To Preserve Rennet.
Rennet is the lining membrane of one of the stomachs of the calf. Select the stomach of a healthy calf, and empty it. Remove the outer skin and the fat. Wipe the rennet, and then salt it well, using about half a pint of salt, and putting the greater part of it in the sack. Let the rennet lie on a dish for five or six hours, then stretch it on a forked stick. Cover it with netting, to protect it from flies, and hang it up in a cool, dry place. When the rennet is dry (which will be in about a week) put it in a paper bag or a glass jar, and keep it in a cool, dry place. This rennet may be used in making cheese or rennet wine.
