The method employed in changing say a white handkerchief for a red one being explained, the other uses of the tube will be apparent. Load a red handkerchief into the cup at the end A, and place it under your vest, or in the righthand trousers pocket. Give the tube and caps for examination, and while they are out of your hands, get possession of the cup and palm it in your right hand. Take back the tube with the left hand, pass it into the right, and over the cup; and fit the cap to the opposite end. Turn over the tube, and with the right hand apparently place the white handkerchief into it (the handkerchief really goes into the cup and pushes the red one into the tube, reversing the tape). Now place the right hand over the cup, reverse the tube, and remark:—"As the cap has been on this end the whole of the time, it has not been possible for the handkerchief to escape in that direction. We will now place a cap on the opposite end of the tube and we have the handkerchief secure." Saying this, reverse the tube, palming off the cup while doing so; and while holding the tube in the same hand, to hide the palm, fit on the cap. Give the tube to some one to hold and drop the cup into the profonde, or otherwise dispose of it at the earliest opportunity.
