SHADE TREES OF
FARGO IN DANGER
coTToNY SCALE APPEARING ON
THE SHADE TREES OF FARGO
PROFESSOR soLLEY GIVES ADJ
VICE REGARDING pEsrRuc.
TON OF THE SCALE.

The appearance of a soft, snow-like
insect on the trees of Fargo during
the last few days has caused many
property owners great deal of worry
regarding the future of their shade
trees.
In speaking with a representative
OF The Forum this afternoon Prof H.
L. Bolley OF the A. c. stated that the
soft, white worm that was seen on
the trees Of the city was the cottony
scale and that there was a cottony
scale for almost every kind Of tree.
Professor Bolley said: "The white
snowy thing that one sees on the trees
is the old insect, being the female ami
NAL. Inside this are hundreds of little
eggs and when they are Matched out
they will be so small that one can
hardly perceive them with the naked
eye. They are especially noticeable on
the trees in dry weather.
"one can get rid of the cottony scale
by using the ordinary yard hose. The
finest stream that can be secured from
the hose should be turned on the tree
where the scale is. This stream will
then be Of some force and will knock
OFF the scale onto the ground. II will
be impossible for them to climb back"
Professor Bolley advised the turning
OF the stream onto the trees every
night and every morning. In this way
the scale will soon be gotten rid OF
in very satisfactory manner.
Trouble at Forks.
The following is from The Grand
Forks Herald To The Editor: THE
insect, which may be seen at this sea-
son, doing great destruction among
trees, Is caterpillar, and during re.
cent years has done much damage to
many different varieties of trees, such
as box-elder; eIms. cottonwood or
green ash. BY careful examination
you will see many of the trees affected
at this time. Large punches OF eggs
may be seen, which, in the course OF a
few days will hatch out into little
caterpillars and in very short period
Of time, will devour the foliage and
spread from one tree to another. The
consequence will be that the trees win
die IL not attended to.
II this trouble is allowed to run its
course, and the trees are not sprayed.
the insects will hatch second time. I
would also suggest, that anyone hay
ing trees, look them over and ex-
anime them carefully. Then spray
with a solution of arsenate OF lead
two pounds to fifty gallons OF water.
as soon as they made their appear
ance, and as often thereafter as ia
necessary. have found this to be
very effective.
/ may further state this spraying
will make the trees white, but only
for a day or so. Respectfully,
John Macdonald,
Supt. Public Parks.
The above communication from Sd.
perintendent Macdonald, Of the park
system, yesterday, called attention to
the fact that especially in the south
ends. the box elder trees are literally
covered with little worm nests. These
nests are about the size Of a pea spun
out of white material and full OF hum
dreds OF the little eggs that will breed
an equal number Of little green worms
that grow to the length OF nearly an
inch. Where they are thick, they SIM
ply strip the trees bare Superinten-
dent Macdonald has haa considerable
experience with these pests further
east, but never in this part Of the
country. He says, however, that he
has used the remedy given In the
above communication successfully on
many occasions and it Is UP to the
residents OF Grand Forks to get busy
If the shade trees are to keep their
luxuriant foliage. Bugs, insects and
worms galore is one OF the prices to be
paid for a season with abundant rains
followed by fine warm weather.
Many residents have asked for IN
formation regarding these little white
insect nests that have made their APP
pearance In the box elders and now
that the information Is at hand, all
citizens should examine their trees and
act at once. Spraying now means that
the worms viii be literally nipped III
the bud or rather On the twig and an
ticipated damage will not materiaiize.
Neglect to act now viii mean much
harder fight against the pests Iii d
