They have even copied the standard of volts and the form of cut-out. The fact that they have not duplicated this plant would seem, however, to indicate that they have found some difficulties in operation in which perhaps they have not succeeded in obtaining the results of the Edison Company's experiments. For the past ten years Charles Heisler, of St. Louis, has been with commendable pertinacity endeavoring to develope some practical notion in electric lighting. While the arc light was still young, he advertised with great flourish of trumpets, that he had succeeded perfectly in subdividing the arc unit of 2,000 c. p. so as to get any power which might be required with substantially no loss in economy. Like many other of the booming pretensions in the electric light field, this has never been put in practice, and after some years he was obliged to abandon this particular line of experiment. Latterly the company formed to exploit his inventions (which has recently made extraordinary efforts to unload its patent rights and business) has undertaken to imitate the Edison Municipal. Of course, in order to cover distance, it was necessary to copy us in using a large number of low volt lamps in series. In addition to this, Heisler has proposed to " go us one better " by arranging an automatic control of the current on each individual circuit. The Bernstein 5-ampere lamp, about 15 volts for 25 candles, which is superior to anything which Mr. Heisler has been able to devise, was adopted to fill the gap necessary in order to bring out anything which might be sold as a completed system. There are no two Heisler plants built on ...
