_Canning and preserving._--Other methods of preservation are desirable, in order that vegetables and fruits be made of value for a longer period of time than through their ripening season. Canning is one of the methods most commonly employed in the home, being both easy and satisfactory. Fruit which is to be canned is first sterilized by boiling or steaming, in order to destroy all germs and spores. This can be adequately accomplished by boiling for twenty minutes, but a shorter time is sometimes sufficient. In order to ensure complete success, all germs must also be destroyed on the cans and on everything which comes in contact with the food. This will be effected by boiling or steaming for twenty minutes. The jars, covers, dipper, and funnel should all be placed in cold water, heated until the water comes to the boiling-point, boiled five minutes, and left in the water until just before sealing. As for the rubbers, it will be sufficient to dip them into the boiling water. After the fruit has been put into the can, it must be sealed so that it is perfectly air-tight. In order to do this, it is necessary to have good covers, with new, pliable rubbers, and to see to it that they fit tightly. When the jar is to be filled, it should be placed on a board or wooden table, or on a cloth wrung out of hot water, and should be filled to overflowing. Sugar is not essential to sterilization and is used only to improve the flavour. Both fruits and vegetables can be canned without sugar. However, fruits canned with a large amount of sugar do not spoil readily, for germs develop slowly in a thick syrup. _Methods of canning._--The simplest method of canning is the "Open-kettle Method" employed for small, watery fruits, such as berries, grapes, tomatoes, etc. The fruit is boiled in an open kettle (which permits of the evaporation of some of the water in the fruit) and transferred at once to a sterilized jar, which is immediately sealed. Another and safer method, which secures more complete sterilization without serious change of flavour in the fruit, is that known as the "Cold-pack Method". After being transferred to the cans, the vegetable or fruit is subjected to an additional period of heating of considerable length, or to three periods of briefer length on three successive days. If the three periods of sterilization are used, the process is known as the "Intermittent Method". The Single Process Method is described in the recipe for canned beets. The Intermittent Process proves more satisfactory for canned beans. PRELIMINARY PLAN The teacher should ascertain what fruits and vegetables are most abundant and select for canning those that the class can provide. Each pupil should be asked to bring some vegetable or fruit, some granulated sugar, and a jar in which to can her fruit. If the school does not possess enough kettles or sauce-pans in which to do the cooking, they may be borrowed from the homes.
