IIE host facilities for travel within the Worlcl’s Fair _ gl`()\ll'l<]B were those furnished by the Intramural elevated c\|vcl.rio rnilxvniy, winding around just inside the pnlings, from one ond to the other, very much like a big “C” with a curl at each extremity. The line consisted of close upon 15,000 feet of double track and nearly 2,000 foot of single track. Trains mn ordinarily at 4 minute intervals and usually consisted of the motor car and three tr:1,ile1's, all four carrying passengers. All the cars were open, and all the seats were placed across the car, back to back, entrance being made by low doors which slid open or shut, all at the same time. The heaviest train loads were taken up or discharged with wonderful rapidity. As is well known, G\l!'l'El1t~ Was supplied to the motor cars by third rail. The record of such a road as this is surely of interest to every large city in the coumry, and we are glad to be able to record the fact that the service was from first. to last an enormous success. No fewer than 6,000,000 paying pas- sengers were carried, and there was not a single accident. On Chicago day the total ran up to 125,000 passengers for the single day; anfl there were many other days when the figures reached 70,000 or 80,000. The service was smooth, regu- lar and punctual, and the capacity of the road could easily have been increased had it proved necessary. The iigures of operation are being carefully worked ont, but they will show an economy beyond dispute. After such a. brilliant demonstration, it is impossible for any man to declare that elevated electric roads will not work; and it is high time that such roads were availed of to relieve the conges- tion of passenger traflic that now prevails in every large American city, morning and evening and holi- days all the year around. Moreover, it is high time that steam locomotives on elevated roads within city limits were arbitrarily ruled off the traek. One could always sit in the Intramural cars and enjoy the fresh, free air without any stain to clothing or any soot or smoke fly- ing in one’s face; yet only a few yards away the open cars of the Illinois Central were crowded with passengers approaching or leaving the Fair, who were often harassed beyond onflurancs by tho sulpliurous, sooty clouds from the locomotives. The New York Elevated to-day is simi- larly a nuisance, chiefly, perhaps solely, on account of the smoke, soot, oil, ashes, drippings, etc., that it distributes lavishly all the Way from the Battery to the Baseball grounds ; and there is no longer any reason or any excuse for it. We watched personally the Intramural, day in and clay out for six months together, riding sometimes half a dozen times in a single day, and never once did we see the slightest accident, trouble, confusion, or annoyance to any passenger. The motion of the cars was pleasant, and the motive power gave absolutely no sign of its presence. There were probably details to be improved, and that wil1 be improved when new roads are equipped as they are soon to be ; but the system as a whole is an unqualified success. We could wish, as loyal New Yorkers, that this city or Brooklyn were the Hrst, to adopt the new method, but once again Chicago seems to be ahead, for news comes that the Northwestern Elevated Railroad Company has been formed, with a capital of $15,000,000, to operate such a road from Chicago out Evanston way. The directorate includes Mr. Frederick Sargent, recently the electrical and mechanical engineer of the Fair, and we understand that he will have a large share in the work of construction. Is Now York never to have any of these modern conveniences and blessings that Chicago and Liverpool find within such easy reach ? THE TESLA ELECTRICAL OSCILLATOR. ON another page we give a brief description of one form of Mr. Tesla’s mechanico-electric oscillator, which formed part of his exhibit in Chicago. It would be hardly possible at this moment to foresee the ultimate effect which this latest work of Mr. Tesla will have upon the practical de- velopment of the electrical industry. Mr. Tesla is very san- guine, and if only part of his hopes are realized, its import- ance will not be long in making itself felt. The produc- tion of electrical currents in general with simpler apparatus than heretofore employed, and to all appearances with a more economical one, is certainly an achievement to be hailed by all who have the welfare of the industry at heart; while the maintenance of oscillations of constant period which may now be obtained by Mr. Tcsla’s appa- ratus in a positive manner, without the objectionable, older methods, is a result which scientific men certainly cannot fail to appreciate. We are now on the eve of wit~ nessing the carrying out of some of Mr. Tesla/s ideas on a grand scale in the work at Niagara-ideas advanced more than five years ago-and we have cause to feel certain that practical results will shortly some of this latest work. We are thus strengthened in our conviction, long since ex- pressed, that practical results will also follow in the line of economical light production, now that Mr. Tesla has pro. vided more perfect apparatus for the investigation of the phenomena which are associated with his name.
