the trees, which were 15 years old, had grown side by side in a garden 

 where they were apparently subjected to conditions all of which were 

 comparable except that of stock. Each tree bore about 300 fruits each 

 year and for three consecutive seasons the mature fruits were collected, 

 samples analyzed, and the averages tabulated. The color of the fruits 

 was very different, those upon the pear stock being green and those 

 upon the quince stock golden yellow, with a decided rose blush on the 

 side toward the sun. Some of the other differences of the two fruits 

 are shown in the following table:

From the foregoing table it is seen that the average weight, density, 

 acidity, and sugar content were in favor of the trees grafted upon the 

 quince stock. The estimated amount of sugar in the fruit of each tree 

 was 7 kg. for the tree upon the seedling stock and 11 kg. for the other. 



These figures are in the main confirmed by observations made some 

 years previous on winter Doyenne pear scions upon seedling pear and 

 quince stocks. 



The difference seems to be caused by a greater activity of the chloro- 

 phyll in the case of the scion upon the quince stock. 



Blackberries, dewberries, and raspberries, W. Paddock (New 

 York State Sta, Bui. Ill, n. ser.,pp. 281-294). — The bulletin is a report of 

 variety tests of small fruits for 1890. The following fruits were tested: 

 Blackberries, 27 varieties; dewberries, 4 varieties: black raspberries, 

 27 varieties ; red raspberries, 23 varieties ; purple raspberries, 7 varie- 

 ties; yellow raspberries, 6 varieties. Data in regard to date of plant- 

 ing, yield of fruit, duration of fruiting period, percentage of early and 

 late yield, percentage of canes winterkilled, etc., are given in tabular 

 form. Brief notes supplement the data of the tables. The author gives 

 the following summary : 



"Ancient Briton, Stone Hardy, Early Harvest, and Agawam were the most pro- 

 ductive blackberries on the station grounds in 1896. Snyder is valuable for its 

 hardiness. Mersereau is promising. 



"Lucretia is the only dewberry of commercial importance. Austin Improved 

 gives promise of being a valuable acquisition. 



"Of the early black raspberries Eureka and Hopkins were the most satisfactory. 

 Mohler, Hilborn, Babcock No. 5, and Pioneer were the most productive midseasou 

 varieties, while Mills, Ohio, and Ouonrtaga were the most productive late varieties.
