Coltsfoot Rock.
Instead of two quarts of gum mucilage use one, and about a quarter pound gum dragon well soaked in a quart of water; this must be done twenty-four hours before it is required, force it through a coarse cloth or sieve; mix the liquorice in with half an ounce of essence of lemon; the paste must be stiff and tough to pass through the machine or it will not look smooth.
