 oner. Construction will begin upon
 the completion of the negotiations
 now underway with the Federal and
 State governments, and will represent

 Fred Dennett, a former commits
 sioner of the general land office, is
 the attorney in charge of the land
 end of the enterprise. Recently he
 explained the purposes of the Phila-
 delpnians to the members of the Ari-
 zona Land Commission. At his re- quest the commission has filed an application with the United States Land office for the withdrawal of
 l7,600 acres of land suitable for agri- cultural purposes below the dam site. The petition was rendered under the terms of the Carey Act.
 Four hydraulic giants, the first to he installed in the Lynx creek field, will be in operation next week at the property of the Wichita Placer Com pany. The plant is semi-hydraulic in cnaracter-heavy pressure pumps established near the dam forcing water to the giants, instead of a pressure being obtained by the grav- ity method customary in hydraulic mining. A water supply ample for continuous placer mining operations has been conserved in the company's cam, and two sets of sluice boxes each 40 feet long and in four sections are in place. J. w. Alderson is in charge of the giants. Alderson, who for many years was in charge of hydraulic mining plants at Leland, Oregon, states that the holdings of the Wichita Placer Company are rich Tn gold and that the venture IS an as sured financial success.
 Colorado capital is invested in the Fl Dorado Company. corporation that began placer mining operations on Upper Lynx creek late last Fall. The Wichert Mining Company is operating successfully in the Hassay- ampa field through the medium of a conveyer system of handling the gravel and the utilizing of a wet washing process to recover the gold Plans are likewise well advanced for establishing big dredge on tne Hassayampa for placer purposes. Ten men arc now employed in testing the auriferous areas on four large ranches which were recently purchas- cd by the promoters of the enterprise.
 The heavy snowfall of late Decem- Der assures a supply of water for ground sluicing purposes for many months. Encouraged by the pros pect. the smaller operations along Lynx creek and elsewhere are getting their ground in shape for immediate working. In former years Lynx creek, as a rule. has supplied very limited amount of water, with the re- suit that the areas prepared for the simpler processes of ground sluicing have been small. The current year, however. much larger areas are being prepared under conditions whicn in dicate very satisfactory cleanups for the season. Fifteen placer mining parties have established their. camps along the creek. and others are out fitting in Prescott tor the same field.
 Within the last few months num- Der of representatives of outside cap ital have investigated the gold-yield- ing possibilities of the county's plac CT areas and nave reported favorably thereon to their clients. Among them is w. H. Jones. who has just com pleted a fve-week's inspection of the large placer acreage owned by Shu- mate and partners in the Quartzsite country. Jones Is much gratified with the results of his tests, has made favorable report to his employer. and anticipates the early consummation of deal that will involve placer min ing operations on an extended scale
 Davidson Markham. representing a San Francisco firm that manufactures an electromagnetic device for separ- ating gold from gravel, is making ex- haustivc tests in the various placer fields of Yavapai county. At present ne is investigating the possibilities of the Humbug creek section, south of Harrington. Upon the completion of his work there he will look over the placer areas tributary to Prescott. Markham is well satisfied with the result of the tests and investigations he has thus far made.
 Richards Cline, one of the best known mining engineers in the West. recently inspected a large placer area in the Walnut Grove section. An important deal hinges upon the
