Smith. -. -
| DR.. Lyon said the only remedy was
TO clean out the dead trees as fast as
possible If they wished to save a
few trees they might do 1t by pruning
back the branches and painting over
the wound. In large forest such
treatment was impraeticable. .@
In reply to a question by Mr.. Smith
IF the disease spread from centers OF
Infection, DIR. Lyon said the infection
was rather scattered One tree may
be attacked at the top, another at the
bottom. Ii the vital parts were first
affected the tree would die quickly.
Mr.. Bishop asked if the disease bad
appeare on the other islans, also II it
was anything like the chestnut tree
disease, to which the lecturer replied
that it had been found on Maui, hut
had not been made on
any of the other islands. He hoped II
would not prove so destructive as the
chestnut tree disease on the mainland.
for which neither federal nor state
authorities had been able to find a
remedy. 1t looked as II the chestnut
groves were doomeds
DIR. Lyon then took up the sub
ject of the stripe disease of sugar
calle, mentioning its discussion by
him in the May and July numbers OF
the Record, also at last meeting. In
thirty-six tests made the loss of cane
in twenty-five cases was 10 per cent,
but he said If all the cane in a block
were tested the loss would be 40 per
cent. They had only taken into &C
count mature sticks, sticks that had
died in infancy not being considered
in calculations Healthy cane from
Eva and Waipahu exposed near in
fected cane had contracted the di-.
sease. The loss in Lahaina cane was
not so great as in yellow Caledonia
and Lellow Tip
In answer to George Davies, he said
he regarded the disease as Infectious.
Six stools out of eighteen healthy
ones had developed the malady in ex-
periments. Tn edisease was very
prevalent in Australia. DIR. Lyon was
applauded az the close Of his adj
dress.
In answer to a question he said the
eucalyptus disease did not attack
cane as did the pineapple disease. 1t
probably never would attack cane. 1t
seemed to attack all kinds of eucalyp-
tus, he said in answer to A. F. Judd.
but the globulus or blue gum more
tina many other.
Mr.. Isenberg wanted to have the
information published. He knew
man who was preparing to plant a
thousand eucalyptus trees.
John A. Scott said the alligator
pears in Hilo had been dying for
years and asked II it was from this
funus.
DIR. Lyon said probably it was from
this one or some other fungus. 1t
attacked mango trees but not nearly
So virulently.
James Glib said they had planted
LIE, 900 eucalyptus on Honolulu plan
tation and he wanted to know If they
should plant any more.
DIR. Lyon said they could safely
neglect the rind disease. In planting
trees this matter must be
taken into consideration. It was not
we'll to plant any tree particularly
tn disease in Dure cul- 1
ture. The eucalyptus might be plant
seases were very selective, individu-
ally they did not attack many kinds
of trees.
John t. Moir asked about the
blight, and was told it was
different fungus. He came back say
