OrB COAL AND OUE COAL PORTS. 113 



Primarily he applies a part of this enormous power by using 

 300-horse power of the whole to the working of four of Grirard's 

 double force pumps, to drive water up 525 feet to a reservoir 

 made on the highest land, at Parolles, near the town, at a dis- 

 tance of about a mile and a half, transmitting each minute, by 

 pipes of 15-inch diameter, 690 gallons of crystal water, for drink- 

 ing purposes only, and which water is all filtered at the water- 

 works by the dam, prior to its entering the main. 



The filter works alone cost 34,600 francs, £1,380. 



Her E,itter, as Engineer and Director of his Company, farms out 

 the rest, or as yet only a part of the rest, of this great water 

 power, to various manufactories which have been recently erected 

 around these works. This he does by means of the new and so- 

 called telodynamic action, transmitted to long distances, uj) to 

 half an English mile, by endless wire ropes carried through tun- 

 nels and along valleys in various directions by ingenious con- 

 trivances, and over stone pillars capped with rollers to keep the 

 traction straight — one of which pillars is 60 feet high. 



Eor this he obtains a rent equal to 150 to 200 francs per 

 annum for each horse-power, according to quantity used — thus, 

 if we include the 300-horse power for pumping the drinking 

 water for the town, at same rate of rent as the rest, it will be 

 found that he can obtain an annual rent on the whole 4,000- 

 horse power available, and at only the minimum price of 150 

 francs for each horse-power, equal to 600,000 francs, or £24,000. 

 But let us now reduce the returns by one-half, or as upon only 

 2,000-horse power used, and he would still have £12,000, which 

 would be equal to 15 per cent, on the total subscribed capital of 

 two million francs, or £80,000 for the entire undertaking. 



The Company afterwards extended their capital, and purchased 

 1,400 English acres of forest in the immediate neighbourhood, for 

 the sum of 1,400,000 francs, such purchase being made from the 

 town of Ereibourg with the consent of the State. 



The Company is therefore now called the " Societe Generale 

 des Eaux et Eorets," and it retains for its own use no less than 

 than 300-horse power for theefiective working of their own large 

 sawmills, with twelve saws and other machines. This power is 

 transmitted to a distance of half a mile by means of the telody- 

 namic cable. 



The rest of the motory power is all farmed off* to the numerous 

 manufactories started, and which are already seven in number, 

 one of which alone demands from 50 to 150 horse power, -and is 

 applied to an immense railway-carriage manufactory that sends- 

 its carriages to all parts of the Continent. 



This establishment also absorbs one-seventh part of all the 

 timber sawn by the parent Company.
