Feeding stuffs in most cases advanced in value from Novem- 

 ber to December, the chief increase being recorded for bran, 

 which in December was at about double its pre-war price. 

 Fertilisers showed little alteration, with the exception of basic 

 slag, which was considerably cheaper; superphosphate showed 

 a slight decline, and sulphate of ammonia an equally slight rise.

 those varieties of potatoes which after careful trial had been ap-
