Varieties of sugar cane, W. <J. Stubbs {Louisiana Sta. BnJ. 2G, M 

 ser., pp. do(j-t>71). 



Synopsis. — Description of 20 new seedling viirieties received from the Roj-al Agricul- 

 tural Society of British Guiana; aclassilicationof the A'arieties grown at the sta- 

 tion; tables giving composition and tonnage of the varieties grown on afield 

 scale and on experiment plats for 1892 and 1893; and a comparison of the com- 

 mon striped and imrple varieties by means of tabulated data and general notes. 

 The striped cane gave a slightly larger tonnage and larger stalks; the purple 

 cane showed a stronger reproductive power and a higher content of liber and 

 solids-not-sugar. In all other respects, including sucrose content, they agreed 

 closely.

Ribbon. 

 Group II. — Ped Ribbon, Mexican Strijied, 



Batavian Striped, [Louisiana] Striped. 

 Group III. — Tsimbic, Ysaquia, Vituaha- 



ula, Home. 



Group IV. — Ainakea, Kainio, Ahilolo 



(light striped).

First class (pp. 839, 840, 843-847).— The varieties of group i in 1893 

 and 1893 averaged, respectively, 38.25 and 3G.93 tons per acre, 8.42 and 

 10.30 per cent of sucrose, and 65.98 and 80.09 purity. " By comparing 

 both tonnage and sugar content with our home canes ... we find 

 these canes fully the eqnal of our pnrple or striped varieties." 



Analyses and tonnage of 3 of these varieties grown in 1892 as 

 lilant cane and in 1893 as first-year stubble are tabulated, as also the 

 composition and tonnage of Tibboo Merd, Marabal, Pupuha, and 

 Batavian Striped when treated with different fertilizers. The members 

 of group II are identical. They averaged in 1892 and 1893, respec- 

 tively, 39.75 and 38.41 tons per acre, 8.47 and 8.97 per cent of sucrose, 

 and 02.88 and 64.21 purity. "They are slowly becoming acclimated, 

 but are as yet unworthy of extensive cultivation." The members of 

 group III are identical. They germinate slowly, "sucker" and "rat- 

 toon " badly, and hence make a defective stand and low tonnage. They 

 averaged in 1892 and 1893, respectively, 38.32 and 29.79 tons of cane
