Prohibition of the Export oj Barley from Turkey. — The Board of Trade are in 

 receipt, through the Foreign Office, of information to the effect that the export of 

 barley from any part of the Turkish Empire has been prohibited. {Board of Trade 

 Journal, 28th November, 1907.) 



Growing Mangolds close together. — A system of growing mangolds close together 

 has been adopted with satisfactory results on the sewage farm of the Reigate Corpora- 

 tion. This farm was formerly used for the disposal of crude sewage, but is now only 

 watered by the effluent from sewage beds, worked on the " sprinkler " system. The 

 sewage is purified bacterially to the extent of 99 per cent. , only a small percentage of 

 harmless salts being left in it. The system is to plant the mangolds in double rows 

 about 1 foot apart, with some 16 inches between each lot of double rows. The plants 

 are left very thick, and a small solid root is thus obtained, which finds a ready sale. 

 The crop is. stated to amount to 80 tons per acre.
