Fish Soup

1 lb. cod, or other white fish
2 tablespoonfuls Crisco
1 quart white stock, or half milk and half water
1 small carrot
1 small onion
1 stalk celery
3 parsley sprigs
1 blade mace
2 egg yolks
1/2 cupful cream
1 lemon
2 tablespoonfuls flour
1 teaspoonful chopped parsley
Dry toast

Wash and dry fish and cut into small pieces. Put into saucepan with stock, vegetables cut in small pieces, parsley and mace. Let these simmer for half hour, then strain off liquid. Melt Crisco in pan, stir in flour, then add fish liquor and stir till it boils. Draw it to the side of fire and let cool slightly. Beat yolks of eggs with cream, and, when soup has cooled, strain them in. Reheat soup without boiling it, to cook eggs. Season, and add few drops lemon juice and chopped parsley. Serve with small pieces of dry toast.
