of 800 lbs. of the above mixture with 150 lbs. acid phosphate, a 24 per cent increase over the 

 unfertilized plot. Increasing the amount to 1050 lbs. plus 800 lbs. acid phosphate increased 

 the yield only 12 per cent, and the berries were oversized and soft. — /. K. Shaw. 



1959. Bergman, H. F. Observations on the accumulation of carbon dioxide from straw- 

 berries in refrigerator cars. Science 53 : 23. 1921 . — During the years 1918 and 1919 the writer 

 made observations on the COa and O2 content of air in refrigerator cars, and the effect of ven- 

 tilation on the accumulation of CO2. In the tests of 1918, berries were loaded at a tempera- 

 ture of about 68-70°F., and one car was ventilated by raising the hatches at diagonal corners 

 of the car. In the tests of 1919, the berries were loaded at a temperature of 76-78°F., and one 

 car was ventilated by raised hatches. From the table it is apparent that there is no great 

 accumulation of CO2 in the air of unventilated cars in transit. The maximum of 2.5 per cent 

 dropped to 0.7 per cent when the car was iced, and again increased to 1.3 per cent, never ex- 

 ceeding this amount during the remainder of the journey. In ventilated refrigerator cars 

 the percentage of CO2 is lower. It may, while the cars are standing, become nearly or quite as 

 great as in unventilated cars, but when the cars are moving it drops to 0.2-0.4 per cent. It 

 is concluded that the accumulation of CO2 in unventilated refrigerator cars is apparently 

 not sufiBcient, in the case of strawberries, to cause injury to the berries. — A. H. Chivers. 



1960. Bergtholdt, J. E. President Bergtholdt's address to the Californians. Amer. 

 Nurseryman 33^ : 8. 1921 . — This address consists largely of suggestions for the betterment of 

 the California Association of Nurserymen but it includes statements to justify the high price 

 of nursery stock. Data are presented to show that California-grown fruit trees are cheaper 

 than eastern-grown stock of the same size and quality. — The nurserymen cannot, on the aver- 

 age, secure a yield of trees greater than 70 out of 100 planted, and out of the 70 not more than 

 49 will, over a period of years, be sold. This loss of over 50 per cent must be absorbed by the 

 trees that are actually sold; this in part explains the high price of nursery stock. — J. H. 

 Gourley. 



1961. BxTNYARD, Edward A. The length of stem in pears and apples. Jour. Pomology 

 1 : 20-22. 1 fig. 1919. — Fruits borne at the center of a cluster, in the case of app es, or at the 

 tip of the cluster base, in the case of pears, have shorter stems than those borne laterally. 

 The great variation in the length of stem within a variety renders this character of little value 

 in the classification of varieties. — L. H. MacDaniels. 



1962. BuNYARD, Edward A. Seedling apples — a record of some growers' experiences. Jour. 

 Pomology 1 : 110-115. 1920. — A discussion of some of the results of apple breeding experiments 

 in England, Canada, and the United States. It is concluded that most of the varieties that 

 have been used in crossing behave as if genetically pure, and transmit their characters to 

 the seedling. A method of bringing seedlings into early bearing by cutting the tap root is 

 briefly described. ■•—Z/. H. MacDaniels. 



1963. Chambers, F. S. Report of the research committee of the American Cranberry 

 Growers' Association. Proc. Ann. Meeting Amer. Cranberry Growers' Assoc. 50: 7-10. 

 1920. — Investigations conducted since 1913 appear to indicate that various cranberry soils 

 have different degrees of acidity. Cranberries will grow well in soils of slight acidity, also 

 in soils that are very acid. Pi,ed-root (Ceanothus americanus) and double-seeded millet can 

 apparently tolerate a greater acidity than the cranberry. — J. K. Shaw. 



1964. Chasset, L. En culture fruitiere intensive: croisillon et gobelet nain; comparison 

 des deux formes. [Comparison of the cross-bar and dwarf-goblet forms in intensive fruit 

 culture.] Rev. Hort. 92: 191-192. 1920. — When spaced 2 meters apart, the cross bar type of 

 tree would possess, when developed, 33,200 meters of wood capable of carrying fruit-spurs, 

 whereas the goblet type would possess 50,000 meters. On rich soils, however, it would be nec- 

 essary to space the goblet-form trees 3 meters apart, in which case the length of spur-pro- 

 ducing wood would be reduced to 33,000 meters, but all of this would be advantageously
