26 GARDEN PROJECT 
expiration of this time, the jars are removed and the 
lids tightened. If it is found that a rubber has been 
blown out of place it should not be pushed back but 
removed and a new one substituted. The jar should 
then be put back in the canner and sterilized for an- 
other five minute period. 
Corn on the cob may be canned by the same method 
by using wide mouthed jars. This is not an economical 
method of food preservation, however. All jars and 
tops should be carefully inspected before use. 
Be sure that Mason jar tops are smooth and touch 
the rubber at all points. This may be determined by 
screwing down the lid, without the rubber, and trying 
to insert the thumb nail at different points. Be sure, 
too, that the wire bale of glass topped jars comes into 
place in the slot with a click. Defect may be remedied 
by bending the wire in. 
(b) Peaches. The canning of peaches differs from 
that of corn in three respects: (1) The peaches are 
‘‘hot-dipped’’ about one-half minute. (2) Syrup* 
instead of water is poured over them. (3) Peaches 
are sterilized in the hot-water canner for sixteen min- 
utes only. 
7. Acanning demonstration. The class should give 
a public canning demonstration. Parents, patrons and 
friends may be invited. It will add greatly to the 
appearance of this demonstration if the members of 
the demonstration team are attired in white aprons 
and caps, bearing the official club insignia. Directions 
for making these are given in a bulletin listed in the 
*If sugar is high, fruit may be put up in water. For directions
