Varieties of tree fruits for New Jersey, M. A. Blake {'New Jersey Stas. 

 Circ. Jil, pp. 8). — In this circular lists are given of varieties of apples, peaches, 

 pears, cherries, plums, and quinces that are adapted for the home orchard and 

 for commercial planting in New Jersey. Suggestions are also given relative to 

 age and size of trees to plant and time of planting. 



Spring versus fall planting", F. M. Clement {Ann. Bpt. Fruit Growers' 

 Assoc. Ontario, 46 {1914), pp. 51-55, figs. 2). — A brief discussion of the relative 

 merits of spring v. fall planting, including results of experiments conducted 

 with plums and pears at the Vineland Experiment Station, Ontario. Six Heine 

 Claude plums and six Bartlett pears were planted in the falls of 1911, 1912, 

 and 1913, and duplicate check rows in the springs of 1912, 1913, and 1914. 

 In every case the difference in growth Is thus far in favor of the fall planting. 



In connection with this experiment the value of dynamiting holes for fruit 

 trees was tested. ' The dynamited trees have made less growth than either the 

 fall or spring planted trees. This is attributed to the fact that the trees were 

 planted immediately after the holes were dynamited, tlie soil subsequently 

 drying out badly. 



Spray calendar for Georgia, T. H. McHatton and J. W. Firor {Ga. State 

 Col. Agr. Circ. 8 {1915), pp. 8, fig. 1). — This circular contains directions for 

 preparing spray mixtures, with schedules for apples, peaches, grapes, pecans, 

 and vegetables. 



Apple culture in Georgia, T. H. McHatton, J. W. Fikor, and C. M. Kigeb 

 {Bui. Ga. State Col. Agr., No. 85 {1915), pp. 36, figs. 24).— A popular treatise, 

 discussing the orchard location and site, preparation of the land, laying out 

 and planting the orchard, pruning, cultivation, fertilizers, frost injury, protect- 

 ing the trees from rodents, and insect pests and fimgus diseases and their 

 control. Descriptive notes are given of varieties recommended for different 

 sections of Georgia. 



Yields of apple trees at different ages, W. T. Macoun {Ann. Rpt. Fruit 

 Ch'owers' Assoc. Ontario, 46 {1914), pp. 68, 10-12). — In a previous publication 

 data were given on a number of varieties of apples growing at the Central 

 Experimental Farm, showing the yields of the best yielding trees of each 

 variety from the third until, in a number of cases, the twenty-second year after 

 planting (E. S. R., 27, p. 343). In the present paper the record of these trees 

 has been extended to the twenty-sixth year after planting for a number of the 

 varieties. The data are given with a view to showing the importance of keeping 

 individual tree records. 



What does it cost to grow a barrel of apples? M. Ells {Canad. Hort., 38 

 {1915), No. 5, pp. 121, 122). — During the past season the author kept an account 

 of three different orchards on different parts of the farm, involving some 32.-5 

 acres with a crop yield of 1,600 bbls. The data secured for the one year showed 

 a cost of production of $1.32 per barrel. 



The cherries of New York, U. P. Hedrick et al. {New York State Sta. Rpt. 

 1914, Pt. 2, pp. XII-\-371, pis. 57).— This is the fourth of the station's mono- 

 graphs on the fruits of temperate North America (E. S. R., 27, p. 40). 



Chapter 1 discusses cherries in relation to kindred fruits, the distribution 

 of cultivated ciierries, uses, amelioration, and the tree and fruit characters 

 of the cherry. A brief conspectus is given of the edible species of Prunus 

 followed by a fuller conspectus of the subgenus Cerasus to which cherries 

 belong. Chapter 2 takes up the history of cultivated cherries both in Europe 

 and America. Chapter 3 deals with cherry culture, consideration being given 

 to the extent of the industry, stocks for cherries, cherry climates and soils, 

 blooming dates of varieties of cherries as observed in the station orchard for 

 6318°— No. 5—15 4
