Make a little figure of cork, in the shape of a dancing mountebank,
sailor, etc. In this figure place a small hollow cone, made of thin
leaf brass. When this figure is placed upon any jet, such as that of
the fountain recommended to be constructed, it will be suspended on the
top of the water, and perform a great variety of amusing motions. If a
hollow ball of very thin copper, of an inch in diameter, be placed on a
similar jet, it will remain suspended, turning round and spreading the
water all about it.
