Joseph McGillvray Tells of
 an Ancient River Bed.
GREAT WATER SCHEME
Would Supply Ono Hundred and
 Forty Miles of Crooks and Ninety Miles of Benches-New London Company to Operate This Season.

Joseph McGlllvray, rugged mining ex- pert seventy three wears of age but who does not look over fifty, has been in town the last few days. on his way In to Daw- son. This will be his third trip in 10 the Klondike.
 This time he Is on his way from Lon don. where he has succeeded in interesting capital for the operation of q number of claims on Bonanza, near Fox gulch. These are bench claims and the company now has eleven and will purchase more. For those already purchased the money has been sent in to Mr. MeGillvray's son John, who went to Dawson in the first rush as correspondent of the New York Herald, and by him paid to the owners Of the claims.
 The price paid for these bench claims varies. the highest paid for any single claim being $40, 900.
 MrMeGlllyrav goes in now as the man. aging director of the new company, and has with him a secretary and bookkeerer for the concern.
 With the opening of navigation the company will ship in about I3c tons of freight, which will include the most mod ern machinery and plInt, and supplies for the camp. The company will employ at the start 100 men, and these will be board ed at the eompinv's camp at the mine by the company.
 MrMeGllyray found the English mark C, dull SO far as speculative capital was concerned. nothing dolns in short, owing to the war in South Africa. He Is there fore much elated that he was able to ob- tain capital for this company, which Is called the Anglo>Klondke Mining Com pany, as this Is the only Klondike enter prise taken up bv the London market dur ing the past season.
 Mr. MeGillvrav said last night; How came to go into the Klondike in the first place was because of what my son wrote me In regard to the lack of water for work lng ihs creeks, and, as have followed to mines in California, went to Dawson to look over the situation. On examina- tion, and after making certain surveys, | worked out a scheme that saw was prae- tieable. This was highly recommended by Mr. Ogllvle and took it to Ottawa to get the necessary commissions from the government. Then went to London and formed a syndicate and raised the capital to carry out the scheme.
 We proposed to supply all the creeks with water from the higher ranges of the Klondlke river; and we should begin with a supply of not less than 5000 miners inches. Less water than that would be of no use 10 the country wh ltever /. As the work progressed we should be able to sup ply 10000 miners inches, to carry on the mining there, which in my opinion, will last for generations. Our plan is to use Inverted syphons, and for these we would require about 1000 10 I5,ooo tons Of steel piping In the winter we should shut the water off and let the plant He idle.
 My s)n John Is the engineer in the Klondke tor several London companies, examining and reporting upon properties for them, and making purchases for their account"
 The scheme of the Anglo-Klondike Min ing Company, which Mr.,McGillvrav 50 successfully floated while In England, Is based entirely upon the conclusions he has come to as to the cause of the gold deposit in the Klondike, and as to the manner in which this deposit has been made. The claims on which the company begins oper. atlons are two hundred feet above Bonanza forks. and about eight hundred feet above the Yukon. They arc situated In what Mr. MeGilvray believes to be an old river bed, now a wide plateau, which was the great watershed of the district before the Yukon and other streams had cut their way through the gravel deposit ed by glacial action.
 He had this conclusion in view when he drew up his waterworks scheme. and some Idea may be formed Of the gigantic nature of thls proposition from few figures given out last night. The plan. he said. took In I4o miles of the present creeks, and ninety miles of the benches. As an instance of the water required, and the productive ex- lstence of these claims, he said that on Bonanzi there were TO miles of bench car rying 3s.ooo.ooo cubic yards of pay gray. el. Working rzo days year, and using $ 900 inches of water, it would take II7 years to wash out these benches alone.
