tomorrow by the application of new elements which bring about even better results than those boasted of the day da y before thus verifying and proving the old saying sayin that the world do move when benjamin franklin with his kite and brass key first subdued and harnessed the electric fluid for the use of coming generations no one ever dreamed that its application would eventually supersede supercede super supe cede reede wood coal fuel of all kinds and oils in the generation of power light and heat and it was not until a quarter of a century ago that the utilization of electricity for the purposes named came into general use and it was not until then th en that the importance of the discovery was realized and even then the value of this application was not fully comprehended but now that the t e worlds supply of fuel is becoming limited with every indication that in due time it will become almost exhausted the importance important im e and utility of the electric current is becoming more and more appreciated precia ted As a matter of fact electricity is rapidly supplanting steam as a motive power and is doing away with old time methods employed in the generation of light and of heat and not only is it proving more effective in these lines but it is also proving to be more economical and far more con convenient congenie venie rt r t ten years ago ag o the use of electricity was practically unknown in itah I 1 tab and the utilize ss tion of the electric fluid in our leading mining camps for power and light liast was barely in contemplation temp lation since then a wonderful transformation has taken p place ace in zion in neighboring cities and various minin mining districts in this intermountain region and now the streets and homes of our beautiful city are brilliantly illuminated b electric lights and street cars now move through our broad thoroughfares at a pace that puts to shame the methods meth of street transportation employed in anti electric days 1 1 I 1 f owr x J THROUGH THE SOLID ROCK PIONEER OGDEN improved street ear car service came hand in hand with the introduction of electric power at first this power was generated by steam but with the completion of the big cotton wood electric power plant and the harnessing 5 ses of this pretty canyon stream the current was v as generated by natural forces and at a far if 1 ss expense the cost being merely nominal after the installation of the companas comp anys fine plant with the success of this enterprise ent oprise fully assured it was not long until other ventures ventora 8 of the same character were inaugurated anaw the putting in of the itah plant below the big cottonwood works soon followed while oil hr installation of the pioneer power plant in ogden canyon was wag almost

surrounding peaks which rise to an eleva elevation tiow of from to feet above the sea level at the head of the canyon about feet above the sea level are several small lakes set in granite basins I 1 the water for the pig cottonwood power companas comp anys works is diverted from the stream at a point about three thre emiles nales from the mouth of the canyon into a small reer reservoir voir from this reservoir it is conveyed in a four foot steel pipe through a tunnel about feet long and thence down steep slopes to the power house the total head is feet the pipe delivers into a receiver four feet in diameter from which the water passes through curved cast iron pipes to the nozzles of the pelton water wheels there are six water wheels four of horse power each driving the main generators and two sm smaller aller ones for driving the ex exciting citino current dynamos the transmission line is fout fourteen teen m miles iles long the firs four miles is built over a rough mountain country the remainder is built along the county road the line as originally built consists of four circuits circuit S of three abree no 2 B S bare copper wires supported on borce porcelain lain insulators THE PIONEER WORKS the plans of 0 the company contemplate the alt ultimate amate utilization of the entire flow of the ogden rive to accomplish which to the best advantage will necessitate the construction of a large storage dam and reservoir at the upper end of the canyon and this storage feature forms the only portion of the system that is not yet completed at present a small crib dam with temporary head works has been built a short distance above the site of the large dam which gives the necessary head for filling the pipe but does not provide for any considerable storage of water the permanent storage reservoir when completed will cover an area of about 2000 avres acres and will have a capacity of nearly lS gallons A nine foot tunnel has been excavated through the solid rock around the south abutment of the dam which at ordinary stages of the river will be the sole outlet for the water in the reservoir about feet below the tunnel and connected to it by a rivet ted steel pipe ight eight and one half feet in diameter the main gate house is placed the main conduit is a pipe line with an internal diameter of six feet its total length is feet of which feet consists of wooden stave pipe and the last feet at the lower end of rivet ted steel piping there are eight tunnels in the rock the longest of which is feet also eight steel bridges with a total length of feet besides a timber trestle the maximum hydrostatic head on the wooden pipe is feet giving a pressure of fifty pounds per square squar inch einch the pipeline pipe line divides into two branches at the power house delivering into steel receivers laid on either side of the building g these receivers are six feet in diameter and are each provided with five two foot delivery pipes leading into the power house to the main water wheels and one fourteen inch pipe for the excite wheels the plant is designed for ten 1000 horse power water wheels and generators five on each side of the building only five of these are installed at present the transmission line is s thirty seven miles long and consists of two circuits of three no 1 B S bare copper wires the current reaches this city at a potential of volts and is reduced to the ordinal 2300 for local distribution one of the most interesting features of this plant is the immense seventy two inch value placed at an elbow of the steel pipe line about feet from its junction with the booc wooden len conduit this valve measures eight ei ht feet in height 11 and four feet from face to face of flanges and is twenty four and one half feet in length it has a total weight of pounds and twenty four horses were required to move its heaviest piece bece ll 11 IN PROVO CANYON the telluride plant is situated siti fated in the provo canyon a long and narrow defile between limestone mountains this plant is not a large one but it is remarkable in that it is operated at the highest voltage vol yet put to commercial use the first plant built by this company was at telluride colo and it was there that much of the pioneer long distance transmission engineering work in this country was performed the present plant in the provo canyon is temporary only and plans are now being drawn whereby it will be considerably sider ably increased in size and capacity of output the water is diverted by means of a tim her ber and rock crib dam about sixteen feet high into a half round wooden sterling flume built on the same principles as a wooden stave pipe this flume is about one mile long and delivers into a wooden stave pipe four feet 1
