NEWEST WIND MACHINE
]
Stage wind is produced by means of a large drum or wheel made of slats
of wood, with about three inches of space between the slats. This drum
is fastened to two uprights and has a large handle attached to the
centre, so that it can be turned round and round very easily. Above the
drum is fixed a stout rod, from which hangs a large piece of moiré silk.
This silk hangs over the drum, and when the drum is turned the sound
made by the slats of wood touching the silk produces the sound of wind.
The illustrations show how the appliance can be made.
