Keely has found no "resting-point" in his researches of a lifetime; and, instead of being "welcomed with confidence" by his fellow-researchers in science, he has suffered at their hands more than will ever be known by his detractors. Keely's discoveries would have died with him, through the calumnies of these same scientists, as far as demonstration was concerned, had not a company been formed, in the early days of his inventions, which for many years furnished him with the necessary funds, expecting almost immediate financial success. The sneers of men of science crying "Charlatan," the ridicule of the public press, and the denunciations of the ignorant have been mighty factors in debasing the value of the shares of the company. The courage, faith, and contributing capacity of nearly all the stockholders have given out; and it is fortunate that now Mr. Keely's work of evolution has at last reached the point where he is able to convince those scientists of his integrity whose minds are broad enough to conform to what Herbert Spencer has said is the first condition of success in scientific research,--viz. "an honest receptivity, and willingness to abandon all preconceived notions, however cherished, if they be found to contradict the truth." Keely may be said to have spent years of his valuable time in giving exhibitions whereby to raise the funds needed for his scientific researches. Again and again has he taken apart his various machines, to show their interior construction to the sceptical; and what this means, in the attendant delay, will be better understood when he has made known how slight a thing, by the laws of sympathetic association, may retard his progress for days, even for weeks. Take, for example, his last experience with his preliminary commercial engine, to which, before he had completed his graduation, he was induced, in November 1889, to apply a brake, to show what resistance the vibratory current could bear under powerful friction. A force sufficient to stop a train of cars, it was estimated, did not interfere with its running; but under additional strain a "thud" was heard, and the shaft of the engine was twisted.
