SUMMER APPLES IX THE MIDDLE ATLANTIC STATES. 



The following data regarding the occurrence of spring frosts at 

 various points in this region are of particular value when considered 

 with the blossoming dates that constitute a part of the phenological 

 data given on later pages. These data have been furnished by the 

 United States Weather Bureau.

THE SUMMER-APPLE INDUSTRY OF THIS REGION. 



DEVELOPMENT. 



In the sections of this region where there now exist large summer- 

 apple interests, there were formerly very extensive peach orchards. 

 The summer-apple industry, as a commercial feature, has been devel- 

 oped largely since the destruction of many of the peach orchards by 

 yellows. In fact, apple culture has to some extent taken the place 

 of peach growing, many apple orchards now occupying land formerly 

 devoted to peaches. 



Some of the United States census figures relating to the peach 

 interests of Delaware and Xew Jersey are of interest in this connec- 

 tion. Unfortunately these figures are not given in sufficient detail 

 prior to the census for 1890 to admit of any comparison, but those 

 for the year named and for 1900 stating the number of peach trees 

 of bearing age in the States mentioned show the trend during that 



decade, as follows: 



1890. 1900. 



Delaware 4, 521, 623 2, 441, 650 



Xew Jersey 4, 413, 568 2, 746, 607 



Similar data for Kent County, Del., are also suggestive, since very 

 heavy plantings of peaches formerly existed in this county, and at
