Two Utah Camps.

At meeting few evenings ago of the Utah Society of Engineers there were some facts presented regarding two of the mining camps of Utah that are of general interest. The two camps under discussion by these en- gineers, eminently fitted by training and by personal work in the mines to speak of conditions, were Bingham and Park City.
 The history of Bingham was sketch ed from the time when the first claims were located in the fall of 1863, on to the day of the steam shovel operations and the big copper production of the present time. The wagon roads into the camp in the early days of eXis- tence, were later followed by a rail- road, with transportation facilities steadily improving as time passed on. The early day mining facilities were later improved, when electricity be- came the motive power, materially re ducing the cost of operatlon: within recent years, too, has come the steam shovel, handling immense quantities of ore at very small cost, and the in- vention of new milling and smelling devices, followed by the erection of great reduction works.
 During the thirty years between 1870 and 1900 the camp produced ore having a value of more than 75.000,- 000$. Since the latter date has come the development of the g eat p)rphyry deposits that have made this one of the big copper camps of the West. Today, statistics presented show, the camp is producing from 2S,0O0 to 34,- 900 tons of ore daily, has over 2OO,- 00O,0 900 tons of commercial ore avail able and is paying annual dividends of 5000, OO0$.
 The camp of Park City affords as in- teresting a history as does Bingham. The paper presented upon this camp stated that to date there has been taken from its mines 100000, ,O0O ounces of silver, l75, ,000 ounces of gold. 300. .OO0 tons of lead, 900,000 tons of cop per and 30, 900 tons zinc. The total output of these five metals had a money value of $500. '.O0OS of which 35, ,000. .000$ has reached the stockhold- CTS of the various companies in the form of dividends. The siver-lead ores here are described as occurring in Assure veins, or ih bedded deposits connected with Assures.
 Park City, with it's various classes of ores, has done much toward eyolv- ing new Ideas In ore treatment, The silicious ores prominent in the earlier | days of the camp called for special treatment. which was devised and proven successful. The sulphide ores presented another problem that was solved; and later came the heavier lead ores, bringing new concentration devices of value to the mining world Interesting to note, also, are the drainage facilities provided at this camp Adit tunnels drain the On tario Daily system to depth of 2,500 feet under the collar of the Daly- Judge shaft, as well relieving to some extent the water situation in the whole camp. The Anchor tunnel of the Daly-Judge and the Alliance tunnel of the Silver King each carry away near ly LOGO gallons of water per minute. in addition to the 5000 to 10000 gal Ions from the Ontario. Adits also reach the 800 and 900-foot levels of the Silver King shaft, the bottom of which is 800 feet above the Ontario tunnel.
 These are few of the salient points in the history and present conditions in two of the principal camps of Utah; the one copper camp, the other principally ver-lead.-Denver Min ing Record.
