this proposed process In this report
lii was shown That from the scientific
standpoint Mr.. lsuitcllc'a process IA
entirely sound and thnt following n GER
tain preliminary treatment Of the cane
Juice the Sien1n process, aa employed
IN beet sugar factories can be made TO
increase the availability Of cane sugar
cit was stated, however, that The
commercial value OF the proposed
method could be determined only by n
practical large scale test, since small
laboratory experiments and theoretical
calculations were not sufficient for this
purpose. On September 81 / was
authorized by the trustees Of the asso-
citation TO erect an experimental plant
capable OF turning out about two tons
Of supar per day and to conduct
thorough trial Of the recalled Battelle
process. The pinns for snis installation
are now being prepared and the process
in question will be subjected to pfac
tical test during the 1912 grinding
season"
Every plantation man is directly in
terested in this new process and the
larger experiments to be conducted this
season will be watched with the great
est attention.
Improved Fertilization.
But there was another topic covered
at length in the report of Director
Eckart which, If anything, aroused still
more interest, and that was new fer
tilizer, the results Of which have been
so surprising that il is probable this
l,o oil tho
Territory on every plantation. In his
report on this subject Director Eckart
said:
GAS result of the Investigations
conducted by the experiment station in
connection with the subject of fertil-
izaton, a radical change was effected
in the average quantities of nitrog IN
and potash applied per acre for the
1911 crop of the Islands, the nitrogen
having been increased over that used
for previous crops and the potash de-
) creased. Between $4,000 and 10000
acres harvested during the 1911 season
q received mixed fertilizer which CON
formed with the station recommends
tions, based upon the new principles
brought out by the series of field ex-
] periments.
"In addition to this area which re
ceived a mixed fertilizer that con
formed with the improved formula, q
large proportion of the lands cropped
during the season now closing received
/. an increased amount of nitrogen in the
J. form of special spring dressings OF
!. nitrate of soda or of sulphate of am
+, mOnia.
"Altogether sixteen field exper
!. ments, bearing upon the great relative
Importance of nitrogen in sugar cam
! fertilization, have been conducted OF
I plantations Of the association during
! the last six years. Some of these ex
!. periments formed the basis for tn
I Recommendations made by the statio
!. in 1909 for the 1911 crop while other
I were completed subsequent thereto an
served to confirm the conclusions al
? ready expressed in the circular letter
: which had been addressed to the planta
: tion managers on this important sub
: jeet. These sixteen experiments EN-
81 braced those tests which were con
= cerned with notifications of the Gus
. tomary formula, together with thos
: which dealt with the effects Of regula
S' heterogeneous dressings, where the latte
y had not previously been applied.

l. suits from all of these experiments

T. an acre to over ten acres, pointe,

patent that the extended application O

O. conviction therefore, notwithstandin
d, certain opposing views, that the III
rs. precedented yield of the 1911 crop fc
the islands was due principally to thi
q change in fertilizer practice. To gail
Is, say this result, which was expected an

Highest Record Yield.
IA In the discussion which followed I'll
le, reading of his report Mr.. Eckart state
nd that this new fertilizer was such
fe success that the yield of the cane Gro
nj, for 1911 per acre was the highest O
an record per acre for any year In n
Ia history Of the sugar industry, new
u. mind how far one went back in Il
