MISSOURI BOTANICAL GARDEN BULLETIN 77 
to thoroughly penetrate its contents, will require more time 
—approximately double the time for a two-quart jar and 
four times as long for a gallon jar. 
It is hoped that this brief statement as to the fundamental 
principles involved in the preservation of vegetables, to- 
gether with the simple means of accomplishing the desired 
result, will enable those having surplus products from their 
gardens to make the best possible use of them. While the 
three sterilizations may seem a needless repetition, wide ex- 
perience has demonstrated that it is the only method of in- 
suring perfect keeping, unless an expensive apparatus for 
applying steam under pressure can be resorted to. The extra 
time and labor involved will more than offset the loss which 
is almost certain to occur if less thorough methods are used.
