The operation of canning is simple, yet it requires an 

 expert to do the work well, so that when it is done 

 the material will not degenerate in the cans. The prin- 

 ciple involved is simply to place the material to be canned 

 under a temperature sufficient to kill all living organisms 

 contained therein, and in this condition it is sealed. Under 

 these circumstances there can be no degenerating, no 

 fermenting, and no rotting.

Damping-off may occur in the seed-beds, the seedlings 

 being cut off near the ground. It does not usually happen

Root-knot often starts from the young plants in the 

 seed-beds. It may be combated by careful choice of 

 seed-beds, by sowing the seeds in the open field, and by 

 rotation. 



Cutworms, which attack the young plants, are best 

 destroyed by poisoned bait. 



Rust begins as brown spots, which spread over the leaves. 

 It can be prevented by spraying the plants in the seed-bed 

 with bordeaux mixture ; and when found in the field, 

 several sprayings will save the crop.
