Diseases and pests. Spray early with Bordeaux arse- 
nate-of-lead mixture. Melons are subject to the attacks 
of the same destructive insects and fungous diseases 
as cucumbers and squashes.

Mustard for salad may be grown on any kind of gar- 
den soil. Sow the seeds thickly in drills six inches apart. 
For spring use sow as early as the ground can be worked ; 
freezing does not injure the seeds. A succession may be 
had by sowing every two weeks. Sow in September for 
fall salad or greens. For winter use it may be grown in 
frames or boxes, where the cold can be partially excluded. 
To produce seeds for flavoring pickles and sauces, sow 
in April, in rows one foot apart, and thin out to three 
inches apart in the row when two inches high. 
ONIONS 
Varieties. Onions may be propagated from seeds, from 
bulbs (commonly known as sets), and from top sets 
(small bulbs formed on top of the flower stalk). Potato 
onions and multipliers are compound sets, some of whose 
parts may be planted; they are valuable for spring 
bunching. Perennial onions are hardy onions that may 
remain in the ground from year to year; they never form 
large bulbs. Their special value lies in their providing 
green onions for spring and fall use.
