cessful crops of H 100 cane and a wido
range of exhibits and working expert
ments divided interest during the day.
Leaving the city in fourteen automo.
biies, the party went first to the upper
lands of Oahu Sugar Company TO see
II demonstration of caterpiller tractors,
Here three Holt tractors performed
evolutions for the association members
that were highly interesting and in
Etructive. A foTty.f five horsepower Holt
tractor hauling q Spalding deep tiller
plOw was the center Of interest. The
caterpiller, unlike the usual tractor has
no front or steering wheel, depending
on it's two caterpiller wheels with which
it crosses bitches, mounds, roads and
fields with equal ease. With but the two
wheels, the tractor can turn in its own
length.
Flows Wide Strip
With three deep-tiller plows connect
ed in n series, the tractor plowed u 500
foot strip about five feet in width in
twelve minutes. The burrows averaged
thirteen inches straight depth and be-
tween twelve and fifteen inches on the
level.
An eighteen horsepower tractor gave
n practical demonstration of its value
on a plantation when it hauled heavy
motor truck loaded with machinery
that had been stalled, over muddy roads
and through the fields.
Probably the most important demon
stration of the day was the view of
fields of II 100 cane grown on Eva
plantation. Manager Renton took his
guests through fields Of this new varie-
ty that astonished some of the man.
ayers A few years ago HI 100 was an
experimental variety. Yesterday Mr..
Renton showed to the planters that il
was not only successful but that it faI
Outranked almost any other variety OF
cane.
Eva Cane Wonderful"
Wonderful" was the term repeat
eddy used by the members of the as
ISOLATION as they viewed the long, thick
full .jOinted canes of HOO that are
growing on Eva.
At the makai side of Eva mill Mr..
Rcnton showed his guests a fine full

in October, 1918. The planters thought
this was the best that had even been
done with H.lO9 Then Mr.. Renton
sprung his surprise. Taking his visit
ors to the other side of the mill he
opened to view u field of the new vari-
ETY. that has been planted in August,
1915, and was even better than 1.-the

From Eva, the party of planters
then went to Waipio where they were
the guests of the experiment station
staff at the Waipio sub-station. AZ
'er lunch, picnic style, under the
vrees, the managers were shown score
If interesting and instructive exhibits
and demonstrations that may mean
much to the sugar industry of Hawaii.
Alcohol From Molasses
Manufacture of alcohol from final
molasses,, use of this alcohol to run an
ordinary gas engine, feeding cattle on
eane-top ensilago and molasses, and an
exhibit of the stages of a simple meth
cd for planters to grow their own seed
lings were the four main working eH-
periments that attracted the most at
tention. General exhibits of cane vari-
cites, insect collections, fungus dis;
eases, fertiliMng materials, irrigation
methods, legumPs and information
charts we're housed in a large tent. .'',
The alcohol manufacture was IN
charge of P. S. Burgess, station chem
list, and F. r. Werthmueller, George
Hutchinson and J. 7. M0ir Jr., assist
ants. Mr.. NOR operated the gasoline
engine with alcohol from mOlasses as
fuel explaining to the planters that
the only adjustment necessary was on
the valves to allow higher compression
and less air. The engine operated a
cane-chopping machine and a small mill
used by the station for experimental
juices. ...,..,l f., IT.,
