COLOR OF MELON. 
The background color which shows through the openings between 
the lines of netting was noted. Dark-green melons were not as ripe 
as those having light-green or yellowish backgrounds. That melons 
could not be satisfactorily picked on this basis alone, however, is 
shown by the fact that about one-third of the dark-green melons 
had index values characteristic of mature melons of good quality, 
and more than half of them had indexes above 53. Melons could 
not be rejected merely because the background was dark green. 
COLOR OF STEM BASE. 
The stem near the place of attachment to the melon in some cases 
had a greenish tinge and in others a waxy color, resembling paraffin, 
often with a yellow line marking the boundary between stem and 
fruit.
