(■banged conditions, but the position as it appears to-day h explained 

 b,\' Dr. Juritz, and should be studied by farmers who are using, or 

 who are contemplating the use of, the fertilizer. In so far as the sale 

 of basic slag in the Union is concerned, there was a regulation to 

 the eifect that it must contain at least 12 per cent, of ])hosphoric 

 oxide soluble in citric acid. Owing to war conditions this percent- 

 age was reduced, as a temporary measure, to 10 per cent., but in view 

 of the present position, this lower percentage has now been fixed by 

 the Government, so that in future (or until such time as it may be 

 found advisable to make other provisions) the minimum phosphoric 

 oxide content allowed in the sale of basic slag will be 10 per cent.

Export of Cotton: Assistance to the Industry. 



Ill our last^ issue we announced that the Union-Castle Steamship 

 Company had reduced the freight rate for cotton to 35s. per ton of 

 40 cubic feet. Further assistance has since been rendered the 

 industry by the steamship lines reducing the rate of freight on 

 cotton seed'. Prom Union ports and Delagoa Bay to the usual direct 

 ports of discharge in the United Kingdom the rate is now 45s. 

 (formerly 60s.) per ton of 2240 lb., with the usual shipping charge 

 of 2s. 6d. per ton from Delagoa Bay in addition. At the same 

 time the Eailway Administration has agreed to convey cotton seed 

 in 11-ton lots when consigned for export oversea at Tariff No. 8 

 instead of Tariff No. 7.
