111 1885 comparative experiments were made with native Amber seed, 

 Amber seed from Prof. W. A. Henry, and native Orange seed. 

 The percentages of sucrose in the three kinds of canes were as follows: 1 



Sixteen plots all fertilized save two were planted in Early Amber and 

 the following data were obtained : 2 



Mean sucrose in canes percent.. 9.37 



Mean sucrose in juice do 10.30 



Average weight sugar per acre pounds . . 2, 372 



Another set of experiments was made at Rio Grande with the co- 

 operation of Mr. George C. Potts and Mr. H. A. Hughes. The follow- 

 ing data were obtained. Early Orange cane, sixteen plots, all fertilized 

 but one : 3 



Mean percentage sucrose in juice 9. 88 



Total weight sugar per acre pounds . . 2, 508 



In reviewing the operations of the Bio Grande factory for the past 

 five years, Professor Cook says : 4 



The records of this plantation for the past five years show that upon the average 

 7.7 tons of unstripped and untopped cane only Lave been grown per acre, while the 

 average yield of merchantable sugar per ton of cane has not exceeded 40 pounds. 



To compete successfully with other sources of cane sugar, therefore, the average 

 tonnage of good cane per acre should bo at least doubled, while the quantity of mer- 

 chantable sugar secured per acre should be increased many fold. 



In 188G the experiments at Rio Grande were continued. Sixteen 

 plots all fertilized but one were planted in Early Orange Cane. The fol- 

 lowing data were obtained : 6 



Cane (leaves and seed) per acre pounds.. 13,383 



Clean cane per acre do 10, 448 



Sucrose in clean cane per cent.. 7.95 



Total weight sugar per acre pounds . . 905 



Professor Cook makes the following remarks on the results of the 

 season : 6 



Three years ago it was clearly seen that the Rio Grande Company failed to secure 

 one-balf of the total amount of sugar present in its sorghum crops, and since that 

 time all energies have been directed toward the substitution of diffusion for milling.
