In view of these facts the curious question is why the donkey goes on any further. The revolving ball is a fact known to hundreds of the stockholders. It is either a real cabbage capable of feeding the donkey with a perpetual feast, like the widow's cruse of oil, or it is only a sham such as any good mechanic could construct and operate as Keely did. Why doesn't the donkey balk and insist on biting into the cabbage? If it is real the Keely stock is worth untold millions. It would put an end to steam engines and electric batteries for ever. One of those balls in the corner of a room would make all the heat and light which could be used, and have power to sell; and all that would be needed would be to learn Keely's cabalistic signs on the blackboard in order to make it start, and to stop it when it had done enough. But if the ball is only a trick, then, of course, Keely could be sent to prison, and his victims could close their accounts and be sure that they would lose no more by him. Without going any further into the history of this remarkable delusion, which is full of similar tricks too numerous to mention now, it seems clear that these facts ought to be used to bring to an end in one way or the other the Keely craze. Edward N. Dickerson. New York, Nov. 30, 1888. It is difficult to understand how anyone could concoct and put together such a tissue of fabrications as this, when the sole foundation for such a tissue lay in the fact that it was at this juncture that Keely made the announcement that he had proved the uselessness of building engines to employ the ether as a motive power; which could only be used as the medium for the power which he had discovered, namely, a condition of sympathetic vibration, associated both positively and negatively with the polar stream. The statement made of the issue of new stock is absolutely untrue. The revolving globe was never created to be "the source of power," and the representation of the manner in which the globe was made to revolve, and that Keely affirmed he could produce with it "an indefinite amount of horse power without current expense," is denied. The suggestion that Keely could be sent to prison was welcomed by those who eventually acted upon it, with the result that Judge Finletter committed Keely to Moyamensing Prison, for contempt of court, but not for fraud. Mr. Keely, at that time, wrote of those who called him a perpetual motion seeker:--"I console myself by thinking that if they were not ignorant of the grand truths which I am devoting my life to develop into a system, they could never bring forward such an absurd charge. Perpetual motion is against nature, and it is only by following nature's laws that I can ever hope to reach the goal I am aiming to reach." The Supreme Court reversed and set aside the order of the court committing Keely for contempt, and released him from custody, upon the writ of habeas corpus taken out on his behalf, within three days of his commitment.
