Part of the cane to plant (pp. 366-368). — In 1800 selected stalks of 

 cane were cut into two and three parts, that is tops, middles, and 

 butts, and used for seed, and the observations were extendol to the 

 stubble in the followin": year. The results are tabulated for ea<h 

 year. "It is apparent that the part of the cane used for seed has little 

 or no effect on the stubble. The effect se^ms to be entirely with the 

 first year."' 



Xiimber ofstnlks to pbint (pp. 3n.'-v-;37'J). — In l.S9(» plats were i)lanted 

 with from 1 to 4 stalks, both cut and uncut, and in 1891 the observa- 

 tions were extended to th<' stnbl»l«'. The results of the 2 years' trial 

 are tabulated. Fii is'.io the indications were " that cuttinjj cane should 

 be avoided as far as possible, and the knife used only to secure lnui- 

 zontal ]>osition for tlic cane.'' The stubl>le showed in ISOl very little 

 effect from the cutting. 



Tho difference ia the " cut " and '' unrnt" experiments in 1890 wa« 13.68 tons per 

 acre ; in 1891 it was only 1.08, showinjj that evil efTects of the knife had been nearly. 

 if not entirely, overcome in the stiilihle. Tlie continuance of these exitfrinients 

 emphasizes the snjjjjcstions of last year, viz, that one i;ood, sound cane with a lap,
