It will thus be seen tliat the matter is being thoroughly' dealt 

 with, and, while the investigations are expected to run over a number 

 of years, it is hoped that as a result we will thereafter be able to deal 

 effectively with nagana as well as other trypanosome diseases, and so 

 achieve yet another success in our campaign against the stock diseases 

 found in South Africa. 



Supplies of Wheat and Rye available for Importing 

 Countries. 



A recent publication by the International Institute of Agricul- 

 ture, Rome, furnishes data of very great interest as to the quantities of 

 wheat and rye which importing countries may obtain during the 

 season from 1st August, 1920, to 31st July, 1921. 



On the basis of data now available, and of forecasts of an average 

 yield from the grooving crops in Argentina and Australia, it is 

 estimated that Bulgaria, the Serb-Croat-Slovene State, Canada, the 

 United States, British India, Argentina, and Australia should be able 

 to export during the season 17.5 million tons (metric tons of 2,200 lb.) 

 of wheat and 800,000 tons of rye, making a total of 18.3 million tons 

 of breadstuffs. Taking into account the fact tliat the quantity afloat 

 on 1st August, 1920, was very large, the aggregate quantities at disposal 

 of im])0]'tiiig countries are estimated at 18.6 million tons of wheat and 

 900,000 tons of rye; the complete total is therefore 19.5 million metric 

 tons, against a quantity amounting to 18.5 millio,' tons of wheat and 

 rye, forming the actual receipts of importing countries during last 

 season. 



On the other hand, the total production of the two cereals in the 

 importing countries comes out very nearly the same as it was last year 

 (33.2 million tons against 33.5 million). 



It follows that overseas requirements should not be much greater 

 than last year's, while potentially about 1 million tons more than 

 they imported last season will be at the disposal of importing countries. 



But there is no positive assurance that the potential exportable 

 surplus will in its entirety reach the countries that may need it, 

 inasmuch as it is not certain that India will export all its apparent 

 surplus, wjjilo present expectations regarding harvests of x\rgentina 

 and Australia may need to be modified. Prudence dictates absten- 

 tion from undue optimism in view of these uncertain factors of the 

 situation. 



Wine Show at Capetown, 1920. 



Commenting on the Wine Show held by the Western Province 

 Agricultural Society at Capetown last year, Mr. S. W. van Niekerk, 

 the Government Yiticulturist, says that in the number of entries the 

 show was a success as compared with previous years, entries amount- 

 ing to 179, as against 30 in 1919. The quality generally was good, 

 although it was noticeable that, on the whole, the condition of the 

 wines was not up to the standard of previous years. This may be 

 due to the fact that the samples had to be forwarded in August 

 instead of towards the end of October, as in previous years. 



The increase in entries was due not to the earlier show date, but 

 to the appointment of a wine expert by the AVynboere Ko-operatiewe 

 Vereeniging van Zuid-Afrika, in the person of Mr. F. Myburgh, who
