1887. Anonymous. [Palmer, E. F.] Report of the Ontario Horticultural Experiment 

 Station, Vineland Station, Ontario. 1918: 1-40. 1919.— A progress report of experimental 

 and breeding work in horticulture.—^. F. Palmer. 



1888. Anonymous. Blooming and ripening season of various fruits. Rept. Hort. Exp. 

 Sta. Vineland Sta., Ontario 1918: 24-26. 1919.— A summary of the blooming and ripening 

 dates of commercial varieties of apples, apricots, cherries, peaches, pears, plums and grapes. 

 The dates given cover generally a period of from three to five years' observations. — E. F. 

 Palmer. 



1889. Anonymous. Raspberry breeding. Rept. Hort. Exp. Sta. Vineland Sta., Ontario 

 1918: 14. 4 fig. 1919.— Seedlings of the wild forms of Ruhus occidentalis, R. strigosis, and 

 hybrids of these species and of cultivated varieties have been fruited and described. Seed- 

 lings of R. occidentalis came practically true from seed and as a whole were nearly equal to 

 the cultivated variety Gregg. R. strigosus seedlings also came true from seed. Hybrids of 

 R. occidentalis (wild black) X R. strigosus (wild red) indicated a compromise in growth and 

 foliage characters. The fruit was all of the purple cane type. — In a reciprocal cross of these 

 species, plants and fruit all closely resembled the R. strigosus parent. — -From a cross of 

 Gregg (black) X Cuthbert (red) 152 plants were fruited and bore fruit in the approximate 

 ratio of 1 red to 4 black to 16 purple cane. The reciprocal cross gave all red raspberries. —

 Soc. Nation. Hort. France 21 : 268-269. 1920.^Gives results of ringing branches of the peach 

 trees to show advantages on earliness, size, and increased yield due to ringing. — H. C.

1892. Ballou, F. H., and I. P. Lewis. Orchard rejuvenation in southeastern Ohio. 

 (Second Report.) Ohio Agric. Exp. Sta. Bull. 339. 42 p. 1920.— On thin, poor, upland soils a 

 quickly available supply of nitrogen was found to be essential. Phosphorus was beneficial 

 but potash gave poor returns. Annual applications of 5 pounds per tree per year each of 

 nitrate of soda and acid phosphate used in connection with straw mulch gave practically 

 the same results as 10 pounds of each fertilizer not used in connection with a straw mulch. 

 Animal sources of nitrogen and phosphorus (tankage and bone) were found to be much less 

 satisfactory because they act too slowly where quick results are desired. Orchard rejuvena- 

 tion in southeastern Ohio has been proved to be highly profitable commercially. — R. C. 

 Thomas. 



1893. BixBY, W. G. The butternut and the Japan walnut. Amer. Nut. Jour. 10: 76-79. 

 1919. — There are three groups of walnuts: (1) butternut group; (2) black walnut group; and 

 (3) Persian walnut. It is hardly possible that Juglans cordiformis and J. sieboldiana, both 

 belonging to group (1), are hybrid between J. cathayensis, group (2) ,and /. regia var. sinensis, 

 group (3), because nuts show no suggestions of peculiar interior shell structure of group (3) 

 or (2) ; hence hypothesis advanced to that effect is disproved. The rough shelled Japan wal- 

 nut may be due to black walnut pollen. There is possibility of developing a nut with the 

 fine flavor of butternut and the smooth thin shell of Japan walnut, and having a long northern 

 and southern range. — E. L. Overholser. 



1894. BixBY, W. G. The 1918 nut contest. Amer. Nut. Jour. 11: 72-74. 1919.— Author 

 tabulates new score-card. Six of the characteristics can be quantitatively measured. The 

 cracking quality is the ratio of the weight of the kernel easily extracted to the total weight 

 and is expressed in per cent. — E. L. Overholser. 



1895. BixBY, W. G. Nuts without Inner shell. Amer. Nut Jour. 11: 37. 1919.— Author 

 finds nuts without inner shell partition are not entirely unknown even with species which
