After the cans have cooled, and the tops have been screwed down tightly, place them in a cool place, bottom upward, and watch closely for a few days. If the juice begins to leak out, or any appearance of fermentation is seen, it is a sign that the work has failed, and the only thing to do is to open the can immediately, boil the fruit, and use as quickly as possible; recanning will not save it unless boiled a long time. If no signs of spoiling are observed within two or three weeks, the fruit may be safely stored away in a dark, cool place. If one has no dark storeroom, it is an advantage to wrap each can in brown paper, to keep out the light. Sometimes the fruit will settle so that a little space appears at the top. If you are perfectly sure that the can is tight, do not open to refill, as you will be unable to make it quite as tight again, unless you reheat the fruit, in which case you would be liable to have the same thing occur again. Air is dangerous because it is likely to contain germs, though in itself harmless. If mold is observed upon the top of a can, it should be opened, and the fruit boiled and used at once, after carefully skimming out all the moldy portions. If there is evidence of fermentation, the fruit should be thrown away, as it contains alcohol. If care be taken to provide good cans, thoroughly sterilized, and with perfectly fitting covers; to use only fruit in good condition; to have it thoroughly cooked, and at boiling temperature when put into the can; to have the cans well baked and heated, filled completely and to overflowing, and sealed at once while the fruit is still near boiling temperature, there will be little likelihood of failure. OPENING CANNED FRUIT.--Canned fruit is best opened a short time before needed, that is may be will aërated; and if it has been canned without sugar, it should have the necessary quantity added, so that it may be well dissolved before using. Fruit purchased in tin cans should be selected with the utmost care, since unscrupulous dealers sometimes use cans which render the fruit wholly--unfit for food. The following rules which we quote from a popular scientific journal should be 'carefully observed in selecting canned fruit:-- "Reject every can that does not have the name of the manufacturer or firm upon it, as well as the name of the company and the town where manufactured. All 'Standards' have this. When the wholesale dealer is ashamed to have his name on the goods, be shy of him. "Reject every article of canned goods which does not show the line of resin around the edge of the solder of the cap, the same as is seen on the seam at the side of the can. "Press up the bottom of the can; if decomposition is beginning, the tin will rattle the same as the bottom of your sewing-machine oil can does. If the goods are sound, it will be solid, and there will be no rattle to the tin.
