"aSningtOn.-haVe you an Ideal In
the absolute In hopelessness?
Well, let it be said that the house In
{ which you live Is comparatively new
built within the last IT years. The
ground on which 1t stands was orig
inally woodland. In the summer of
19O2 all the trees Whereabouts were full
or l7-year locusts. Eggs were dep0s-
tied In the branches, the larvae came
out, dropped lightly to the ground, and
dug in. The long period of subter-
ranean existence Is almost ended. In
May the insects will start toward the
light and air-and will come in con-
| tact with the concrete floor Of your
cellar! There may be another situa-
ton as hopeless, but certainly none
| more so.
That clearing up of woodland for
the building of houses and for cultiva.
ton is the principal agency that is max
ing the 17-year locust, whose real
name Is the periodical cicada, a van
fishing species. DR.. Gideon B. Smith,
one of the earlier scientific observers,
allowed rather a melancholy note to
| creep into his invaluable manuscript
when he wrote that future generations,
| If they read his writings at all, would
shake their heads and think of him as
| romancer.
Being Slowly Exterminated.
In the same note, also, G. L. Mariatt,
nf }I,n lot
ers, writes In his bulletin, ITO the
lover of nature there is something re-
| grettable in this slow determination of
an insect which presents, as does the
| periodical cicada, so much that is in
| teresting and anomalous"
Thus, the present-day experts of the
| United States department of agricul-
ture agree with the early observer that
the time will come when there will be
no periodical cicadas left.
That time, however, is a long way
off, There will be multiplied millions
| of them this year and in other years
to come. For many persons the cicada
will be as new sight as 1t was to the
first observers when they came from
Europe to the American forests. Mod
ern writing on the subject is done, of
course, in the light of all the observa
| lions that have been made through
more than 200 years. They lack the
freshness of the writings of men who
the insect had been built up. Those
early writings, therefore, possess an
unusual interest.
Accompanied by Fever.
In 1869 Nathaniel MOreton. who
lived at Cambridge, Mass, wrote "New
England's Memorial" In it he told OF
"a kind of a pestilent fever" that had
prevailed In 1888 and carried of
many of the whites and Indians in and
near Plymouth"

Gus company of flies, which were like

ground, and did eat up the green

ers."
The old gentleman Is to be excused
for believing that the cicadas odd eat
up the green things" The appearance
Of the dead and withered branches
doubtless was such as to justify such a
conclusion. One "T. NJ" supposed to
be Thomas Matthews, son Of Samuel
Matthews, governor Of Virginia, who
observed the cicadas In 1875, fell into
| the same error.
For nearly 800 years, then, the writ
ten record of the cicada has been
piling up, undergoing corrections now
and then, receiving new discoveries
from time to time. AS nearly as can
be judged 1t Is complete now. The
| latest addition Is a circular, 1.-The Sew
| enteen-Yea Locust in 1919," by Dixon
Merritt of the office of information
United States department Of agricul'
ture. 1t does not pretend to present
new facts, but 1t gives a succinct his
| tory of the cicada and the protective
| means that can be taken against 1t
The circular will be available to inter
ested persons In the q states where
the periodical cicada will appear this
