16 EXPP:RIMEXT station. [Jan. 



vidod nozzles and Skinner nnions and loaned the station a Skin- 

 ner drillinii' maoliine. 



The small jnece of upland referred to in the last re])ort as 

 desirable in order to give better access to our building has been 

 purchased during the year. 



The Crop of 1011. 



The yield of fruit on the station bog during the past year was 

 in round numbers 850 barrels of berries. These were sold for 

 the sum of $4,088.83. The ordinary running expenses for the 

 season amounted to $1,817.08. The bog, therefore, yielded a 

 net income over and above ordinary running expenses of $3,- 

 171.25. 



The crop of the season was probably better than the average 

 crop will be, and it sold for good prices. We can hardly antici- 

 pate so large a net income annually, but there would seem to 

 be no question that the product of the bog will be sufficiently 

 large to furnish a considerable share of the funds that will be 

 needed for paying the costs of experimental work. 



Principal Lines of Cranherry ^Vorh. 

 Three principal lines of investigation with cranberries are in 

 progress. These relate respectively to the fertilizer require- 

 ments of the crop, the relations of insects to the cranberry indus- 

 try, and the study of injurious fungi. 



Fertilizer Expert men ts. 



The fertilizer exjieriments in Red Brook bog at Waquoit have 

 again given indecisive results. These experiments will be dis- 

 continued. We have found it exceedingly difficult to care for 

 them properly on account of their distance from our center of 

 ojierations, and we are convinced, moreover, that certain natural 

 inequalities in the character of the bog soil in the different plots 

 must always considerably reduce the value of the results ob- 

 tained. 



During the past season a new series of ])lots has been laid out 

 in the station bog. The results of the season do not show a 

 well-defined benefit followinc; from the use of either of the
