INSTRUMENT TO IMITATE THE VOICES OF ANIMALS.

Make a very long dram, covered at one end only with sheep or ass skin. On this head is fastened a length of catgut, attached at its centre to another such catgut cord which runs through the drum to the other end.

Action.—The drum is held between the knees, while the operator, wearing a glove soaked in colophony, rubs the catgut more or less briskly ; whence result growls, groans, and other sounds imitating the roars of wild animals, long or short as one pleases.
