Butter, 1/2 cup,
Sugar, 2 cups,
Milk, 2 tablespoons,
Salt, 1/4 teaspoon,
Baking-soda, 1 level teaspoon.
Dissolve the soda in a tablespoon of warm water. Cream the butter with 1 cup of the sugar, and add the egg, beaten, and then gradually beat in the other cup of sugar, and the salt.
Add the baking-powder with the milk, and work in enough rolled-oats to make a stiff dough and knead it well.
Roll the dough out into as thin a sheet as possible, and cut into desired shapes. Lift them carefully, and place them on greased pans, and bake in a moderate oven until thoroughly done, light-brown and crisp.
