Between slices of brown or white bread and butter place thin scollops of cooked fish of any kind you may happen to have most handy; spread a little Tartar sauce over the pieces of fish, and strew some shred lettuce-leaves over all; press the other slice of bread and butter upon this ; cut up the sandwiches in squares; dish up, and serve.
Note.—Thin slices of hard-boiled eggs, or sliced Indian or common gherkins may also be added to the other ingredients.
