*The leaves of the beets on the check plots showed the usual signs of 
ripening, but those of the beets on the plots treated with nitrate did not. The 
check plots did not show this change until after the first of October. The 
leaves were frozen about 20 Oct., so these were the last samples of leaves taken 
for the season. The samples of beets taken on this date were analyzed so that 
we could have complete analyese of these samples of which the leaves and 
beets were both in perfect condition.
