"May 20th.--Yesterday was a day of trials and disappointments. It seemed as if nothing would work right. After labouring six hours to set my safety process, the first operation of the Liberator tore the caps all to pieces. I replaced them by a set of duplicates, and set the Liberator down to the low octaves, when everything worked to a charm. Night was approaching, and I left the workshop to get something to eat, returning about eight o'clock to re-conduct experiments, in order to discover if possible the cause of the sudden and most unexpected intensification. I followed up with great care the progressive lines until I reached the tenth octave, and then liberated a score of times, yet no variation on liberator. Next, I made an attachment to my safety arrangement, and also to my strongest resonator, to experiment on vibratory rotation with my shell; when, within two minutes, it attained a frightful velocity: then I suddenly retracted to the negative, bringing the velocity down from about 1500 per minute to 150. The operation was magnificent, lasting sixty-four minutes, when a second intensification took place, demolishing two safety-shells and one vibratory indicator. I was perfectly dumbfounded, and unable to account for such a phenomenon. It was then near midnight, but I had made up my mind not to discontinue until I had solved the mystery. After an hour's reflection, I set up a new position on the resonating wave plates in the forty resonating circuit on the base of liberator; and got a result which for purity of uniformity surpassed all experiments that I have ever made. I believe I have now struck the root of this difficulty, and that I shall be able to master it; and obtain continuity of action with perfect rotation." "June 1st, 1885.--I am in a perfect sea of mental and physical strain, intensified in anticipation of the near approach of final and complete success, and bombarded from all points of the compass by demands and inquiries; yet, in my researches, months pass as minutes. The immense mental and physical strain of the past few weeks, the struggles and disappointments have almost broken me up. Until the reaction took place, which followed my success, I could never have conceived the possibility of my becoming so reduced in strength as I am now. My labours in the future will be of a much milder character; but, before I again commence them, I must have a few days more of recuperation. I was so absorbed in my researches that I forgot my duty to myself, as regards the requirements of health, and I am now paying the penalty. It has been misery to me to have absorbed so much more time and capital than I anticipated; and without the heaven-sent aid which I have received the world would have lost sight of me for ever."...
