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 : —

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. 
In this subsoil, it will be noticed, there is a great deal of oxide 
of iron, a constituent which is likewise more abundant in No. 2 
than in No. 1. 
The amount of lime in all three is very trifling : in the surface 
soils, especially, it is totally inadequate to meet the requirements 
of a crop of turnips. We cannot doubt, therefore, that the de- 
ficiency of lime in these soils has been the principal cause of the 
failure of the root-crop on this field. 
That lime might have been applied to this field with great 
success will appear from the following interesting circumstance 
with which I became acquainted on my visit to this farm. When 
walking over the field, Mr. Plumbe directed my attention to an 
isolated spot, not many square yards in extent. On this spot the 
turnips, though by no means large, were nearly all sound. On 
stooping down and examining the soil, I picked up some bits of
