Moreover, I point out that a great deal of the most impressive evidence does not depend upon Craig alone. The five drawings with her brother-in-law, Figures 1, 16, 17, 18, 19, constitute by themselves evidence of telepathy sufficient to convince any mind which is open to conviction. While it would have been possible for Craig and Bob to hoax Dollie and me, it could certainly not have been done without Bob’s connivance. If you suggest that my wife and my brother-in-law may have been fooling me, I reply that there is a still greater mass of evidence which could not have been a hoax without my connivance. When I go into my study alone—a little sun-parlor at the front of a beach-house, with nothing but a couch, a chair and a table—I certainly know that I am alone; and when I make a drawing and hold it before my eyes for five or ten minutes, I certainly know whether any other person is seeing it. This covers the drawings presented as Figures 2, 20, and 21, with four others told about in the same series. It seems to me these seven cases by themselves are evidence of telepathy sufficient to convince any open mind. Furthermore, there are the several score drawings which I made in my study and sealed up in envelopes, taking them to my wife and watching her lay them one by one upon her body and write down more or less accurately what was in them. I certainly know whether I was alone when I made the drawings, and whether I made the contents of the envelopes invisible, and whether my wife had any opportunity to open the envelopes before she made her drawings. Of course, I understand the familiar conjuring trick whereby you open one envelope, and hide it in your palm, and pretend to be describing the next one while really describing the one you have seen. But I would stake my life upon the certainty that my wife knows no sleight-of-hand, and anyhow, I made certain that she did not open the first one; I sat and watched her, and after each test she handed me the envelopes and drawings, one by one—the envelopes having previously been numbered by me. She would turn out the reading-light which was immediately over her head, but there was plenty of light from other parts of the room, enough so that I could look at drawings as they were shown to me. Often these tests were done in the daytime, and then all we did was to pull down the window-shades back of the couch.
