Generally speaking it appears that there are no si)ecial cultural difllculties to 

 be met with in growing paprika peppers in favorable locations in this country. 

 The experimental crops growTi by the Department have been harvested with a 

 favorable mragin of profit. On the other hand, until a larger market is devel- 

 oped for the product the planting of paprika peppers can be easily overdone. 



Beport of the horticulturist, M. A. Blake and A. J. Farley (Neio Jersey 

 8tas. Rpt. 1912, pp. 69-96, pis. 5). — A brief general statement is given of progress 

 made on various projects in 1912, together with data on the time of spraying, 

 materials used, and cost of spraying in the Vineland peach orchards; harvest- 

 ing dates of various apples at the college farm for the years 1908 to 1912, 

 inclusive; a discussion of the nature of winter injuries to fruit trees noted on 

 page 352; a brief account of the division's new range of greenhouses; and a 

 description of experimental lime tests with My Maryland and Killarney roses. 



An analysis of the harvesting dates of apples shows a considerable difference 

 in the actual date of ripening of the various varieties in certain seasons and 

 leads to the conclusion that fruit should be picked according to its actual 

 maturity rather than at fixed dates. 



In lime tests with greenhouse roses two varieties. My Maryland and Killarney, 

 were grown in bench plats, each containing 15 sq. ft. of surface. Two plats 

 were kept as checks; two plats each received 270 gm. of ground calcium lime- 

 stone; and two plats each received 810 gm. of limestone when the plants were 

 benched in the spring of 1910. All of the plats received the same general fer- 

 tilizer treatment. Notes and data are given on the condition of the plats up to 

 the fall of 1912, when the seventh crop of roses was gathered and the experi- 

 ment discontinued. As indicated by the total yields of all the plats for the 

 entire experiment, the unlimed plats show a smaller number of flowers of all 

 grades (with one exception) of both My Maryland and Killarney than the plats 

 receiving 270 gm. of limestone, and the plats recei-sdng 810 gm. of limestone 

 produced more flowers of all grades than the plats receiving 270 gm. of lime- 

 stone. Killarney appeared to suffer much more from the increasing acidity in 

 the soil than My Maryland. In addition to reducing the number of flowers the 

 lack of lime appeared to reduce the length and vigor of the stems and 

 leaves. The color of the flowers on the slightly acid plats was somewhat 

 heightened, but when the growing shoots became very slender and weak the 

 flowers were very light in color. From the results thus far secured it is be- 

 lieved to be advisable to apply annually at least 270 gm. of ground limestone to 

 each 15 sq. ft. of bench surface, and that heavier applications may be bene- 

 ficial and desirable with certain soil types, varieties, and methods of culture. 

 Some extended studies with lime in the culture of roses are now being 

 conducted. 



Orchard spraying", TT. H. Alderman, N. J. Giddings, and W. E. Rumsey 

 {West Virginia Sta. Clrc. 7, pp. J^8, figs. 33). — This circular discusses the use of 

 spray machinery, preparation of sprays, and spray material, and briefly de- 

 scribes the more important diseases and insects of orchards and vineyards, 

 including suggestions for their control. 



Bational methods of pruning" grapes, V. C. M. de Ztji^iGA (Prog. Agr. y 

 Pecuario, 19 (1913), Nos. 832, pp. 483-485; 833, pp. 501-504).— A discussion of 

 various methods of pruning grapes, wath special reference to the reconstitution 

 of phylloxera-infested vineyards, based largely on observations made in the 

 experimental field of the enological station at Haro, Spain.
