Hornbill
a peculiar bird of Africa and the Philippine region. There are several species. The bird is distinguished by an enormous bill resembling that of the toucan. The bill is surmounted in turn by a large horn or casque. The manner of growth may be comprehended by considering it a tuft of feathers changed into a horn. Despite its appearance the hornbill is said to be related to the kingfisher. It lives on fruit. The female nests in a tree after the manner of a woodpecker. When the hatching season arrives the male closes up the entrance to the nest with clay, leaving only a small aperture through which he passes in food to his mate. Paradise trogon. Hornbill.

Horse Power
the measure of a steam engine's power, as originally settled by James Watt , being a lifting power equal to 33,000 000 pounds p raised one foot high per minute. Thus an engine is said to be of 100 horse power (h. p.) when it has a lifting capacity equivalent to 3,300,000 000 pounds one foot high per minute. To ascertain the horse power of an engine multiply together the pressure in pounds on a square inch of the piston, the area of the piston in inches, the length of the stroke in feet, and the number of strokes per minute, divide the by friction, result by 33,000, and the quotient, less one-tenth, allowed for loss by will give the horse power. Engines are frequently said to be of so many horse power nominal; the real or indicated horse power, however , often exceeds the nominal by as much as three to one.
