accompanied by his assistant. He has a sack
similar to a meal bag only on a large scale. The upper end of this
bag is shown in Fig. 1, with the rope laced in the cloth. He then
selects several people from the audience as a committee to examine
the sack to see that there is absolutely no deception whatever in
its makeup. When they are satisfied that the bag or sack is all
right, the magician places his assistant inside and drawing the
bag around him he allows the committee to tie him up with as many
knots as they choose to make, as shown in Fig. 2.

The bag with its occupant is placed in a small cabinet which the
committee surround to see that there is no outside help. The
magician then takes his watch and shows the audience that in less
than 30 seconds his assistant will emerge from the cabinet with
the sack in his hand. This he does, the sack is again examined and
found to be the same as when it was first seen.

The solution is when the assistant enters the bag he pulls in
about 15 in. of the rope and holds it, as shown in Fig. 3, while
the committee is tying him up. As soon as he is in the cabinet he
merely lets out the slack thus making enough room for his body to
pass through. When he is out of the bag he quickly unties the
knots and then steps from his cabinet.

** The Invisible Light [251]

The magician places two common wax candles on a table, one of them
burning brightly, the other without a light. Members of the
audience are allowed to inspect both the table and the candles.

The magician walks over to the burning candle, shades the light
for a few seconds, turns to the audience with his hands a few
inches apart, showing that there is nothing between them, at the
same time saying that he has a light between his hands, invisible
to them (the audience), with which he is going to light the other
candle. He then walks over to the other candle, and, in plain
sight of the audience lights the candle apparently with nothing.

In reality the magician has a very fine wire in his hand which he
is heating while he bends over the lighted candle, and the
audience gaze on and see nothing. He turns to the other candle and
touches a grain of phosphorus that has been previously concealed
in the wick with the heated wire, thus causing it to light.
