 - - ! same medium, ether. We have got so | far as to be able Co say that electricity bears something of the relation to light | that heat does. Electricity will produce
 heat and light. Heat will produce cleo | tricity, and so will light have ma | chine in the other room which if light
 gas under it will produce an electric | light or run telephone. Now these
 things show the relation of heat, light
 and electricity and their common line age in the sun.
 Lately scientific men have gone a
 little further. They have discovered 1 that waves of electricity are prOpagated at the same rate as waves of light. They differ probably only in their length and
 their form. This is a step further into
 the investigation of the subject, for it shows a closer relation between light and electricity than used to be supposed existed Now, should say that if machine could be constructed that would generate electric waves with sufficient frequency, it is more than probable that this machine would emit light without heat. If such machine is ever made, and it may be, it will be a mighty aid in the further investigation of this mys- terious what.
 "Everybody is familiar with the re- mark that electricity is in its infancy and that it is the coming power Every electrician has this statement made to him, and when l hear it now always say: Well, when is it coming? Where is it coming frOmY This brings me right back to the question which you filSt asked me If it is the coming pow CT it is coming from coal, because that is the cheapest form of energy which we now possess. In every gwen pound of coal there is certain amount of energy or power stored there by the sun. Now the best engines are enabled to deliver at the belt only from 6 to 10 per cent. of the energy stored in coal This may seem surprising, but it is the result of accurate tests.
 You wonder what becomes of the rest of this energy, and are of course amazed when say that it is wasted, al- most absolutely wasted. It goes off in the form of heat You feel the heat when you enter the boiler room, and you know that much of it goes up the chim- ney. Now, if we can capture that waste, see how greatly it will cheapen cleo tricity. One hundred pounds of coal will furnish the energy which it takes a ton now to furnish, and that means com fort, luxurieS, pleasures for mankind which seem almost incredible. Then truly electricity will not be the coming power, but the power which has come. When l say power mean the force which transmits the energy stored up in coal.
 1t will do almost every kind of labor which now requires the physical work of men, and do it for trifle. It will heat houses in winter and cool them in summer. It will make genuine cheap transit. And might talk for an hour simply telling the things which this cheap electricity will do which now re- quire the hands and arms and muscles of men to perform.
 Therefore as a commercial question the great problem for electricians is this, How to convert the energy which is in coal directly into the electric current? If this can be done we shall save the enormous wastage and do away with the intermediary steam boiler and en- zine It is inconcevable the untold wealth which will follow the solution of this problem. The imagination of man is not powerful enough to conceive of those stupendous developments for the blessing and comfort of mankind which are ill store for us when the energy which is in coal is converted directly into electricity"
 Mir. Carty seemed himself to be im- pressed by the splendor of the vision of the future which he saw with his minds eye, as he thus discoursed, so that for some moments he suspended his conver- satiOn
 At last the writer ventured to ask him if he believed that this discovery would be made in the near future. He replied that Mir. Edison had been studying the problem for many years, but how near ho had approached to d solution he alone knew. Mir. Carty also said that machines had been constructed which would do it, but they were rude, unsat- isfactory and in practical operation were really more expensive than the p c5enS method of using steam power as t!e intermediary.
 "lhcre are many persons who sup pose" said Alr. CGrty, that the electric force is conveyed exactly as the force of water ia upon water wheel, but this is great mistake. There is no physical transfer of force as is the case when water power is used, There is simply wave cuucnt through wire which con voys energy, but which is not itself probably energy, and one of the most marvellous things about this force is that an electric current of great intcn. sity may be conveyed over wire stead fly for years and the finest microscope
