The yield of the plots receiving no fertilizer shows that the land 

 was capable of producing a good crop without the aid of manure^ 

 and so it should not be expected that the fertilizers would cause a 

 marked increase of crop. Nevertheless, the increase was quite large 

 in some cases. 



The following brief comments may serve to point out the impor- 

 tant facts indicated b}' the above table : 



(1). The largest increase of crop was produced by the use of sol- 

 uble phosphoric acid, in the case of the dissolved bone black. Ex- 

 perience has shown that this would probabh' be the case for the first 

 year. Will it continue to be the case for several 3'ears? 



(2). The undissolved phosphates, viz: the fine ground bone and 

 fine ground rock, were undoubtedly used by the crop to a consider- 

 able extent, as can be seen by comparing the yield where these fer- 

 tilizers were applied with the yield where the muriate of potash and 

 sulphate of ammonia were used without phosphatic material. 



(3). For the first year's crop the yard manure proved inferior to 

 the best complete commercial fertilizer.
