Oatmeal Cookies

This recipe makes a very large batch of cookies, but they will keep well for weeks. Mix together four cups of flour (into which you have sifted a teaspoon of soda) and three cups of oatmeal.
Add two cups of powdered sugar and three-quarters of a cup of melted shortening with a teaspoon of salt. Moisten the mass with enough cold water to make a very stiff dough. Roll as thin as possible, cut into round cakes and bake.
