REPORT OF CRANBERRY 

 SIBSTATION FOR 1914 



By H. J. FRANKLIN 



This bulletin contains a full report on the work at the cranberry sub- 

 station in Wareham for the year 1914. It presents conclusions on many 

 important points, among which some of the more prominent are: frost 

 protection, prevention of fungous diseases, effect of spraying upon the 

 keeping qualities of the fruit, effects of spraying upon the root development 

 of the vines, results of fertilizer experiments, the effects of resanding, and 

 methods of destroying injurious insects. Numerous new observations and 

 discoveries concerning injurious insects are presented, together with im- 

 portant observations on the work of parasites on injurious insects, one of 

 them not previously described. Observations on the movement of water 

 in the peat of the cranberry bog, as well as on the root development of the 

 cranberry, are presented, and the suggestion is made that some of the 

 highly improved types of blueberries may be cultivated upon a commercial 

 scale with greater profit than cranberries on bogs not provided with water 

 for flowage.
