HORTICULTURE. 143 



bola (Averrhoa caram^ola), bilimbi {A. Itiliinbi), atemoya (E. S. R., 31, p. 47), 

 and cherlinoya (Annona cherimoUa), and the budding of some of the cultivated 

 citrus fruits on the calamondin {Citrus niitis). 



Tbe experiments carried out during the dry season of 1913-14 have shown 

 that the durian and carambola may be readily shield budded with the inverted 

 T bud. The carambola and bilimbi budded on each other and the bilimbi budded 

 on itself have thus far failed to grow. Atemoya buds well on the mamou but 

 not so well as on the custard ai)ple, which imparts to the atemoya a very char- 

 acteristic upright growth. The cherimoya and atemoya do not thrive on the 

 soursop but the cherimoya can be budded on the sngar a])i)le, custard apple, and 

 mamon with good results. Of the Philippine citrus fruits the orange, mandarin, 

 lime, and pomelo have grown well on the calamondin. There is a tendency for 

 the calamondin to dwarf the more robust species grafted upon it. Repeated 

 attempts to graft and bud seedless breadfruit upon the seedling type have 

 failed absolutely. The author lias met success in budding avocados and large- 

 fruited guavas. 



The improvement of medicinal plants, F. A. Miller (Proc. Ind. Acad. 8ci., 

 1912, pp. 115-120, figs. Jf). — Some preliminary notes are given on selection 

 studies of belladonna, henbane, stramonium, Digitalis, and Cannabis which are 

 being conducted with the view of increasing the percentage of alkaloids. The 

 results, although not conclusive, indicate that not only greater yields but better 

 and more reliable medicinal products can be secured through, judicious selection. 



Goldenseal under cultivation, W. Van Fleet {U. 8. Dcpt. Agr., Farmers^ 

 Bui. 613 (lOlJf), pp. 15, figs. 5). — This describes the goldenseal plant and gives 

 an account of its production and culture, both under lath shed shade and under 

 forest tree shade. Information is also given relative to digging, curing, dis- 

 eases and pests, yield, and cost. 



The author concludes in general that regarded as a minor money crop, golden- 

 seal is well adapted for small growers who can meet the special requirements of 

 the plant. Since goldenseal requires essentially the same conditions as ginseng 

 (E. S. R., 29, p. G39), although easier to grow, it is suggested that it may prove 

 a desirable side or succession crop with ginseng. 



Dreer's hints on the growing of bulbs {PlnladeJpliia, lOlff, pp. 6-'f, figs. 20). — 

 A practical manual of information on the indoor and outdoor culture of bulbs. 



The dafeodil yearbook, 1914 (London: Roy. Hort. Sac, 19U, pp. IX+lJfO, 

 pis. 37). — A yearbook of information dealing with various phases of daffodil 

 culture, varieties, diseases, insect pests, exhibitions, etc. In addition to infor- 

 mation dealing principally with Great Britain, papers and notes from Australia, 

 New Zealand, Holland, and the United States are also included. 



Practical help on landscape gardening-, W. Millee {lUinois 8ta. Circ. 116 

 (1914), PP- 16, figs. 9). — This circular briefly outlines the assistance rendered 

 to the people of the State by the division of landscape extension of the Uni- 

 versity of Illinois, and contains instructions for securing illustrated lectures, 

 advice, and plans for home grounds, streets, roads, library, school, and other 

 public buildings. 



Luther Burbank, his methods and discoveries and their practical applica- 

 tion, edited by J. Wuitson and R. J. and H. S. Williams (Neio York and Lon- 

 don, 191.',, vols. 1, pp. 308, figs. 105; 2, pp. 308, figs. 105; 3, pp. 308, figs. 105).— 

 "Volume 1 of this work comprises a survey of the breeding methods employed 

 by Burbank, volume 2 gives the history of a number of his productions, and 

 volume 3 deals with various phases of plant propagation, such as pollination, 

 grafting, plant affinities, fixing traits, and selection. The work as a whole was 

 prepared from Burbank's original field notes under the direction of a board of 

 editors.
