The i-esults show clearly the value of manure. Tf the unmanured plots 

 are considered it will he seen that, with the exception of one, the yields are 

 comparatively lo^v, and that, on the whole, they agree fairly well one with 

 the other. The results from tlie manured ]ilots are valuahle, indicating as 

 they do the influence exerted upon the ciop by the ditierent fertilisers. 

 Prominently aljove others stand the results following the ap})lication of 

 superphosphate. The greatest increase in the series was olitained on the 

 plot manured with it alone, and wherever it was used in combination w ith 

 other manures its influence cannot fail to be traced. The results go to show 

 that a supply of soluble phosj)lioric acid is very essential to the tuiiiip crop, 

 owing, not so much to the quantity taken fi'om the soil, but to thi> 

 peculiar inability it appears to lia\-e, in comparison with many other
