"were sprayed 1 times and the next year 3 times. Tables are given 

 showing the dates of picking, the weight of fruit at each picking, and 

 the computed yield per acre for both the sprayed and unsprayed plants 

 of each variety. 



In regard to varieties the author says: "The varieties giving the 

 largest early yields are Early Ruby, Potato Leaf, Prize Taker, Auto- 

 crat, and Canada Victor. The best varieties for main crop trucking- 

 are Paragon, Prize Taker, Perfection, World's Fair, and Climax. The 

 best varieties for the canning trade are Royal Red, Queen, Stone, Par- 

 agon, and Matchless. The best variety for late market or family use is 

 the Buckeye State." The first 4 sprayings increased the yield of ripe 

 fruit of all but one variety in 189G and of all but 3 varieties in 1897, 

 and, taking account of the green fruit at the end of the season, spray- 

 ing increased the yield in every case. In 1896 the average yield of the 

 sprayed plants was at the rate of 9.52 tons per acre and of unsprayed 

 plants 6.98 tons per acre. In 1897 yields of sprayed and finsprayed 

 plants were at the rate of 10.26 and 8.11 tons per acre, respectively. 

 It was found that infection of the blight may take place through the 

 agency of insects. Some Colorado potato beetles that were feeding on 

 blighted potatoes were placed on isolated and protected tomato plants, 

 other plants being kept as checks. The plants on which the beetles 

 were placed blighted, while the check plants showed no evidence of the 

 disease. 



Miscellaneous fruit notes, S. C. Mason and W. L. Hall (Kansas 

 Sta. Bui. 73, pp. 181-193). — Notes are given on 20 of Munson's hybrid 

 grapes. In summarizing the notes the author says : 



"All the Post Oak hybrids are tender in our climate and need winter covering. 

 All are vigorous growers except the Triumph hybrid, and all are late in blooming 

 and in ripening of fruit. Blood, Sweetey, aud Letoney give us a delicious j nice for 

 canning, aud doubtless would make a line wine; Carman is a very fair table grape; 

 Texas Highland is a better, but does not bear well. . . . 



"From this brief glance at all of these hybrids we may fairly infer, it seems to me, 

 that the pistillate parent exercises a stronger control over the character of the vine 

 than does the pollen-bearing parent, while the predominating influence of the male 

 (or pollen-bearing) parent can most often be detected in the fruit; aud further, that 

 the strong tendency toward tenderness from a Yitis vinifera cross is not escaped in 

 the third generation." 



Tests of the Mariana plum indicated that it can be used with good 

 results as a stock for grafting the varieties of American, Japanese, and 

 European plums. Apricots grafted on the Mariana stock made a vig- 

 orous growth, but there was an almost total lack of continuity in grain 

 of wood of stock and scion. A longitudinal section of a 6-iu. tree trunk 

 showed a sharply drawn line rising a little from the center to the out- 

 side. "Toward this line of .separation the -wood grain from each side 

 made a sharp curve inward, becoming parallel with it. A section ^ in. 

 in thickness was readily broken with slight pressure, breaking sharply 

 on this line across the entire section, except a small portion at the 

 center."
