Washington. ID. C.-Her name is
Mary. She wrote a nice little note
from Hayerford. Pa, to the bureau OF
entomology at the department OF ag'
rieulture
Il enclose three funny moths l
caught the other day" wrote Mary.
WIN you kindly tell me what they
are?"
Whereupon the bureau OF entomol-
ogy rose from It's several chairs and
began to move In circles. Mary had
found the brown tail moth in Penn
sylyania, where the brown tail never
had been heard of before. A brown
tail moth is as destructive TO elm
trees as a forest fre No one knows
how many millions Of dollars have
been spent In fighting IT,
Got" said the centurlons Of the
bureau. Beat 1t to Pennsylvania
and find out all about this dreadful
thing"
A squad OF entomologists appeared
in Hayerford next morning Other
Dug connpisseurs heard the news and
they went to Haverford. For a week
young men stumbled through its
streets, their eyes fixed on the tops
OF trees. The pockets Of the young
men bulged with butterfly nets and
poison bottles. They hunted, but
could find no moths. At last they
looked up Mary.
Quick" they gasped. Tell us
where you caught the brown tail
months"
oh" said Mary, Il brought them
home with me from Maine"
The bureau of entomology is adding
to our stock Of bug lore every day.
Lately II discovered that the ultravio-
let rays are powerless against the
bacteria which inhabit milk. Every
one knows that X-rays have a deadly
effect upon the human body II they are
applied too often. But the cigarette
worm-which lives In made up tobac-
co-not only is impregnable to the
X-rays, but 1t actually seems to -four
ish in proportion TO the amount OF
X-rays it gets.
Just to prove that the pear tree
blight is caused by an animal or
ganism. the scientists are raising this
bacteria In bottles BY and by they
will raise in the laboratory another
pest to eat this pest up.
/ mhau Ala NTH aIfaIpa
weevil They imported some sort of
bug which for lack of more intellig-
ible name was called the alfalfa
weevil-weevil. Anyhow, it is a weevil
which feeds on the weevil which feeds
on alfalfa. 1t is saving this valuable
crop in some parts Of the west
The oddly of the moment, however,
is the sick nurse Of the hairy vetch.
Vetch is a valuable forage plant, but
it isn't hustler. When it finds soil
that is deficient in nitrogen it just
lies down and dies.
Whereupon the entomoiogists take a
bottle of bugs out to the vetch field
and turn them loose. These bugs
have just one idea in life, apparently.
They hurry to the roots of the Vetch
and begin to feed 1t the nitrogen II
lacks.
Conversation about frogs is not en-.
couraged In the bureau of animal his
tory. Not long ago one of its bright
est young men became enthusiastic
over batarachians. He wouldn't talk
about anything else. He slipped live
ly green frogs into the hands of those
he liked and was invariably shocked
and irritated by the effect He spent
his spare hours IN catching frogs OF
studying frogs or talking about frogs
So they put him under the judicial bell
glass.
This man isn't crazy" said the
judge, after the frog connoisseur had
concluded his defense He is a great
< scientist. But l think that some Of
his accusers are suffering from echoes
in the garrett"
