek gravel deposits in the
