278 EL ECTRIC LIGHTING. 



of the Pont Notre-Dame, where it was brought into use for 

 the first time, it has always been employed whenever any 

 important work had to be expeditiously performed. It has, 

 for instance, been made use of in the works for the Docks 

 Napoleon, in the rebuilding of the Louvre, &c., &c. In such 

 applications the lantern is commonly set up at the top of a 

 wooden post, and is furnished with a reflector for throwing 

 the light downwards. It has also been proposed to apply 

 the electric light in field labours in order to expedite harvest 

 operations. Albaret, the head of a great firm of agricultural 

 implement manufacturers at Liancourt, has lately made at 

 Mornant and at Petit-Bourg, experiments that have proved 

 successful. The apparatus (described in the journal L'&lec- 

 tricite of the 5th Sept., 1878) is composed of (r) a portable 

 steam-engine ; (2) a dynamo-electric machine of some kind 

 or other ; (3) a post made of iron bars, serving to carry the 

 lantern and the lamp, and fitted to the portable engine. 

 The engine may, if it has sufficient power, be utilized to drive 

 a thrashing machine. A windlass in front of the chimney 

 enables the post to be raised or lowered. 



Application to Lighting Railway Stations, Work- 

 shops, &c. The electric lighting of large workshops and 

 railway stations is now un fait accompli. Following Her- 

 mann-Lachapelle, who was one of the first to enter upon this 

 course, a multitude of other manufacturers now use it with 

 very great satisfaction. Fontaine's book tells us that Gramme 

 machines now illuminate the establishments of Ducommun, 

 at Mulhouse; of Sautter and Lemonnier, at Paris ; ofMenier, 

 at Crenelle, Noisiel, and Roye; the spinning-mills of Dieu- 

 Obry, at Daours; of Ricard fits, at Mauresa (Spain); of 

 Buxeda, at Sabadell (Spain) ; of David, Trouillet, and Ad- 

 hemar, at Epinal ; of Bourcard (Doubs) ; of Horrocks and 

 Miller, at Preston; the weaving-shops of Gr^goire, at Creve- 

 Coeur-le-Grand ; of Manchon, at Rouen; of Brindle, at Pres- 

 ton; of Mottet and Baillard, at Rouen: of Isaac Holden,
