caused by finigons disease. In tlie ojiiiiion of the writer it was 

 caused (as is the russetiiig- of apples) by tlie dei^osition of 

 corky tissue in the skin of the fruit. Dr. Shear, in examining 

 berries with these rough areas, found no fungus in connection 

 with them. The difference, shown in Table X., between Plots 

 D and E was probably due to the diifcrence in the time of pick- 

 ing the berries. 



These rough areas are usually more abundant among berries 

 grown on '' hard bottom " than among those grown on peat. 

 Berries grown on " hard bottom " are usually, other conditions 

 being the same, better keepers. This well-known fact, together 

 with the experience with the berries from the bee plot hero 

 noted, suggests that the roughening of the fruit here discussed 

 may be relied upon to some extent as an indicator of the keep- 

 ing quality of Early Black berries. The fruit of the Late 

 Howe variety is sometimes streaked with irregular, vein-like, 

 red lines during ripening, and these lines appear to be of the 

 same nature as the rough areas on the Early Black fruit, for 

 they are most prevalent, as a rule, on berries grown on " hard 

 bottom," and occasionally rough areas are associated with them, 

 the roughness being superficial while the red veining is deeper 

 within the tissues.

The Waquoit experiments were not continued, though the 

 plots w'ere examined just before harvesting and were found 

 without exception to have produced a very light crop. There 

 was apparently no evidence of any cropping effect from the fer- 

 tilizers used in the preceding seasons. 



The plots on the station bog at East Wareham w-ere fertil- 

 ized again, with the results showm in Table XL The fertilizers 

 were applied on June 25 and 2G. The lu^rries were all picked 

 with scoops on September 11 and 12. They appeared so uni- 

 form in color and so alike in most other respects that no 

 records were made, except those concerning their quantity, size 

 and keeping quality. Storage tests were carried out with ber- 

 ries from all the plots, beginning October 1 1 and ending De- 

 cember 13 to 17, the results of which gave no evidence that any 

 of the fertilizers, except perhaps the acid phosphate, had af-
