HORTICULTURE. 241 



vided tlio individual trees were in active growth, although the buds set early 

 in the year were ahead in point of growth. 



Although the inarching method of propagating the mango has been to a large 

 degree supplanted by budding, inarching is still considered very useful in propa- 

 gating valuable trees that have become pot-bound or otherwise stunted. 



Th(! use of cover crops on the slopes in the station orchards during the rainy 

 seast)n has become an established practice. The jack bean and cowpea of the 

 clay type have given the l)est results of any legumes tested. The pigeon pea 

 {Cujiiiiiis indicKs), although a valuable leguminous plant, grows too tall and 

 woody to be turned under easily. 



In some tests in drying roselle fruits with the view to making them less 

 bulky and less susceptible to decay during shipment, it was found that 12.8 lbs. 

 of the fresh fruit were required to jiroduce 1 lb. of dry calyces. It is calculated 

 that to pay as well as the fresh fruit the dry calyces can not be sold for less 

 than 4.J cts. per pound plus the cost of drying. Since less than half this price 

 was offered for them by preserving companies on the mainland, it appears more 

 profitable to market the Hawaiian roselle directlj' in the form of jams and 

 jellies. 



An outline is given of the system used by the horticultural division in keep- 

 ing records of plantings and the life history of plants. 



Report of professor of horticulture, P. ,T. Shaw (Ann. Rjtt. Sec. Ayr. Xora 

 l^cotia, 1909, pt. J, pp. 38-57, fly. 1). — This consists of an outline of the educa- 

 tional work conducted at the agricultural and normal colleges in Truro, together 

 with a statement of the condition of the model orchards located throughout the 

 I'rovince. 



Bean growing'. W. F. Kavkn {Michigan ,Sta. Bid. 259, pp. 89-96). — This bul- 

 letin contains information relative to the ordinary cultural methods employed 

 in growing the field bean under Michigan conditions. It discusses the suita- 

 bility, preparation and fertilization of soils, varieties, cultivation, harvesting, 

 marketing, and threshing, and diseases of beans. Tables are also given showing 

 the acreage, yields, and average prices paid Michigan farmers for beans for 

 each mouth during a 10-year period. 



Nursery stock and soils pertaining' to the production of types and sizes, 

 O. G. Wilson (Spec. Crops, n. scr., 9 (19 10), \o. 93. pp. 333-337, flys. J).— 

 Illustrations are given of favorite types of ginseng roots as grown by the author, 

 together with a discussion of the principles to be observed in order to raise good 

 roots, which are given as proper soil, deep high beds with the proper mulch, 

 and absence of the most rainfall during the first season. 



Fertilizer experiments with tomatoes, K. Weydahl (Norycs Landhr. Ilois- 

 l-olca Sh-r., 1909, A'o, 9, pp. l.'i, pis, J/). — Pot experiments with tomatoes are 

 reported in which it was shown that the tomato plant makes heavy demands 

 on the supply of easily available nitrogenous fertilizers in the soil but requires 

 only light supplies of phosphoric acid and potash. 



German fruit culture, R. Goethe, F. Ihne et al. (Arb. Dent. Landic. GesclL, 

 1908, Xo. 150. pp. XIV+320+8, flys. lO.'i, maps 2).— This is essentially a manual 

 of information relative to the German fruit industry. 



Part 1 contains the results of the German fruit tree census for the year 1900, 

 tog«>ther with short descriptions of fruit growing in the various kingdoms and 

 provinces of the (ierman Emi)ire. In part 2 considerati(m is given to climate, 

 soils, and tree physiology. I'art .'{ takes up the details of intensive and exten- 

 sive fruit growing, including information relative to the re(iuirements of various 

 fruits, varieties and races, planting operations and subsequent orchard manage- 

 incnl, .111(1 combating insect jiests, diseases, and other enemies. Part 4 discusses 

 imports and exports of fruits, yields, marketing, commerce, and profits. Part 5
