Anthology and bibliography of Niagara Falls . swould have to be so far apart in order to insure their never, byany possibility, coming in contact, that the self-induction losseswould make that method impracticable. The evil effects of self-induction are directly proportional tothe number of alternations of the current in a given time, andconsequently the twenty-five-period current adopted for theNiagara Falls work is highly advantageous from this point ofview. The so-called skin-resistance of an alternating current cir-cuit is, in brief, due to the fact that an alternating current pene-trates only a short distance into the body of the metal of whichthe carrying wire is composed, instead of, as in the case of adirect current, flowing across the whole cross-section of the wirein an even manner. This also is less serious the lower theperiodicity. The form decided on in which to construct the conveying linesis that of a conduit or subway of large proportions. One whichhas been already constructed for a length of half a mile is as 960. < u. U H Industrial Niagara follows: The walls are arched, and the width is greatest at 1894about two thirds of the height. The conductors are carried oninsulated brackets along the sides, spaced at intervals of thirtyfeet. The subway is lined with concrete, and manholes at inter-vals allow of access; besides, there are small pieces of pipe let inat the bottoms of the manhole ducts for the purpose of insertingsuch wires as may from time to time be required to tap the lineconductors. The subway is five and a half feet high and threefeet ten inches wide. A track runs along it, and the lineinspectors will make their trips on an electrically propelled car;heavy wire screens the height of the subway, extending on bothsides of the track, protecting the occupants from any possibledischarge from the main conductors. The Cataract Construction Company expect to be able todeliver power in Buffalo at a cost per horse power, for twenty-four hours a
