TAMING THE WILD BLUEBERRY 123 



Conclusion. 



The introduction of the blueberry into agriculture has a much 

 more profound significance than the mere addition of one more 

 agricultural industry to those already in existence. Blueberries 

 thrive best in soils so acid as to be considered worthless for ordinary 

 agricultural purposes. Blueberry culture, therefore, not only 

 promises to add to the general welfare through the utilization of 

 land almost valueless otherwise, but it offers a profitable industry 

 to individual land-owners in districts in which general agricultural 

 conditions are especially hard and unpromising, and it suggests 

 the possibility of the further utilization of such lands by means of 

 other crops adapted to acid conditions.^

 of lime is prohibitory, consult "The Agricultural Utilization of Acid Lands by Meacfs of 

 Acid-Tolerant Crops," United States Department of Agriculture, Bulletin No. 6, 1913.
