I am going to perform this most curious experiment before the present company, by aid of the massive padlock which I take out of its box.
There never was a more simple padlock. I shall lock it here under your eyes, and yet engage to open it without turning the key.
It is now locked, and any gentleman may test its security. I can even hang it on my wand by the ring to prove it, and in that way my friend by my side can hold it for a moment whilst I make a drawing of it on a sheet of innocent white paper.
Open.
Fig. 60.
Closed.
Fig. 61.
Once more let me show that the fastening holds firm. All are satisfied.
I will now apply the key to the hole in the drawing, and turn it once—twice—and cry:—
“Open, Sesame!”
