superphosphate .J 
This experiment was conducted mfiinly for tlie purpose of 
seeing whether the free acid in mineral sitperphosphates had, as 
asserted in some quarters, an injurious effect on the swede crop, 
in the case of land (as here) somewhat deficient in lime, and 
whether the use of bone-flour, to neutralise its action, would 
prevent any evil effects. The first year (1886) the addition of 
bone-flour seemed to produce at Whitlingham a striking influence ; 
but there was very little, if any, confirmation of this in subse- 
quent experiments, and the results now recorded, and iu which 
exceptionally acid manures were purposely used, may be taken 
as abundantly showing that practically no injury has been done 
by the acid superphosphate, nor any gain obtained by mixing it 
with a little bone-flour.
