1042 EXPERIMENT STATION RECORD. 



the green louse or aphis," the latter being very abundant, especially on 

 young trees. It has not been found possible to rid the trees of them 

 by kerosene emulsion. The apple scab is seldom seen. Notes are 

 given on 20 varieties of Hungarian apples received from the Division 

 of Pomology of this Department. "There were 3 trees of each kind, 

 one of which had been grafted on a whole root, one on the upper half 

 of a root, and one on the lower half of a root/' Grafts on the lower 

 half of the root made a slightly better growth than the others, and 

 those on whole roots slightly poorer. In a test of northern as compared 

 with southern grown apple nursery stock, Missouri- grown trees aver- 

 aged 10 days earlier in starting than Georgia and Alabama stock, but 

 before the end of the season there was no difference between them. 



In a trial of Japanese as compared with French pear stocks for the 

 South, Bartlett pears on the former were from the outset the more 

 vigorous, and at the end of three seasons' growth averaged twice the 

 size of those on French roots. In a trial of the Stringfellow root-pruning 

 method with 8 varieties of peaches and 2 of pears, neither increase nor 

 decrease of vigor could be detected in the root-pruned trees. 



Observations made on the blooming seasons of 4G varieties of plums 

 are given. The varieties are grouped as to time of blooming in the 

 neighborhood of Auburn, each group comprising those blooming near 

 enough together in ordinary seasons to effect cross pollination. A test 

 of spraying with whitewash to retard blooming (E. S. K., 9, p. 835) 

 showed little if any effect on time of budding. 



Japanese persimmons, it is stated, grow readily in all parts of the 

 State and bear well. Varietal notes are given on 9 sorts. Okame, 

 Yeddo Ichi, Costata, and Yemon are recommended as the best market 

 kinds. 



Apples in Pennsylvania, G. C. Butz (Pennsylvania Sta. Bui. 43, pp. 

 i7)._This is a popular bulletin, giving notes on soil, tilling the soil in 

 young orchards, cultivation in bearing orchards, fertilizers, the trees, 

 pruning at time of planting, distance to plant, pruning bearing trees, 

 top grafting or double working, choice of varieties, preservation of 

 apples, spraying, insect enemies, and fungus diseases. The greatest 

 activity in Pennsylvania in the planting of apple orchards on a large 

 scale is displayed at present in the southern and southwestern parts of 

 the State. The author considers the York Imperial a variety of special 

 promise in Pennsylvania. 



Among the insect enemies of the apple are mentioned the codling 

 moth (Carpocapsa pomonella), borers, oyster-shell bark-louse (Mytilaspis 

 pomorum), cankerworm (Anisopteryx pometaria), aphis [Aphis mail), and 

 tent caterpillar (Clisiocampa amerioana), and remedies are given. 



Brief notes are given on the apple scab (Fusicladium dendriticum), 

 rust (Roestelia pirata and Gymnosporangiion macropus), and leaf spot 

 (Thyllosticta limitata), and remedies are suggested. 



Tests of strawberries, raspberries, blackberries, and grapes, J.
