BLUEBERRY CUTTINGS IN EARLY STAGES OF GROWTH. 
The figure at the left shows a cutting callused at the base and the uppermost bud pushing, 
but the green bracts and young leaves not yet expanded. In the middle and right-hand 
figures callusing has proceeded farther at the cut surfaces, both top and bottom, and the 
formation of new leafy twigs is well under way; but the growth of the tips has not yet been 
terminated. As shown in the right-hand figure, twigs are often produced from two of the 
upper buds, sometimes more. (Natural size.)
