Dress, clean, and cut up a four-pound fowl. Put in a stewpan with two slices onion, cover with boiling water, and cook slowly until meat falls from bones. When half cooked, add one-half tablespoon salt. Remove chicken; reduce stock to three-fourths cup, strain, and skim off fat. Decorate bottom of a mould with parsley and slices of hardboiled eggs. Pack in meat freed from skin and bone and sprinkled with salt and pepper. Pour on stock and place mould under heavy weight. Keep in a cold place until firm. In summer it is necessary to add one teaspoon dissolved granulated gelatine to stock.
