"When the history of his discoveries and inventions come to be written there will be no more pathetic story in the annals of genius than that of John Worrell Keely. The world hereafter will find it hard to believe that in the last quarter of the 19th century a man with an insight into the secret workings of nature, and a knowledge of her subtler forces, which, whenever it is utilized, will relieve mankind from much of the grinding toil that now makes bitter the existence of the vast majority, that such a man should have been left unaided, because in all the ranks of science there was not found one man capable of understanding his colossal work--because in all the ranks of religion there was not found one man able to realize the enlarged conception of Deity immanent in Keely's great thoughts--because in all the ranks of commerce, of speculation, of literature, of art, there was not found one man large enough, generous enough, unselfish enough, to furnish money for a purpose that did not promise an immediate dividend." Again in 1888, more than ever was Keely held up to ridicule by all those men who possess the instinct of the brute to hound down its prey, and his supporters came in for their share of abuse. Among this class, or of it, were men so ignorant of Keely's claims, and of the object of his researches, that they represented him as "a seeker of the impossible," a "perpetual motion crank," throwing upon his character other odium which the speculating managers of "The Keely Motor Company" were justly responsible for. One of these communications alone is enough to show the quality of the weapons used against him. It appeared in The New York Daily Tribune. THE KEELY MOTOR CRAZE. A Donkey-Cabbage Race. HOW MUCH LONGER WILL THE CLEVER JUGGLER BE ABLE TO DELUDE HIS VICTIMS? To the Editor of "The Tribune." Sir,--The success with which Keely has deluded his victims by appealing to their credulity with a mystery, and to their cupidity with a promise of "all the kingdoms of the earth," which would not be of greater value than the monopoly of infinite power without cost, which he dangles before their astonished vision, makes him and his antics subjects of unusual interest. His last performance appears to be an issue of 5,000,000 dols. of new stock representing a new discovery veiled in mystery, which is to far outstrip his former one, on which 5,000,000 dols. of stock was issued and is now held by his dupes. Two of these new millions are to go to the old holders as a compensation to them for their disappointment in not realizing perpetual motion under the old discovery; two more to go to Keely to be sold to the public; and the remaining one million is in the treasury to be sold for the benefit of Keely and the others, half and half.
