eluding Wisconsin, Iowa, Minnesota, the Dakotas, 

 Manitoba and neighboring areas. They also do well 

 in Quebec, Ontario, Vermont and the northeast gen- 

 erally, though they do not seem to thrive with quite 

 the same fervor as in the region just described. Per- 

 haps this is because less attention has been given 

 to them. 



The Wildgoose varieties are favorites in many 

 central and south-central parts of the continent. The 

 Chicasaws are commercially profitable in some of 

 the southern states. Varieties of the Wayland class 

 are less well known, but are especially adapted to cer- 

 tain parts of Texas, Alabama and other southern 

 states. They have been favorably reported from Mary- 

 land and Missouri. 



In general it seems safe to say that each locality 

 will be best served by some few varieties, and that 

 these will succeed much better than others. The 

 problems of variety adaptation in plum culture are 

 more intricate and appear to be more local than with 

 any other group of fruits. This means, in practical 

 application, that the plum amateur must be more of an 

 experimentalist than the ordinary horticulturist; and 

 also that the beginner must pay more close attention 

 to the varieties which have proved successful in his 

 own locality and give little heed to reports of success 

 or failure in other parts of the country. 



PHENOLOGY 



Some of the most curious and valuable points 

 connected with the relationship of fruit trees to their 

 climatic environment are those connected with the 

 seasons of blossoming, leafing and ripening. The im- 

 portance of a careful study of blossoming seasons is 

 explained in the chapter on pollination; and season
