and over the inside of all new glass jars with a heavy and dull knife to scrape off any slivers of glass or bursted blisters that may be still clinging to the jars. Those on the tops cut through the rubber and cause leakage. Those in the jars may get into the product. I often find these splinters, particularly on new straight-sided jars.

It matters not what type of jar you use. Use what you have at hand, but if you are buying new jars consider the following things before making your selections: No metal, unless it is enameled or lacquered, should come in contact with the food. The jars should be of smooth, well-finished glass. The color of the jar does not affect the keeping qualities of the food. The top or part of the top that comes in contact with the contents should be all in one piece, so as not to offer a place for the accumulation of organisms and dirt. The jars which have nearly straight sides and a wide mouth or opening are easier to wash and facilitate better, quicker and easier packing of the product.

Wash the jars in soap and water. Rinse in boiling water. Some people temper new jars so they will stand the shock of hot water or hot sirup without breaking. If you wish to take this extra precaution put the jars in a dishpan or kettle of cold water after they have been washed in soapy water; bring the water slowly to a boil and let it boil fifteen minutes. After the jars are ready test the rubber rings. This may seem a useless precaution, but it is a necessary one, for there is no one detail in the business of canning that is more important. Even in the best boxes of rubbers there is occasionally a black sheep, and one black sheep may cause the loss of a jar.

Test each rubber before you use it by pressing it firmly between the thumbs and forefingers, stretching it very slightly. If it seems soft and spongy discard it. All rubbers fit for canning should be firm, elastic, and should endure a stretching pull without breaking. A good rubber ring will return promptly to place without changing the inside diameter.

A great many women are laboring under the wrong impression that color affects the quality of a ring. Some women insist on red, and others on white. Color is given to rings by adding coloring matter during the manufacturing process. The color of the ring is no index to its usefulness in home canning.

Use only fresh, sound strawberries or other berries. There is a little knack about preparing the strawberries that few housewives know. Hull the berries by twisting the berries off the hull, instead of pulling the hull from the berry as most women do. You will have a better-looking berry if you will be careful about this. Place the berries in a strainer and pour cold water over them to cleanse them.


HOW TO ADJUST THE COVERS

Never allow the berries or any fruit to stand in water, as the flavor and color are destroyed by water-soaking. Pack in glass jars, pressing the berries down tightly, but without crushing them. Put the rubber on the jar if you are using a jar requiring a rubber. Pour hot sirup over the berries. Put the top of the jar in place, but only partially tighten it.

If using the screw-top jars, such as the Mason, screw down with the thumb and little finger, not using force but stopping when the cover catches.

If using vacuum-seal jars put the cover on and the spring in place. The spring will give enough to allow the steam to escape.

In using glass-top jars with the patent wire snap, put the cover in place, the wire over the top and leave the clamp up.

The cover on a glass jar must not be tight while the product is cooking, because the air will expand when heated, and if the cover is not loose enough to allow the steam to escape the pressure may blow the rubber out or break the jar.

The product is now ready for the canner.


STERILIZING

If you are using the homemade outfit, such as wash-boiler or garbage pail, all berries and soft fruits are sterilized sixteen minutes; in all commercial hot-water-bath outfits and in condensed steam, sixteen minutes; in the water-seal, twelve minutes; in the steam pressure under five pounds of steam, ten minutes; and in the pressure cooker under ten pounds of steam, five minutes. Do not allow the pressure to run above ten pounds for soft fruits; fifteen pounds makes them mushy.

If you use any type of hot-water-bath outfit be sure the water is boiling when the fruit is lowered into the canner, and keep it boiling vigorously for the entire sixteen minutes. At the end of the sterilizing time, immediately remove the jars from the canner.

In taking canned goods from boiling water care is needed to see that they are protected from drafts. If necessary close the windows and doors while lifting the jars out, as a sudden draft might break them.

Examine rubbers to see that they are in place. Sometimes if a cover is screwed down too tight the pressure of the steam from the inside causes the rubber to bulge out. Simply loosen the cover a thread or two, push the rubber back into place and then tighten.

In case the rubber does not seem to fit well or seems to be a poor rubber it should be replaced by a new one, and the jar returned to the cooker for five minutes.

The jars should be sealed tight—covers screwed down, clamps put in place—immediately after they are removed from the cooker.

Invert the jar to test the joint, then let it cool. If the seal is not perfect correct the fault and return the jar to the cooker for five minutes if hot, ten minutes if the jar is cold.

Do not invert vacuum-seal jars. These should be allowed to cool, and then be tested by removing the spring or clamp and lifting the jars by the cover only. Lift the jar only half an inch, holding it over the table, so that in case the lid does not hold the jar and contents will not be damaged. Or, better still, tap round the edge of the cover with a rule. An imperfect seal will give a hollow sound.

As light injures delicately colored fruits and vegetables, it is wise to store them in dark places, such as cupboards, or basement or attic shelves protected from the light. Black cambric tacked to the top shelf and suspended over the other shelves is a sufficient protection from light. A discarded window shade can be rolled down over the shelves and easily pulled up when you desire to take a jar from the shelves.

Canned goods are best kept at a temperature below seventy degrees Fahrenheit, where that is at all possible.


STEPS IN CANNING SOFT FRUITS AND BERRIES

It might be well to enumerate the steps in berry and soft-fruit canning, or do what we called in our schooldays "review it":

1. Get the canner and all its accessories ready.

2. Test and wash jars and tops and put in water to sterilize.

3. Test rubber rings.

4. Make sirup and put in double boiler to keep hot

5. Prepare the product—hull, seed, stem.

6. Place berries or fruit in strainer or colander.

7. Rinse by pouring cold water over product.

8. Pack from strainer into hot jar.

9. Use big spoon to get a firm pack.

10. Dip rubber in hot water to cleanse it and put it in place on the jar.

11. Pour the hot sirup over the fruit at once.

12. Put top of jar on, but not tight.

13. Ready for canner.

14. Sterilize for the necessary length of time, according to the outfit you are using:

MINUTES
Hot-water-bath outfit 16
Condensed-steam outfit 16
Water-seal outfit 12
Steam pressure, 5 pounds, outfit 10
Pressure cooker, 10 pounds, outfit 5
