the sugar. ‘ The juice of the Imphee,” says Mr. Wray, 
“is naturally more limpid, more free from extractive 
matter, and proportionably easier to defecate.” In cases 
where the Chinese Sugar Cane has been grown on 
swampy land, very large plants have been produced ; 
but the juice contains sometimes several per cent. less of 
crystallizable sugar, than when grown upon dry, warm 
uplands. The canes grown upon warm, dry soils, situ- 
ated so that they can be irrigated at pleasure from a 
neighboring brook, according as the summer heat be- 
comes more or less severe, will give the desired develop- 
ment of stalk, and they will also have much purer juices; 
and hence, as we before observed, the effects of the con- 
stant rains of this season will doubtless be to produce the 
results which have been mentioned by Professor Heuzé 
of Grignon, as resulting from the practice of excessive 
irrigation. 
M. Paul Madinier says, in his little pamphlet, that for 
it are especially suitable light, sandy soils, and calcareous 
soils; but particularly those formed from alluvial depos- 
its. That in nearly every case, especially in Algeria and 
the southern part of France, very excellent results will 
be attained by the employment of irrigation during the 
early stages of its growth, and when it is most rapidly 
developing itself; but that if employed at a later date, 
when it is approaching maturity, it proves deleterious, by 
impeding the elaboration of the saccharine principle, and 
rendering the canes too watery. M. Hardy, the intelli- 
gent director of the Government Nursery in Algeria, 
says that the sorgho flourishes extremely well on soils con- 
taining carbonate of lime, and he advises frequent liming
