4 Anbury ; and the Analysis of Diseased Turnips. 



ing the farm, Mr. Plumbe, the occupier, directed my attention 

 to a field of considerable extent on the slope of a hill. Sur- 

 rounded by a tract of country visibly abounding in limestone- 

 gravel, the field on the slope and top of the hill presented a 

 striking contrast, even to a superficial observer, with the fields at 

 the base of the hill. These were moderately stiff, full of lime- 

 stone-gravel ; and the root-crops on them looked healthy, pro- 

 mising a fair average yield. The elevated field in question, on 

 the contrary, was sandy in the extreme ; apparently contained 

 but little clay, no limestone-gravel whatever, and the turnips on 

 it were affected by Anbury to such an extent as I never witnessed 

 before. There was hardly a sound turnip to be seen, except on 

 two isolated spots, to which I shall refer presently. With this 

 exception, the whole of the roots were so much injured by the 

 disease that it was not considered worth while to send sheep over 

 the field. The young plants came up well, I was informed, looked 

 remarkably strong and healthy up to the time of singling so 

 much so, that a very fine crop was confidently expected. How- 

 ever, soon after, the crop made no progress, and the roots on 

 inspection were found to be all more or less attacked. At the 

 time of my visit they presented a most extraordinary appearance, 

 being forked and twisted into the most fantastical forms, and 

 covered with wart-like excrescences ; exhibiting thus the charac- 

 ters of Anbury in its most malignant form. 



Part of the field was covered with a brownish-coloured sandy 

 soil, part with a red-coloured ferruginous soil. I examined both 

 on the spot, and prepared a well-mixed sample of each, as well 

 as of the subsoil on which the red-coloured soil rested. 



The subsequent chemical analyses of these three soils, dried 

 at 212 Fahrenheit, yielded the following general results : 



100-00 100-00 100-00 



No. 1 was taken from the top of the hill, where the turnips 

 were most affected by Anbury. 



No. 2 was a red-coloured soil from the slope of the hill, where 

 the turnips were likewise much diseased. 



No. 3 is a deep red-coloured ferruginous subsoil on which 

 No. 2 rests.
