disregarded. The crop for the present year has been onions. 

 As has been the case throughout this part of the State, the 

 onion crop suffered from blight. Our yields of sound and 

 merchantable onions are therefore comparatively small. The 

 results are shown in the table : —

The conclusions stated last year were as follows : — 



1. The phosphatic slag evidently furnished phosphoric acid in 

 an exceedingly available form, the yield this year being almost 

 equal to that on the dissolved bone-black. 



2. The Florida soft phosphate is apparently a very inferior 

 material, the phosphoric acid evidently becoming available only 

 with great slowness. 



3. Steamed bone meal appears to be inferior in availability to 

 raw bone meal. 



The results of this year are in most particulars similar. 

 Phosphatic slag, it is true, is exceeded, bj^ a small fraction 

 of a bushel of merchanta"ble onions, by raw bone meal, but 

 it gives a larger total crop. Dissolved bone-black stands 

 relatively lower than last year. Raw bone meal, as last 

 year, is superior to steamed bone meal. The Florida soft
