NOTES AND COMMENTS. 



Contents of Present Issue. 



The editorial deals with The Maintenance of Soil 

 Productivity. The subject is treated from a broad 

 point of view, in connexion with its relation to the 

 general agi-icultural prosperity, in any given country. 



An interesting note, supplementing the information 

 that has been given already on the New York Sugar 

 Trade Laboratory, appears on page 291. 



The same page gives jiarticulars of some of the 

 exhibits that have been sent from the West Indies to 

 the Canadian exhibitions. 



Page 293 contains an account of several of the more 

 interesting means that are being employed to bring 

 about improvements in agricultural methods in India. 



Two articles appear under the heading Insect 

 Notes, on i)age 298. These treat of the recent Brussels 

 Congress of Entomology', and the connexion between 

 house-flies and disease. 



On page 302, the Fungus Notes contain the first 

 of a few articles on some of the diseases of rubber trees. 



Rubber plants also receive attention, on page 303, 

 in an article which deals with the tapping of Hevea 

 brasiliensis.

Part T. Viil. XI, of the West Indian Bulletin is 

 just being itssued. The first pa})er in this, b}' Mr. F. W. 

 South, B.A., Mycologist to the Departaiient, deals with 

 The Cnntrol of Scale Insects in the West Indies by 

 Means nf Fungoid Parasites. The subject is treated in 

 three p irts, of which the firsD gives a general account 

 of the fungoid parasites of scale insects, while the sec- 

 ond and third deal with the distribution of these in the 

 Lesser Antilles, and throughout the world. The piper 

 is illustrated by line diagrams showing various stages of 

 ihe fungi. The next article is reproduced from the 

 Tiventy Fifth Annucd Report of the Bureau of 

 Animal Industiy, United States Department of Agi-i- 

 culture, and treats of Epizootic Lymphangitis. 



The third paper is entitled A New West Indian 

 Cacao Pod Disease, by Mr. C. K. Bancroft., B.A., and 

 describes a new fungus {CoUetotricIium Cradivickii) 

 which has been found to attack cacao ])()ds in Jamaica. 

 A plate containing reproductions of three blocks, 

 prepai'ed from photographs, series to illustrate this 

 paper. It is followed by annriicle by ilr. H. A. Ballon, 

 M.Sc, Entomologist to the Depinmenr, in which infor- 

 mation is given vvith a view to iissisting in dispelling 

 some of the confusion that exists in regard to the names 

 of scale insects, Mr. Ballou follows this with aiKither 

 paper entitled Notes on Lime Cultivation, dealing 

 with experiments carried out in Montserraf, with the 

 aid of the Montserrat Lime Com])any. 



As has been stated in the Agricidtiiral News, 

 experiments have been commenced at several of the 

 Botanic Stations with a view to ascertaining the effect 

 of planting trees in the West Indies according to the 

 unorthodox methods in vogue at Woburn, and an 

 account is given of the stage to which the trials have 

 attained at several of these stations. This article is 

 illustrated by three plates, which give a means of com- 

 ]iaring the growth of the trees, under the different 

 conditions of planting, in the trials in Dominica, and is 

 followed by an account of a visit to the Guanica Cent- 

 ral Sugir F'actory. Porto Rico, by Mr. J. R. Bovell, 

 I.S.O., Superintendent of Agiiculture, Barbados, and 

 :\Ir. H. A. Bovell, Barbados. 



The two last papers are by Mr. H. A. Tempany, 

 B.Sc, Superintendent of Agriculture for the Leeward 

 Islands; they give an account of Manurial Experiments 

 with Cotton in the Leeward Islands, and of The Root 

 Development of Cotton Plants in Different Soils. The 

 first of these describes the continuation of experiments 

 with cotton in the Leeward Islands, accounts of which 

 have appeared already in the West Indian Bulletin, 

 Vols. VI, p. 247; VII, p. 283; and X, p. 2(i9. 



In relation to other publications of the Department, 

 it may be stated that the annual reports on the 

 Botanic Stations, etc.. in St. Lucia and Tortola have
