HORTICULTURE. 51 



Where to cut in pruning, C. A. Keffer {Univ. Tennessee Record, 4 {1001), No. 

 1, pp. 5-)-5o) . — The author beheves that the best method of cutting off limbs is 

 through the base of the shoulder parallel to the trunk or limb on which the branch 

 to be removed is growing. 



On a hybrid of the Liberian and Arabian coffee tree obtained at Reunion, 

 E. BoRixvGE [Rer. Cult. Coloniales, 8 {1901), No. 68, pp. 1-7, figs. 5). — Illustrations 

 and descriptions are given of the leaves, flowers, and fruit of a natural hybrid 

 l)etw'.»en the Liberian and Arabian coffee trees. The hybrid resembles the Arabian 

 tree most in the form of its leaves, flowers, fruits, and the quality of the berries. On 

 the other hand, it is much more resistant to insect attacks and fungus diseases than 

 the Arabian coffee, and in these respects resembles the Liberian tree. 



Liiberian coffee; its culture and manipulation, V. Boltilly {Le cafeier de 

 Liberia, sa cnlture et sa manipulation. Pari.'<: A. Cludlanwl, 1900, pp. 137, pi. 1). — 

 Includes also a bibliography on the subject. 



The cultivated guavas and their botanical differences, J. B. Davy {Pacific 

 Rnnd Prt'ss, (U {1901), No. 11, p. 164). — A brief account of the genus with a key to 

 the species already introduce<l. 



A tendency to bisexuality in stra'wberries, U. P. Hedrick {Arner. Gard., 22 

 {1901), No. 327, p. 226). — The author has examined the history and sex of straw- 

 berries originated in America and has found that of the 185 varieties introduced 

 between 1834 and 1870, 96 varieties, or 52 per cent, were pistillate. Of the 513 varie- 

 ties originated between 1870 and 1900, only 136 varieties, or 30 per cent, were pistil- 

 late. Considering the whole period there was a somewhat uniform progressive 

 tendency from beginning to end for varieties to become bisexual. No reasons could 

 be assigned for this tendency, but climate, soil, cultivation, and the natural tendency 

 of strawberries to bear perfect flowers, as do most other jjlants of the same order, 

 are suggested. 



Second report on experiment in pinching raspberry shoots, E. S. Goff 

 ( Wi>fConsin Sta. Rpt. 1900, pp. 286-290). — The experiments along this line reported 

 in 1899 have been continued (E. S. E,., 12, p. 51), being modified only by allowing 

 5 shoots to grow to each plant instead of 4. The data for the two years are tabulated 

 and summarized. " Judgmg from the first two full crops, high jjinching, i. e., at 18 

 to 24 in., has apparently increased the yield of the Gregg raspberry, Imt has slightly 

 decreased the yield of the Cuthbert. Low pinching, i. e., at 12 in., has decreased 

 the yield of both varieties. Pinching appears to have slightly reduced the size of 

 the berries in both varieties. Pinching has evidently increased the growth of super- 

 fluous shoots in the (jregg variety." 



Making a cranberry bog, F. A. M.vkepeace {Agr. Epitomixf, 20 {1901), No. 4, 

 ]). 23). — The work of preparing the bog, grading, plantmg the vines, and harvesting 

 tlie crop is discussed. 



Grapes, F. S. Earle and C. F. Austin {Alabama College Sta. Bui. 110, pp. 55-91, 

 figs. 2). — This bulletin discusses in a general way soils and planting, training and 

 l)runing, cultivation, marketing, and insects and diseases and their treatment. One 

 of the most serious diseases at the station has been root rot. Out of 651 vines 

 planted in 1894, 483 vines, or a little over 75 per cent, are now dead, and the death 

 of tlie majority of them was caused by the root rot. Of the 16 varieties included in 

 this planting, only 2, Herbemont and Rulander, were entirely resistant to the disease. 

 It is thought that possibly these varieties may be used as stocks for less resistant 

 kinds. Various fertilizers have been used to note their effect in the control of the 

 disease. Among others heavy applications of kainit, lime, coal ashes, and stable 

 manure have been made, but with no marked results so far as the disease was con- 

 cerned. The southern part of the State seems to suffer more than the northern part 

 from the disease, and it is worse on sandy lands than on clays. 



Short descriptive notes are given on 94 varieties of grapes fruited in the station
