HORTICULTURE. 



[Report of the horticulturist] (New Mexico Sta. Rpt. 1909, pp. 24-35). — 

 An outline is given of the year's work with fruits, vegetables, and ornamentals, 

 including some data on a study of the frost resistant qualities of the fruit buds 

 of different varieties of peaches durnig the spring of 1909 and fertilizer tests 

 with onions in 1907-S. The plan is given of a new pear orchard containing 

 78 varieties. The newer work includes cultural tests of peaches, grapes, and 

 various vegetables under irrigation on the mesa land. 



The observations of the hardiness of peach fruit buds have shown thus far 

 that the freshly opened buds are more cold resistant that the older buds or 

 those which have lost the petals. Many of the freshly opened buds were un- 

 harmed even when the mercury dropped to 24° F. for a short period. The 

 chilli experiments which have been conducted for a number of years practically 

 failed in 1908 on account of a wilt disease which appeared in July and August. 

 The trouble is being investigated. 



Real facts about the problem of fall planting v. spring planting (Gard. 

 Mag. [N. Y.]. 12 {1910), Xo. 3. pp. ltS-122. figs. ,3).— This is a symposium of 

 actual experiences by expert planters in widely separated sections with the aim 

 of bringing out the comparative merits of fall versus spring planting of trees, 

 shrubs, and herbaceous plants. The numerous practical suggestions given indi- 

 cate as a whole that special conditions are apt to govern each individual planting 

 operation and that every planter must use his own judgment as to whether he 

 should plant in the spring or fall. 



Uniformity of varietal character in garden vegetables, W. W. Tracy 

 (Trans. Peninsula Hort. Soc. [Del.]. 23 (1910), pp. 9S-10Jt).—A discussion of 

 this subject in which the author brings out the great need on the part of the 

 planter of a more complete and accurate knowledge of varietal differences and 

 their adaptation to specific soil conditions, cultural practice, and market re- 

 quirement; also the desirability of raising stocks of seed which will be more 

 uniform in varietal character. 



Celery growing, storing and marketing, H. M. Howard (Mass. Crop Rpt., 

 23 (1910), No. .'i, pp. 30-36). — A popular article on celery growing, discussing 

 soils, varieties to plant, methods of growing plants, prepai'ation of the soil, 

 cultivating, bleaching, storing, and marketing. 



History of fruit growing in Alabama, P. J. Berckmans (BuL Agr. Dept. 

 [Ala.]. No. 36, pp. 103-101). — A paper on this subject read before the Alabama 

 State Horticultural Society. 



[Report on horticulture] (County Northumb., Ed. Com., liul. 1), pp. 68- 

 70). — Descriptive notes are given of the ex|)orimentaI fruit plantation at the 

 Agricultural Experiment Station, Northumberland County. England.
