A Stage of Development 



In the course of his experiments, Mr. Burbank has worked 

 extensively with several species of California strawberries. 

 These show a very wide range of variation, growing in different ter- 

 ritories, and give good opportunity for selection. As might be 

 expected, combinations between these wildlings and the 

 cultivated varieties often show great vigor of growth, 

 and give the plant-developer the oppor- 

 tunity he is seeking.
