punkah

At night the introduction of the Indian punka into bed-rooms would be valuable, a thin flannel coverlet being spread over the bed.

Twenty-four pulls a minute of a length of 36 inches give in practice a speed of 168 linear feet to the punka curtain.

There are some very important natural laws which are illustrated in the punka.

You cannot, therefore, alter the natural rate of movement of a punka unless you pull it at both sides.
