uted. Numerous interesting variations in growth on the dif- 

 ferent plots were noted during the season, but it is yet too 

 early to present the details of treatment, or to discuss the 

 effects of the different fertilizer applications. 



Cranberry Substations. 



The station is carrying on work with cranberries along two 

 distinct lines and in two different localities: (1) the study of 

 cranberry insects in Wareham ; (2) fertilizer experiments with 

 cranberries in Falmouth. 



Work on Cranberry Insects. — The station was fortunately 

 able to command once more the services of Mr. H. J. Franklin 

 for the study of problems connected with cranberry insects. 

 Mr. Franklin spent the entire season, from the middle of April 

 to the middle of October, in the cranberry district, most of the 

 time in the town of Wareham. As the result of the season's 

 work, our knowledge of cranberry insects has been greatly 

 extended at numerous points, and the tentative conclusions 

 reached as a result of the first season's work have been in many 

 cases confirmed. A bulletin presenting the results of the first 

 season's work, and containing advice as to the treatment to be 

 adopted for the prevention of injury from the more important 

 cranberry insects, has been issued during the year. This has 

 been sent to all cranberry growers whose addresses we were 

 able to obtain, — about 1,500. It has been found that the in- 

 jury due to many insects can be for the most part prevented by 

 a thorough destruction of vegetation around the shores of the 

 bog, and suitable control of the water in flooding. Methods of 

 spraying have been found to be fairly effective in some cases. 

 The bulletin on cranberry insects, which gives all details, can 

 still be furnished on application. 



Fertilizer Experiments. — The fertilizer experiments in Fal- 

 mouth are located in what is known as the Red Brook bog, be- 

 longing to Mr. N. H. Emmons of Boston and Falmouth. The 

 present is the second season that these experiments have con- 

 tinued, and results which are believed to be of considerable 

 significance have been obtained. The possibility of making 

 exact comparisons between different fertilizer treatments has
