The chicken crop of Delaware Is
away ahead of the wheat crop in value.

BY simple rule, the length of the
day and night, any time of the year,
may be ascertained by simply doubling
the time of the suns rising, which will
give the length of the night. and doub-
ling the time of setting will give the
length of the day.
The English government report Of
an investigation into the influenza epi-
demic of the last four years regards the
disease from person to person as
overwhelming. and denies that it
is transported through the atmos-
phere; another warning of the folly Of
unnecessary contact with the sick or
contact without precautions; an emf
nent laryngologist attributes the con-
tagiousness to the breath.
1T is remarkable fact in botany
that no species of flower ever embraces,
in the colors of it's petals, the whole
range of the spectrum. Where there
are yellows and reds there are no blues;
when blue and red occur there are no
yellows, and when we have blues and
yellows there are no reds Tulips come
nearer to covering the whole range OF
the spectrum than any other species.
They can be found ranging through
reds, yell9ws and pprples, but blue
one has never been found.--Popular
Science Monthly.
A considerable quantity Of evidence
has been collected of power in tobacco
to destroy the micro-organism of chol-
era. Herr Wernicke wrapped cultures
in cigars, inoculated them with sterile
dry and moist unsterilized leaves, i'm
mersed them in infusions, and envel-
oped them in tobacco smoke: and in
every case they disappeared in a few
hours, except in five per cent. infu-
sion, when they lived thirtythree days.
Tarsinari found that they were usually
killed after thirty minutes exposure to
tobacco fumes. Immunity from cholera
has been observed among worlimen in
tobacco factories. = Popular Science

One of the deadliest serpents in the
tropics is the fer-de-lance. of which
there are at least eight varieties. These
snakes are of precisely the same color
which will enable them to hide among
the foliage or roots of trees. Sometimes
they are bright yellow and can scarce
ly be distinguished from the bunch Of
bananas within which they lie coiled.
Again, the reptile may be black, or yell
lowish brown, or of any hue resembling
tropical forest mold, old bark or decom-
posing trees The iris of the eye is
orange, with red flashes, and at night
glows like burning coal.
The agricultural crisis" has called
out very interesting review of Italian
agriculture, by Signor Galanti. He
states that the area of land under cul-
tivation in Italy is about 60,OOO,OOt
acres, of which nearly one-fifth is in
wheat, with an annual average yield OF
about eleven bushels per acre: 5000, O0(
acres are devoted to maize. with ar
average yield of seventeen bushels
to the acre; 2,OO0.O0e to leguminou.

comprise the rest of the cereals. Vines
citrus fruits. olives and other fruits re

stock includes 5,OOO.O 900 cattle, 5000, ,OO(
sheep, 100000 goats, 1,sO0,O00 swine

There is a tree which grows in
Madagascar called the Travellers
Tree" which is of the greatest service
to the tired and thirsty travellers in
that tropical climate. This wonderful
tree has no branches, the leaves grow
ing from the trunk and spreading out
like the sections of a fan. These leaves
Of which there are generally not more
than twenty-four on each tree, arc
from six to eight feet in length and
from four to six feet broad. At the
base of each leaf is kind of cup con

water. The natives save themselve.
