canes more per acre. The fields used were all manured 

 with nitrogen and potash in proportions somewhat in 

 excess of the manurial requirements of the canes, whilst 

 some plots received nothing in addition, others, super- 

 phosphate of lime in proportions averaging 75,112, and 

 150 lbs. of " soluble phosphates" per acre, respeflively, 

 and the remainder insoluble phosphates (mineral and 

 precipitated phosphates) in quantities equivalent in 

 money value to the lowest and highest dressings of 

 superphosphate used. The following table gives the 

 average result of these experiments : — 



The above results show that a great increase was 

 produced in the yields of canes and of sugar by the use of 

 superphosphate of lime in moderate quantity (equivalent 

 to about 250 lbs. per acre of an ordinary 30 per cent, 

 superphosphate) ; and that the use of larger amounts was
