applied to plots 10, 11, 12, 24, 25, 32, 37, 41 and 45. Muriate of 

 potash was applied to plots 7, 8, 9, 22, 23, 30 and 38. Magnesium- 

 potassium carbonate was applied to plots .13, 14, 15, 26, 33, 39, 43, 47 

 and 48. Bone meal was applied to plots 3, 4, 8, 11, 14. i7, 21, 22, 24, 

 48 and 50. To this should be added plofs 34 to 38, 43 and 47 which 

 were treated with blood and bone. Acid phosphate was applied to plots 

 6, 6, 9, 12, 15, 18, 23, 25, 26, 29, 30, 31, 32, 33, 40 to 47, 49 and 51. 

 The endeavour has been to give to everv plot represented as much 

 ammonia as any other plot received, and the same in re^^ard to fiotash 

 and phcsphoric acid. (Excepting in cases of inco . plele formulae.) 

 In comparinor the above notes the reader will notice th:it the diiFeront 

 forms oi" potash were placed as nearly contiguous ai the circumstances 

 allowed. Therefore, the concln^ions reached in regard to potash in this 

 experiment must be onsidered as being the most satisfactory. The 

 append ad table will give the plots in such a way that they may be 

 compared with one another to better advantage :

EXPLANATION OF THE TABLE. 



The above table shows the composition of the fertilizer applied to 

 each plot and the class to which each plot, belonged in December, 1^98^ 



The plots marked 1st class ^ere better than what oae is accustomed 

 to find in pineapple sections. Plots marked 2nd class would pa«5S for 

 fine. 3rd class good. 4th class indifferent, witii some spiky plants, 

 5th class f)oor, with considerable percerua;^e of spiky plants. 6th class 

 practically w(.^rthless, over 40 per cent, spiky and the rest doing poorly 



[fj CONCLUSIOF, 



Ammonia. — For young pineapple plants growing on spruce pine 

 land which has not been fertilized before, blood and bone furnish the
