EXPERIMENT STATION RECORD. 



l)er acre, G.60 and 9.47 ])er cent of sucrose, and 56.58 and 68,13 purity. 

 Group IV is closely allied to group iii. Group v is characterized by 

 parallel narrow cracks or streaks of a brownish color upon the maturer 

 joints of the stalks. Group VI consists of canes with large tonnage and 

 good sugar content. The two varieties of group vii are closely allied. 

 Group viii consists of clean, smooth, green canes, medium stalks rich 

 in sugar. The tonnage is not large. " Sacuri has for two years sur- 

 passed every variety of cane on the station, foreign and domestic, when 

 submitted to polariscopic tests." Caledonia Queen, constituting group 

 IX, is not recommended. Japanese, or Zwinga, constituting group xi, 

 is "extremely hardy and enormously productive under good cultiva- 

 tion, and exceedingly woody, difficult to crush, and low in sugar."' 

 Bamboo has enlarged nodes and prominent eyes. 



Second and third classes (pp. 851, 852). — Of the second class only 

 group II, identical with the common striped cane, and group vi, with 

 large, straight, long jointed, dark-red stalks with faint black stripe^i, 

 high tonnage, and low sugar content have been tested on a large scale. 

 This is also true of all the groups of the third class. 



Varieties originating from hud variation (pp. 841, 842). — Phenomenal 

 stalks of cane, partly white and partly purple, were planted, using on 

 one row entire canes, on another only the white joints, and on another 

 the colored joints. There resulted 4 distinct varieties, diiferent from all 

 others at the station, viz: (1) A white cane, which was named Soniat; 

 (2) a light striped cane, called Nicholls; (3) a light purple cane, named 

 Bird; and (4) a dark striped cane, named Garig. 



Tonnage and composition (pp. 852-859). — Tables give tonnage and com- 

 position of 49 varieties grown as plant cane in 1892, and as first-year 

 stubble cane in 1893, and of 54 varieties grown as plant cane in 1893. 



Windroiving and topping (pp. 862, 868). — The results of experiments 

 in windrowing vs. leaving cane standing, and in topping standing cane, 

 are tabulated, but not discussed. 



Striped, vs. purple cane (pp. 860-871). — The following table gives the 

 results of 174 experiments made at the stations during 4 years (1890-'93) 

 in comparing striped and purple cane under many different conditions:
