Dominoes - cake recipe

Make a sponge cake batter, and bake in long tins, not too large. The batter should not exceed the depth of one-fourth of an inch, spread it evenly and bake it in a quick oven (line the tins with buttered paper).
As each cake is taken from the oven, turn it upside down on a clean board or paper. Spread with a thin layer of currant or cranberry jelly, and lay the other cake on top of it. With a hot, sharp knife cut into strips like dominoes; push them with the knife about an inch apart, and ice them with ordinary white icing, putting a tablespoonful on each piece, the heat of the cake will soften it, and with little assistance the edges and sides may be smoothly covered. Set the cakes in a warm place, where the frosting will dry. Make a horn of stiff white paper with just a small opening; at the lower end. Put in one spoon of dark chocolate icing and close the horn at the top, and by pressing out the icing from the small opening, draw a line of it across the centre of each cake, and then make dots like those on dominoes. Keep the horn supplied with the icing.
