1440. Taft, L. R. Commercial cherry culture. Proc. Amer. Pomol. Soc. 35: 106-118. 

 1917 [1919]. — Statistics from tlie 1910 census arc used to show the number of trees and size 

 and value of the cherry crop in the 7 leading states. A map of the Michigan fruit belt is given 

 with data on the effect of Lake Michigan on the land temperature. Recommendations are 

 made for the proper soil and site for orchards, age of trees for planting, best varieties, and 

 cultural treatment. The proper methods of harvesting and marketing the crop are discussed, 

 together with the extent of the canning industry in Michigan. It is also suggested that sour 

 cherries could profitably be grown in Massachusetts and other New England states. — E. C.

 activity. Proc. Amer. Soc. Hort. Sci. 17: 83-86. 1920 [1921]. — A demonstration community 

 packing house was constructed at state expense at Inwood, West Virginia, in 1920. During 

 the first season (1920) 108 cars were shipped from the plant. Growers were taught the great 

 value of proper spraying and packing as a prerequisite for successful marketing. — E. C.

1446. Waring, J. H. The probable value of trunk circumference as an adjunct to fruit 

 yield in interpreting apple orchard experiments. Proc. Amer. Soc. Hort. Sci. 17: 179-185. 

 1920 [1921]. — Correlation studies were made between the inches gained in trunk circumference 

 and the pounds of fruit produced in several Pennsylvania orchards where fertilizer experi- 

 ments had previously been carried on. In addition, the coefficients of variability for circum- 

 ference and yield were determined. — "In-as-much as trunk circumference records used in 

 conjunction with records of the production of fruit, have enabled us to reach certain truths 

 that had not been discovered by our study of production records alone, we conclude that trunk 

 circumference records do have a decided value which may closely approach the value of the 

 yield records themselves as an aid to the correct interpretation of results in apple orchard 

 experiments." — E. C. Auchter. 



1447. Webb, Weslet. Progress of pomology on the Delaware-Chesapeake peninsula. 

 Proc. Amer. Pomol. Soc. 35 : 182-186. 1917 [1919].— The early history of fruit growing in Dela- 

 ware is given. Attention is called to the fact that the Peninsula leads the world in strawberry 

 production. The peach fertilization experiments of C. A. McCue, which demonstrate the 

 value of nitrogen in peach orchards, are reviewed. The apple varieties commonly grown are 

 Stayman Winesap, Yellow Transparent, Early Ripe, Williams Early Red, Jonathan, Grimes, 

 Rome Beauty, and Paragon. Apple grading laws and fruit sizing machines have helped to 

 raise the standards of packing. — E. C. Auchter. 



1448. Wester, P. J. Plant propagation and fruit culture in the tropics. Bur. Agric. 

 Philippine Is. Bull. 32. 134 P-, ^3 pi. 1920. — The bulletin is a general manual covering the 

 field indicated by the title. While this publication applies primarily to the subjects in the 

 Philippines, much of the data assembled are applicable to other tropical countries, and it 

 should be of great value to all residents in the tropics who are interested in the subject. —
