commercial. The farm orchard is no factor in the commercial industry. Increased produc- 

 tion is due to the commercial orchard. The survey shows seven major apple producing 

 regions as follows: New York, New England, the Shenandoah, Cumberland and Piedmont 

 regions, Michigan and Illinois, the Ozark and Missouri River region, the western irrigated 

 region, and the Washington region. There are six or seven minor regions. The future of the 

 apple industry is very promising. Apple production does not respond quickly to the law of 

 supply and demand. Some of the regions are at maximum production and as a result of little 

 planting since 1910, it seems not improbable that a shortage with high prices will result in 

 the near future. Increased population, movement to cities, the cessation of war with the 

 probable extension of foreign markets will all aid the commercial outlook.— C. J. Shirk.

926. Greene, Laurenz. 1917-1918 winter injury to apple trees. Rept. Iowa State 

 Hortic. Soc. 53 : 119-124. 2 pi. 1918.— The author reports the "injury extending from north- 

 eastern part of the United States, south and west to the Ohio and Mississippi River, becoming 

 more severe farther east and north." "The injury was most severe on trees from three or four 

 years of age to those twelve or fifteen years of age. Newly planted orchards of one or two 

 years largely escaped injury. Those twenty or more years of age suffered very much less, 

 although farther east these older trees, under certain conditions, suffered very much more." 

 The paper gave as varieties most injured: Indiana: Baldwin, Stayman, Ben Davis, York 

 Imperial; In New York: Baldwin, King, Rhode Island Greening, and Ben Davis. The 

 Winesap in Indiana was fairly resistant. "In the case of young trees, anything that checked 

 the growth early and ripened the wood reduced the injury. Young trees on poorly drained 

 soil suffered less." — L. H. Pammel.
