Dress, clean, and cut up two fowls or chickens. Put in a stewpan with one-half onion, sprig of parsley, and bit of bay leaf; cover with boiling water, and cook slowly until tender. When chicken is half cooked, add one-half tablespoon salt and one-eighth teaspoon pepper. Remove chicken, strain stock, skim off fat, and then cook until reduced to four cups. Thicken stock with one-third cup flour diluted with enough cold water to pour easily. Place a small cup in centre of baking-dish, arrange around it pieces of chicken, removing some of the larger bones; pour over gravy, and cool. Cover with pie-crust in which several incisions have been made that there may be an outlet for escape of steam and gases. Wet edge of crust and put around a rim, having rim come close to edge. Bake in a moderate oven until crust is well risen and browned. Roll remnants of pastry and cut in diamond-shaped pieces, bake, and serve with pie when reheated. If puff paste is used, it is best to bake top separately.
