15. Marketing bunching onions. — Before pulling any of the 

 bunching onions it is important to visit the markets to be supplied 

 and learn what is the usual method of marketing. First, note 

 the number of onions in each bunch and also the size of the onions ; 

 second, whether they are clean and neatly bunched ; third, the 

 kind of tying material used. Then study how you can improve 

 on the methods you have observed. It is especially important 

 to see that the bunches are neat and clean, and tied with strings 

 or tape that enhance rather than mar the appearance of the 

 bunches.

16. Harvesting mature bulbs. — Sometimes the market is so 

 good for onions that we are justified in harvesting them before 

 they are fully mature. Ordinarily, the bulbs should not be har- 

 vested until they are fully ripe, as indicated by the dead and 

 shriveled tops. Dry, sunny weather is most favorable for this 

 operation. Several rows of onions are pulled and thrown together 

 into a windrow. They are left undisturbed for a few days and 

 then stirred occasionally with a wooden rake to facilitate drying. 

 The tops should be removed with shears or knife, leaving about 

 an inch of the neck. If ample space is available in a shed or loft, 

 so that the bulbs can be spread in layers only a few inches deep, 

 they need not dry so long in the field.
