TUESDAY P. M. SESSION

President Bishop, on calling the
meeting of the planters association
to order yesterday afternoon, asked
for remarks on the report Of the com.
mittee on cultivation and fertilization
on unirrigated plantations. Perhaps
the subject had been made thread
bare by the various authors of pa
pers, yet some member might have
something new TO offer. Mr.. Hind,
he remarked amidst laughter, might
explain what he meant, in the con-
clusion of his letter, by saying the
Hilo planters. on account Of the rain
fall In that district, had nothing to
do but watch the cane groW.
Noel DEER on discussion on the
previous report offering, was called
on 70 read hts report entitled Annual
SYnopsis Of NH Data, - the ex-
pertinent station series
Mr.. Gartley thought the authors es-
innate on the basis Of efficiency a

going wrong would greatly upset the

Garfiey did not think so, as the
col ton was taken into account in
er Rting.
III peerr, answering Mr.. NOR, said
the same formula, as between mill
and boiling house, was used in all
mills Included IN the calculations.
James Glib Inquired If an Increase
of hydraulic pressure had anything to
do with It. He had heard of a case
where the weight was reduced IN the
last mill. &.
Mr.. Gartley replied with technical
information. his conclusion being that
where rs per cent was obtained In the
first rollers the extraction would be
good. He thought 1t exceptional If the
Kraiewski crusher of the old style ex.
tracted more than 3S per cent.
John Hind had found at Hawaii that
increase OF rolls was an improvement
over the Krajewski crusher.
Mr. DEER among other things said
a difficulty was that the hard outer
rind was not divided fine enough for
penetration OF the water. The 1S-
roller mill at Eva, for this reason,
had not yielded the extraction calcu-
lated.
Experience Of Old. Timers
Mr.. Gartley described a growing
of rollers which Increased the tear
ing action. A diamond roller at Pa
hala had produced good results. Kra-
jewski rollers wore hollow at the mid
die, but the makers were now turn
Ing out an improved type,
Mr. Weinzheimer used the KFajew-
ski at Pioneer mill although not OBJ
tanning as good results as reported
from other mills with diamond rollers.
Secretary w o. Smith related the
experience of some of the old-time
planters, which went to indicate that
results were affected by the condition
of the cane at different times during
the season MT. DEER admitted that
cane conditions were factor. and Mr..
Gartley mentioned certain cane vari.
cites that yielded easier extraction
than others. &c.. 5
w. w. Goodale, while conceding
that unripe and oyefTipe cane were
not equally responsive to extraction,
believed that If all the mill conditions

cause little difference in degree of ex-
traction obtainable Cane containing
II per cent of sucrose could be made
to yield an extraction proportionate
to that gained from cane having Is or
Is per cent of sucrose. He gave facts
of experiments made the past year
which showed that varying roll pres
sures caused but little variation in re-
suits. Constant watching Of every
process only left incomprehensible
problems.
George r. Ewart said that about IS
years ago planters reckoned that
March was the best month for taking
off plant cane.
Coed Record MT Hakalau
John A. Scott offered an explanation
of the good record made at Hakalau.
he having adopted a mode from there
at Hilo mill Having ascertained that
Hakalau had its return bars set. very
much higher than those at Hilo,, he
had changed the setting of his return
bars accordingly. He had been get
ting an extraction of SO to "a per
cent The mill was shut down and
new return bars we're fitted to the
rollers exactly the same as at Ha.
kalau, with the result that the extrac-
ton came up to 95 per cent and over.
Later, during his absence, his engi.
neer changed the setting back to the
old way and the extraction dropped to
"a per cent. Last year he took in Q
new force of engineers, promoting q
young man who had been night en-
gineer to the position of chief. They
saw that the mill was fitted with the
