Tomato Soup

One quart can of tomato, two heaping table-spoonfuls
of flour, one of butter, one teaspoonful of salt, one of sugar, a pint of hot water. Let tomato and water come to a boil. Rub flour, butter and a table-spoonful of tomato together. Stir into boiling mixture, add seasoning, boil all together fifteen minutes, rub through a sieve, and serve with toasted bread. This bread should first be cut in thin slices; should be buttered, cut into little squares, placed in a pan, buttered side up, and browned in a quick oven.
