Dust weekly with sifted ashes, corn starch in powder, and flowers of sulphur. Use in dry weather, putting on at night. Have hutches big enough to prevent crowding. Beware letting your pets overrun the space at command. =Birds=: Mocking-birds, cardinals, bullfinches and orioles, all of which it is wicked to keep in cages, need very roomy cages, perches with the bark on, much clean sandy earth on the floors, clean grain, green stuff, ripe fruit, and insects, besides the egg-and-potato mixture which is their mainstay. Tie heads of wheat, oats, or millet to the bars, hang lettuce and peppergrass there, also chickweed in season. Put ripe berries on clean twigs and suspend; force bits of apple and peach between wires close to the perches. Have a swing, a roomy bath, with the usual feed and water cups. Change the water daily, twice in summer. Put one drop of carbolic acid in the bath for insect prevention. Boil eggs twenty minutes, crush the yolk while hot with a freshly boiled Irish potato, season with the least grain of salt and a very little red pepper, and put into the cup. Keep the cage very clean, scald it every three months. Hang it outside in pleasant weather, but never so the sun at midday will strike full on the birds. Give flies, crickets, earth worms, grasshoppers, but not hairy caterpillars, spiders, nor wasps. Mockers sing almost the night through in spring. To silence them cover the cage with something thick, set where it is very dark, then uncover. =Canaries=: A long body and thick smooth plumage are marks of a good canary. Males only sing. Coat color varies. German canaries show many shades of yellow besides mottled tints. Yellow-red Norwich birds owe their giddy coats to red pepper in the food. Unless it is given liberally at moulting-time their fine feathers come back dull and pale. Birds are in full song at a year old. Younger, they have rarely been well taught. The range of life is seven to twenty years; the last is possible only with exceptional birds and still more exceptional care. Teach canaries to deserve the freedom of the room. It helps in many ways. Leave the cage door open; do not coax him out nor force him in except as a last resort. Rather let hunger take him back. He will learn quickly and enjoy flying about.
