Cultivating Sugar Canes , 247 
thoufand gallons of juice, and exactly the fame quantity 
in a piece which had been planted fifteen months. 
If any body fhould chance to repeat this experiment, 
they fhould be careful to chufe the fame kind _ of 
foil, the fame expofition, and the fame time of year. The 
juice of the piece which was ten months old was a little 
greeniih, that of the piece of fifteen months was exceed- 
ing brown. The four thoufand gallons of juice from 
each of the pieces gave me the fame quantity of very 
fine fugar, which proves that each joint of canes fup- 
pofed to be nine months old contains juft as much fugar 
as each joint of a cane to be fifteen months old. 
It likewife proves, that all the joints, whofe leaves 
have dried and are fallen off, have acquired that matu- 
rity which I call abfolute. 
It 
me donner quatre mille galons de vefou ou jus, et la meme quantite dans une 
piece a^ee de 1 5 mois (fi Ton v ouloi t reiterer la meme experience il faudroit 
ehoilir dans les deux pieces a peu pres la meme qualite des terre et la meme expo- 
fition comme on choifirait le meme terns) le vefou de la piece agee des id 
mois etoit un peu verdatre,. celuy de la piece de 15 mois eroit fort brun; les 
4000 galons de vefou de Tune et de Fautre piece m’ont donne la meme quantite 
de tres beau fuere. Ce qui prouve que chaque nceud de Cannes pretendiies de 
dix mois contient autant de lucre que chaque uoeud des Cannes pretendiies de 
quinze. 
Ctia prouve aufli que tous les noeuds dont les feuilles font deffechees et 
tombees ont acquis cette maturite que j’^ppelle abioliie.
