INTERIOR DEPARTMENT
Hteresiaq Leas-The Patent Office has received inter-
esting letters from Messs Vilmorn and Yatemare in
tion to the cultivation of sugar in France The follow
ing letter is from Mr. Louis Vilmorin, of Paris:
Pans April 20, 1857.
The capitalization Of sugar seems to be easily eff
ected whenever the has become perfectly ripe and
the proportion of sugar is constant indication of the
maturity, ii follows that may always be sure of OBJ
tanning good capitalization of such Juice the density Of
which has reached specific gravity of than l0T5
while that presenting weaker density will not be able to
produce, by concentration, satisfactory result
cribe this to the fact that the sugar is preceded in the
juice by gummous substance which to be slower
in its transformation for its proportion absolutely de-
in the ratio that of the sugar increases
Tho uncysallizabe glucose sugar undcrgoes the
notifications is, it is abundant before the
perfect maturity than aerwardbut its action seems less
injurious when at capitalization The guminy substance
checks it in two or while it constitutes obstacle
to its manifestation it afterwards renders it almost i'm
practicable to purify the crystals obtained
This difficulty, however as have said, presents itself
only in the canes not perfectly ripe. AS soon the
juice atains the density of 1885, and over it contains
scarcely anything but crysallzale sugar. the manage
ment of which presents nodifcuty The lime employed
when slightly in excess is not injurious it
TO me- in practice in theory; it may be that little
unavoidable fermentation sets free sufficient quantity
of carbonc acid to destroy the uncrystalible compound
which it forms with the sugar The fact is that the best
crystazations which have obtained showed themselves
in the treatment where, / believe, i mixed too much
lime. ] must confess that | have experimental until
only small scale and it always requires caution
in deriving conclusions from experiments performed in
the laboratory for practical applications At oil events,
however it to me- from these experiments that the
capitalization of the juice of the sorgho does meet
the difficulty wherever the plant has to maturity
