a wall exposed to the south or east, is preferable. The writer finds it 

 beneficial to take up the rhizomes as soon as the leaves wither, and keep 

 them until October in a dry but not too warm room. The outer segments 

 of the flower are recurved, furnished with hairs towards the base, with a 

 large black-purple spot in the centre, the ground colour being grey, 

 veined, and punctated with dark purple. The inner segments are erect, of 

 a fine bright rose colour, veined, and punctated with a deeper rose. The 

 petaloid segments of the pistil possess the same colour distribution as the 

 outer perianth segments, but with a deeper tone. In its dimensions and 

 appearance the plant holds the mean between 0. susianus (than which 

 it is slightly smaller) and 0. atropurpureus. — W. C. W. 



Onion Culture. By W. H. Jordan and F. A. Sirrine (U.S.A. Exp. 

 Stn., New York, Bull. 206 ; 12 1901). — The experiments were conducted 

 with a view to finding out the value of commercial fertilisers in Onion 

 culture. The manures were applied at the rate of 0, 500, 1,000, 1,500, 

 and 2,000 lb. per acre. The result is thus stated: — " The crops were 

 limited more by other conditions than by the extent of the plant food 

 supply. With the best conditions of season and water supply the 

 smallest amount of fertiliser supported the maximum crop." Again : 

 " The use of quantities above 500 lb. per acre was attended by danger of 

 financial loss." — F. J. C. 



Onions, Commercial Fertilisers for. By W. H. Jordan and 

 F. A. Sirrine (New York Agr. Exp. Stn., Bull. No. 206, December 

 1901). — The fertiliser used annually for three years contained 4 per cent, 

 nitrogen, 8 per cent, phosphoric acid, and 10 per cent, potash. The fourth 

 year the potash was changed to 5 per cent. The quantities used each 

 year on the five plots were : none, 500 lb., 1,000 lb., 1,500 lb., and 

 2,000 lb. per acre respectively. 



It was found that the best economic results were obtained by an appli- 

 cation of 500 lb. per acre. — J. P. 



Orange Conference (Bull. Bot. Dep. Jamaica, ix. Parts 1 and 2, 

 pp. 1-25). — This conference was arranged by the Board of Agriculture 

 on December 4, 1901, His Excellency the Governor presiding. The 

 subjects for discussion were on the various phases of the growth of the 

 Orange. The following points were discussed. Mr. W. Fawcett, Director 

 of Public Gardens, took a survey of the various organs, roots, stems, leaves, 

 flowers, and fruit. Mr. Levy discoursed on varieties. The propagation 

 and treatment were dealt with by Hon. T. H. Sharp. These papers were 

 followed by a discussion dealing with such points as nursery treatment, 

 drainage, tillage, pruning, irrigation, and insect pests, with the remedies for 

 each species respectively. — G. H.

 Stocks for the. Anon. (Agr. Jour. Cape G.H. vol. xix. Xo. 13, pp. 831- 

 836; 1901). — This article is an extract from the Report (U.S. Depart- 

 ment of Agriculture, Division of Pomology, Bulletin No. 4. Washington, 

 1891) on the Relative Merit of various Stocks for the Orange, with notes- 

 on mat di goma, and the mutual influence of Stock and Scion. — B. N.
