Every fall and spring and once at least during the summer the birds should all be turned out of the house and yard, that the inside of the building may be well smoked with sulphur, and then thoroughly whitewashed, to secure the destruction of the vermin and the good health of the occupants. A day should be selected when no hens are sitting, and then some charcoal must be kindled in an old tin or pan kept for the purpose in each compartment, and some bits of sulphur sprinkled over the coals when well burning. This done, shut the doors and windows tightly, and leave the sulphur to burn out, which it will do in a few hours; then throw open the doors and windows and let in the air. After this, every part must be well whitewashed, filling all cracks, holes, or corners with the wash,--particularly the nests or boxes for the laying and sitting hens. Sprinkle a few small bits of charcoal in the nests, when dry, to keep them sweet; fill them with fresh straw, and recall the fowls to their clean home. A box or bin of wood-ashes should be placed in one corner of the roosting apartment, and kept always filled, and free from filth, for poultry to roll in and free themselves from vermin as far as possible. The roost should be made so that the poles can be raised or let down at pleasure. In the winter, have the poles raised as high as may be, as the heat ascends, and the fowls need as warm a place as possible for winter. In summer, lower the roost, that they may sleep where the air circulates freely. If possible, provide a good roomy yard back of the hen-house, where the hens may have ample space to range. Plums do well in such yards, and the hens do much toward destroying the curculio. Old pans or wooden troughs filled with water must be kept in the yard, that the hens may have drink at all times. If you have plenty of skim-milk or buttermilk, they will be grateful for all you can spare, and show their gratitude by the increase of their daily offerings.
