Petit's method of making coffee

On one measure of the coffee ground into meal
pour three measures of boiling water.

boil on hot ashes lined with coal till the meal dis-
   appears from the top, when it will be precipitate.

pour it three times through a flannel strainer.

it will yield 2 1/3 measure of clear coffee.

an ounce of coffee meal makes 1 1/2 cup of clear coffee
   in this way.

the flannel must be rinsed out in hot or cold wa-
   ter for every making.
