144 Pecan-Growing 



It has been the practice of some walnut-growers of the 

 Pacific slope to put up kernels by the vacuum process, but 

 this was not applied to pecans on a commercial scale until 

 the early part of 1922. There are two types of machines 

 for this work. One of them seals glass jars, while the other 

 seals tin cans. When the kernels are graded, the unbroken 

 and well-formed halves are placed in the glass jars, while 

 the chipped halves and broken pieces are put in tin cans. 

 The machine exhausts the air and seals the top, leaving the 

 kernels in a vacuum. When put up in this manner, the 

 kernels will usually keep indefinitely and can be placed on 

 the pantry shelf of the housewife to be used as needed.
