Having procured a lump of fresh chalk, break it into pieces of about the size of a large walnut; then, with some heavy instrument, crush, not pound nor grind, these pieces into a coarse powder; when a sufficient quantity (say one or two pounds) has been thus prepared, either pass it through a sieve, or remove the large pieces, crush them, and return them to the powder; next procure a piece of stout calico, into which place the chalk, and tie it up as a housewife would a pudding. A large vessel of clean water should now be obtained, and the crushed chalk, having been allowed to become saturated with the fluid, the bundle should be kneaded, in the hands only: the contents will soon become a thick pasty mass, the milky water gradually ooze through, and the bulk of the chalk become considerably diminished.
