Plat No. S3 (Sterling, Eans., Plat No. 14 of 1888.) Derived from the best single 

 cane selected from Calumet Plat No. 13, 1890. Juice analysis of this cane, serial No. 

 254, 1890, cut on its one hundred and thirty-sixth day: Sucrose, 15.35; purity, 7G.02. 

 Best single stalk of derivato plat, serial No. 371, 1891, cut on its one hundred and 

 fifty-eighth day : Sucrose, 16.25; purity, 79.02; glucose, 1.50; nonsugars, 2.80. Many 

 (reverting?) canes in this plat and in Plat No. 24, same variety, were noted as ap- 

 proaching the "gooseneck" form in varying degrees. Not a variety worth further 

 experiment here. 



Plat No. 39 (Collier's, Sterling, Kans., lot No. 1 of 1890}. Derived from the best of 

 two single heads grown at Sterling in 1890, and received from Mr. A. A. Denton. 

 Juice analysis of parent cane, serial No. 9170, 1890: Sucrose, 17.89; purity, 82.03. 

 Best single stalk of derivate plat, serial No. 324, 1891, cut on its one hundred and 

 fifty-sixth day : Sucrose, 20.55 ; purity, 82.10; glucose, .51; nousugars, 3. i'7 Panicles 

 all fully out by the one hundred and thirteenth day; seed hardening by the one hun- 

 dred and forty-fifth. A thin stand of unevenly developed canes. The same tendency 

 to barrenness of panicles as remarked of other plats of this variety. 



SPECIAL PLATS CROSSES OR VARIATIONS. 



Plats Nos. 25 to 37, inclusive, were planted from certain specially noted and large 

 canes found among the various plats grown in 1890, and selected chiefly on account 

 of size. A little analytical work was done on all of these special plats, but only one 

 of them was found at all promising. 



Plat No. %7 (from a plat of Red Libcriari). Derived from a large cane selected from 

 Calumet plat, No. 5 A, 1890. The parent cane was noted for very great size and late 

 maturity, and was in appearance totally unlike any variety tried on this plantation. 

 On the one hundred and eighty-sixth day, when cut and analyzed, this cane was 15 

 feet in total length and something over 1 inch in diameter at the largest internode. 

 Juice analysis, serial No. 706, 1890 : Sucrose, 9.25 ; purity, 65.84 ; glucose, 1.24 ; nonsug- 

 ars, 3.56. Best single stalk of derivate plat, serial No. 583, 1891, cut on its one hundred 

 and seventy-ninth day: Sucrose, 11.15; purity, 64.46; glucose, 2.33; nonsugars, 3.82. 

 Less than a dozen seeds were secured from the parent cane, nine of which came up, 

 and by profused tillering gave an excellent stand. Panicles appearing at irregular 

 intervals, the first being observed on the one hundred and thirtieth day. On the 

 one hundred and forty-eighth day, nineteen canes were growing in this plat; on the 

 one hundred and fifty-fifth day seed began to mature, the tillers being indistin- 

 guishable from the seedlings, and all were of as remarkably large size as the original 

 1890 cane. 



Excepting Plat No. 27, all the special plats of the first planting were characterized 

 by great diversity of form and type among the canes produced, and were noted 

 rather for size than for any value as sugar-producing varieties. Enough analytical 

 work was performed on them to sufficiently demonstrate their unfitness for further 

 propagation. But No. 27 showed the marks of a stable variety, and its large canes 

 and their yield of juice seem worth an attempt towards raising its chemical stand- 

 ard and shortening its period of growth by future selection. 



LARGE PLATS FOR AVERAGE SAMPLES. 



Plat A (Early Orange}. Planted with mixed selected seed from several canes grown 

 in Calumet Plat B, 1890. A single long row in the midst of a field of Red Liberian 

 (forage crop) was used for this crop, and afterwards intentionally received the same 

 lack of attention and cultivation. Drought led to the abandonment of this plat, 

 scarcely any stand being secured by the one hundred and eighteenth day, and a second 

 planting with the remaining portion of the same seed was made elsewhere. Later rains 

 eo helped matters that a return was made to the original plat and analytical work 

 regularly done upon the canes. Juice analysis of an average sample from the parent
