"Working thus entirely in the dark, with an intangible, imponderable, invisible something whose nature and attributes are all unknown, and whose characteristics differ essentially from those of any other known force, what wonder if the inventor's progress is slow and his disappointments many? Mr. Keely may be deceived, or he may have discovered an actual force which he is unable to harness; but the fact that he is very slow in perfecting whatever discovery he may have made is no proof that he has not made a very great one. "Far be it from us to say in this age of scientific marvels, that any proposition whatever is impossible of accomplishment; but while we wait for Mr. Keely to make his alleged discovery public, before we become enthusiastic over it, we would not set it down as a fraud and the reputed discovery as a humbug. It is the nature of inventors to be enthusiastic and to think that they are on the eve of success when, in fact, a great deal remains to be done. "Especially is this the case in the development of a hitherto unknown force. James Watt had a comparatively straight road to travel from his mother's tea-kettle to his first steam-engine, but it took him many years to traverse it. More than a lifetime elapsed after Franklin drew electricity from a cloud before Morse sent it over a telegraph wire, and Morse himself worked for years to make it available for business purposes; while men are still constantly finding new adaptations of the mysterious force of which that was the first practical application."
