SUMMARY 



The cane grew well in spite of late planting and long soaking 

 of the seed. The per cent of harvestable suckers varied from 

 0, where the cane was thickest, to 81 in the plot where the plants 

 were farthest apart. These low figures are doubtless due to 

 late planting, as neighboring estates where cane is grown with 

 even less space between the tops often produce from 200 to 300 

 per cent of suckers. 



The sugar content of original plants has been shown 3 to ex- 

 ceed that of the suckers, and a correct balance between originals 

 and suckers will give, therefore, a maximum sugar output per 

 hectare. 



The use of fertilizer was very beneficial on the soils used in 

 these experiments, and increased the yield of stripped cane to a 

 marked extent. Many fields are in a similar exhausted state so 

 far as sugar cane is concerned, and would doubtless give corre- 

 sponding returns for capital spent in suitable fertilizer. 



The results obtained in the preceding experiments clearly show 

 the necessity of artificially replacing the food elements which 

 long-continued planting has removed from many sugar hacien- 

 das, and indicate the increased output that may be expected from 

 such treatment.
