Show Electria electrically lly SIe speaking aUng A large mining company baa has arranged for the introduction odthe of the electric light into its pita pits in place pace ot of allowing each miner to carry his own lamp as was heretofore the custom the light will ba be placed along the roads the lamps being fifteen yards apart an admirable suggestion has been made for the propagation of electrical and other scientific knowledge among classes which have no opportunities of attending schools or colleges where the theoretical part of the science can be learned it is proposed to hare have night schools which will be open to young mentho men who are engaged during the day in practical electrical work and who would be glad to avail themselves of the laboratory instruments and instruction which would be pro elded for them an enterprising little village is if coll as near nimes with its inhabitants it has just been lighted by e electricity the motive power being deli denied ed from a small waterfall with a flo flow w a of f about gallons per second and equal to about 9 horse power this waterfall sets inaction in action adana a dynamo mo capable of supplying a light equal to 1600 candles cand lea the streets are lighted by 25 lamps of 16 candle power reach each besides lighting the village rowe age the same power is employed duri during ng the dabin day in putt putting ingin in motion the pumps for supplying tup plying certain parts bf the village with w water ater the rela relative tivo cost of the storage battery electric railway the horse railway and the cable railway is given by the fourth avenue company of or new york which has bad had its storage battery system in operation for a year yea for every 5 cost of the store age system including cost of ca cars r motive power construction of ro roadway d depreciation and repairs and operating expenses there is a cost of tor for the boree horse railway and 1771 for the cable railway for every 1 I 1 of cost for operating the electric rail way there here is a cost of 1333 for operating the horse railway the coat cost of the overhead system is is still less there are many signs which point to the fact that the improvements which have been made in the conduit system tor for streetcar street car work have raised it very much in popular estimation before long this system will be in actual operation on an existing hor horie horte te road the system appears to be the ideal one to many who object to overhead lines and the first one proved to be a practical success will re reap a p a rich reward A successful closed conduit system would be gladly welcomed in ja many towns and cities which are now waiting tas fox electric traction but ara are not willi willing tig to accent accept the responsibility ies es and incur the 1 inconveniences of overhead lines not long ago an enterprising advertiser hit upon the idea of making an electrical tricycle carry his placards through the streets A more realistic idea is that carried out by a firm of bell makers in a western vester c city ity A miniature set of chimes hael has b been een designed to be attached to an electrical tricycle which will travel around the city in the lower part of the frame on which the chimes are fixed is a keyboard ot of between two and three octaves this is played in exactly the same way as tho the organ or piano keyboard ard and some very beautiful combinations nat 0 ns aro are rendered possible all the thirty bells forming the set which are hung on a rack are rung electrically attached to each of them ia an electromagnet electro magnet and the keys make the circuit from a battery in the base to the electromagnets electro magnets at the bells the london electrical refers to an incident in the history of p pretty retty parisian suburb bougival Bou gival on the of october last list was held in that village the annual commemoration of the d deaths e athe of three inhabitants sacrificed in 1 I Annee terrible victims of heir devotion to their native country one otte of these braves known as father Debey debergue gue was an uneducated person over 70 years old who not being anle to take an aati active partin part in the defence of his invaded invade d country made it bis his business to I 1 interrupt 11 terra pt telegraphic communication between the headquarters of the prussian army at versailles and annd an advanced post at boug Bou gival sival the tra transmission of many an important 49 dispatch s was agreste I 1 by the old mans pruning knife but at last he waa was caught t in the very act of cutting the wires taken before a court martial bo be was wits condemned to death the presiding officer taking into consideration 1 I the he advanced age of the culprit offered 0 red to pardon him if ha he woula would swear never to do it again old r father ther debergue Deber nue proudly ansbe answered red 1 I am ain a frenchman and if I 1 get free awill I 1 will do it again A few minutes later be he was shot along the wall it Is gratifying to the large number of american electricians who have watched with confidence in ita its eventful result the huge ferranti scheme at deptford depthford Dept ford england for supplying current at exceedingly high voltages to know that the operation of the ferranti mains has passed the experimental elage stage thirty miles of mains have been laid down and 0 out u t of 8 hilve joints into only fifteen ba have e bee been n found t to 0 be faulty several of these have been du dua to no electrical trouble but t to 0 tho the carelessness of tho the men in forgetting to remove the cotton waste from the socket end there has been hot one single fault from the inner to the outer conductor and this was doe duo to moisture it will be Inte interesting alike to those who prophesied t that at the joints would offer a considerable resistance si on account ot of imperfect contact an and the absence ot of solder and to those who were content to wait developments to know that while the calculated resistance of the mains was ohms tho the actual measured resistance si is 22 ohms after warming tip up the mains by a huge current no difference could bo be detected in whatever joints were accessible immediately after the test a pressure of volts was put on without disclosing any defect these facts are of the utmost significance not only from the importance of their commer cial bearing but also from the influence they aro are likely to have in future developments in the he transmission sion of currents of high voltage N Y sun |
