"No, my boy, of course you didn't, because I adopted my own especial method, which is instantaneous and undetectable, and which I will teach you if you care to learn it; for I seem to foresee that there may be occasions, by and by, when you get out to South Africa, when you may find the power extremely useful to you, particularly if you should get any medical or surgical work to do. In such a case just hypnotise your patient in the way that I will teach you, then powerfully suggest to him that your treatment is going to cure him--and it will do so. As to when I got you under my influence, it was done while I asked you to lend me your penknife." "By Jove!" exclaimed Dick; "it is marvellous, perfectly marvellous; and if I did not know you to be an absolutely truthful man I do not think I could bring myself to believe it. Now I can understand what you meant when you spoke of the potency of hypnotism for good or for evil, and why, as I understand, you have never yet dared to pass on the secret of your power to anyone else. But I swear to you, Doctor, that, if you will entrust it to me, I will never, under any circumstances whatsoever, use it except for a good purpose, nor will I ever pass on the secret to anyone else except with your express permission. And now that you have given me an idea of its capabilities I simply long to know the secret, for it seems to me that a chap with your powers could come very near to working miracles." "Yes," assented Humphreys quietly, "that is so; indeed, even with my imperfect knowledge--for I have not yet nearly mastered all the possibilities of the science--I have done things that without its aid would have been impossible. And now, if you like, I will initiate you into the secret of my power, which is very simple after all, and which, once known, will enable you to do everything that I can do. First of all, however, I propose to throw you into a cataleptic sleep, in order that, while you are in that condition, I may imbue you with an absolute faith in yourself, without which everything that I can teach you would be practically useless, at least until you had acquired faith in yourself by the somewhat slow and laborious process which I had to pursue. I had to acquire faith in myself and my powers by repeated experiments extending over a period of several months; but you have not time for that, so I must imbue you with it by the process of suggestion while you are in a state of trance. Now, are you ready?" "Yes, quite," answered Dick, with a quick indrawing of the breath; for now that it came to the point he suddenly found that to submit himself unreservedly to the hands of even his friend Humphreys, for the purposes of an experiment that smacked rather strongly of the uncanny, was something of a nerve-trying experience. Humphreys evidently noted his momentary hesitation, for he said:
