REPORT OF CRANBERRY 

 SIBSTATION FOR 1915. 



By H. J. FRANKLIN. 



This bulletin discusses fully the work carried on at the cranberry 

 substation at East Wareham in 1915. It presents more or less 

 definite conclusions in connection with the following lines of 

 investigation: frost protection, effects of spraying with Bordeaux 

 mixture and of treating the water of a June reflow with copper 

 sulfate for the control of fungous diseases, factors affecting the 

 amount of shrinkage of cranberries in storage and in transporta- 

 tion (with practical suggestions), the effects of resanding, the 

 results of fertilizer experiments, and methods of destroying in- 

 jurious insects. The results of several years' tests of resanding 

 and of the use of commercial fertilizers, as shown by quantities 

 and keeping qualities of the fruit obtained, are summarized. 

 Much new information concerning the insect pests and their 

 parasites is presented, and a new and comprehensive system of 

 cranberry bog management is advanced for the consideration of 

 Massachusetts growers.
