 buy fresh meat, provided all left-overs are properly cared for. The soup kettle should receive small pieces of beef (roasted, broiled, or stewed), veal, carcasses of fowl or chicken, chop bones, bones left from lamb roast, and all trimmings and bones, which a careful housewife should see are sent from the market with her order. Avoid the use of smoked or corned meats, or large pieces of raw mutton or lamb surrounded by fat, on account of the strong flavor so disagreeable to many. A small piece of bacon or lean ham is sometimes cooked with vegetables for flavor.

Beef ranks first as regards utility and economy in soup making. It should be cut from the fore or hind shin (which cuts contain marrow-bone), the middle cuts being most desirable. If the lower part of shin is used, the soup, although rich in gelatin, lacks flavor, unless a cheap piece of lean meat is used with it, which frequently is done. It must be remembered that meat, bone, and fat in the right proportions are all necessary; allow two-thirds lean meat, the remaining one-third bone and fat. From the meat the soluble juices, salts, extractives (which give color and flavor), and a small quantity of gelatin are extracted; from the bone, gelatin (which gives the stock when cold a jelly-like consistency) and mineral matter. Gelatin is also obtained from cartilage, skin, tendons, and ligaments. Some of the fat is absorbed; the remainder rises to the top and should be removed.

Soup-stock making is rendered easier by use of proper utensils. Sharp meat knives, hardwood board, two purée strainers having meshes of different size, and a soup digester (a porcelain-lined iron pot, having tight-fitting cover, with valve in the top), or covered granite kettle, are essentials. An iron kettle, which formerly constituted one of the furnishings of a range, may be used if perfectly smooth. A saw, cleaver, and scales, although not necessary, are useful, and lighten labor.

When meat comes from market, remove from paper and put in cool place. When ready to start stock, if scales are at hand, weigh meat and bone to see if correct proportions have been sent. Wipe meat with clean cheesecloth wrung out of cold water. Cut lean meat in one-inch cubes; by so
