Cultural methods, cover crops, and fertilization in apple orchards, J. P. 

 Stewakt (Rpt. Bd. Agr. [N. //.], 33 (1913-1 >,), pp. 190-208).— In this paper the 

 tiuthor reviews some of the more practical results secured from the long-con- 

 tinued orcharding experiments in Pennsylvania (E. S. R., 33, p. 238). 



Thirty years in a home orchard, F. J. Heacocic (Country Gent., 81 (1916), 

 No. 20, p. 1013).— The author here presents a complete financial history, includ- 

 ing costs and returns, of a two-acre apple orchard. The total cost during 

 the period of 30 years was $1,837.39, and the total net profit $1,356.01. 



Experimental orchard work, 1915, W. S. Blair (Ann. Rj)t. Fruit Growers' 

 Assoc. Nora Scotia, 1916, pp. 184-211).— In continuation of previous Avork 

 (E. S. R., 33, p. 236) the results of cooperative orchard spraying experiments 

 conducted under the direction of the Kentville station in 1915 are summarized. 



The following general conclusions are drawn from the investigations as a 

 whole : 



Spraying before the leaves open, with special reference to the control of 

 scab, is not likely to give results sufficiently great to pay for its application. 

 Two foliage sprays thoroughly applied, one before blossoming or just after 

 the leaf buds open and the other just before the blossoms open, followed by 

 two applications after blossoming, will give practically clean fruit. The 1.008 

 specific gravity test strength of lime-sulphur is sufficiently strong to control 

 scab and a greater strength may cause injury to the foliage and fruit. 



Lime-sulphur alone Is nearly as good a fungicide as lime-sulphur arsenate, 

 but owing to insect injury the arsenate can not be safely omitted. Any of the 

 well-established brands of arsenate appear to give equally good results when 

 used with lime-sulphur. Lime-sulphur is equally as good as Bordeaux for scab 

 control and less liable to russet the fruit. Homemade concentrated and com- 

 mercial concentrated lime-sulphurs are equally effective for scab control if 

 used at the same specific gravity test. Soluble-sulphur arsenate is not as 

 effective as lime-sulphur arsenate and is liable to cause serious foliage injury. 

 Soluble sulpliur is more effective with arsenate of lead than without, this 

 being attributed to the greater adhesiveness of the compound. Barium chlorid 

 proved to be of no practical value for lessening foliage injury when added to 

 soluble-sulphur arsenate. A strength of soluble sulphur generally recom- 

 mended, 1.5 lbs. to 100 gal. of water, is about as good a fungicide as that of a 

 greater strength. 



Protecting the home apple orchard by dusting, D. Reddick and C. R. 

 Ceosby (N. Y. State Col. Agr., Cornell Univ. Ext. Bui. 1 (1916), pp. 14, figs. 

 8). — The authors here give directions for controlling apple diseases and insect 

 pests by the dusting method, with special reference to its use in small 

 orchards. 



A successful cold storage for apples, H. F. Hansen (Minn. Hort., 44 (1916), 

 No. 6, pp. 243, 244). — Directions are given for building a cold storage plant 

 suitable for storing apples on the farm. 



The principal parasites of the peach, W. W. Chase (Ga. Bd. Ent. Bui. 43 

 (1916), pp. -}7, pis. 16, figs. 2).— This bulletin gives brief accounts of the life 

 history and methods of control of the more important insect pests and diseases 

 of the peach. An article on the care and management of peach orchards, by 

 R. C. Berckmans (pp. 40-45), is appended. 



A promising new pear stock, F. C. Reimer (Mo. Bui. Com. Hort. Cat., 5 

 (1916), No. 5, pp. 167-172, figs. 2). — In continuation of previous observations 

 relative to the blight resistance of certain pear stocks (E. S. R., 33, pp. 53, 640) 

 the author conducted blight inoculation experiments on trees of a Chinese wild 

 pear (Pyrus callerynna), similar to those previously reported by Compere as 

 being blight resistant (E. S. R., 34, p. 55). These inoculations have shown
