LIMA BEANS. 



The variety of Lima beans used in these tests was the Dwarf Garden 

 King. The beans were full grown but not dry and were in prime 

 condition for table use. They were gathered, brought into the labor- 

 atory, and shelled by hand. The shelled beans were washed and 

 packed tightly into the cans without being blanched, and only enough
