THE BIRD WHISTLE.
This instrument, also known as the prairie whistle, is clearly shown in our illustration. It is constructed as follows: First, procure a piece of morocco or thin leather. From it cut a circular piece one inch and a quarter in diameter. Through the centre of this disc, cut a round hole, one-third of an inch in diameter. A semi-circular piece of tin is next required. It should be of the shape of an arc, as seen in our illustration; its width across
the ends being about three-quarters of an inch, and its entire length being pierced with a row of fine holes. Next procure a piece of thin sheet India rubber or gold beater's skin. Cut a strip about an inch in length by half an inch in width, and lay one of its long edges directly across the opening in the leather disc. Fold the leather in half (over the rubber), and draw the latter tightly. Next lay on the arc of tin in the position shown in the illustration, and by the aid of a fine needle and thread sew it through the holes, including both leather and rubber in the stitches. When this is done, the whistle is complete. If the gold beater's skin is not attainable, a good substitute may be found in the thin outer membrane of the leaf of a tough onion or leak, the pulp being scraped away.
To use the whistle, place it against the roof of the mouth, tin side up, and with the edge of the rubber towards the front. When once wet, it will adhere to the roof of the mouth, and by skilful blowing, it can be made to send forth a most surprising variety of sounds. The quack of the duck and the song of the thrush may be made to follow each other in a single breath, and the squeal of a pig or the neigh of a horse are equally within its scope. In short, there is scarcely any animal, whether bird or quadruped, the cry of which may not be easily imitated by a skilful use of the prairie whistle, or, indeed, as it might with propriety be called, the "menagerie whistle."
