BLACKBERRIES IN BEARING. 
All previous charts have shown the labor on 10 acres of each 
crop, but this is not possible in the case of the very intensive crops 
unless the scale is changed greatly. For this reason 1-acre charts 
of the intensive crops were made using the scale of 5, 10, 15, etc.

Man labor, except contract work, 5 days. 
If root cuttings are planted it is the third year before a full crop 
of blackberries is obtained. The peak load of work comes in June 
and July, when the crop is harvested, and it is not customary to 
do any work after that time until the old canes are taken out the 
following February. (Fig. 45.) They are then rotten enough to 
break on. They are thrown on the ground between the rows and 
cut to pieces with a disk harrow. The Early Harvest and the Snyder 
are the two varieties most grown.
