the door immediately above the ehain,
the wire, properly bent, is inserted and
the button at the end of the chain is

Fish Froien by New Method.
A novel way to freeze fiBh for ship
ment has been invented in Denmark,
which consists of dipping the fish in
fresh water and then thrusting it into
a vessel containing refrigerated brine.
The fresh-water film around the fish
congeals instantly, preventing the ac
cess of the salt from the brine. So
quickly does this method work that a
live codfish 18 inches long was fro
zen hard enough to be sawn in 15
minutes.
Towerless Windmill Tireless Worker.
A novel windmill manufactured in
Portland, Ore., is supported by a tubu
lar column, instead of the usual tower.
The fans are arranged in two sections,
fonr in each, and are of galvanized
iron, concave, and so adjusted that
they quickly receive the full propell
ing force of the wind, while on the re
turn they are shielded behind a mov
able screen of canvas. The shield is
kept in the correct position by the tall
pitahaya, growing in Lower California,
has been found to eontain valuable
resin in its bark. The plant grows wild,
is from 6 to 12 feet in height and
bears a fruit that is very sweet and
palatable. The resin is found only in
mature plants which have died natur
ally and remained some time in the
sun. The resin is dark in color, with
a smooth surface and hard texture.
When heated it is very adhesive and
could be used to advantage in the man
ufacture of varnishes, electric insulat
ors, and the like.
Effect of Wireless Waves on Birds.
Observations made in sections of the
world where there are many wireless
waves Indicate that birds are disturbed
in a singular way by the wireless
waves. It is stated that gulls are ap
parently the principal sufferers, but
that also large numbers of doves are
in some way prevented from finding
their way home when there are wire
less stations in the line of flight. This
strange phenomenon ib attributed to
some effect of the ether waves not yet
undrstood.
Pasture Fence on Wheels.
A portable pasture fence, made out
of the framework of set pieces of fire
works, is the interesting solution of
fered by an Illinois farmer to the prob
lem of caring for a spirited horse which
runs intself out in a large meadow.
The little pasture is 16 by 20 feet And
the fence is mounted on wheels. One

Remarkable Tunnel Under Mississippi.
The city of St. Louis is safeguard
ing its water supply by a tunnel blasted
out of solid limestone, 64 feet boneatb

intake tunnel is completed it will be
2,766 feet long, 516 feet extending be
neath the land and 2,250 feet under the
river. The tunnel is tubular, 8 feet in
diameter, and will be lined with con
crete when finished. Three shifts
work consecutively, and dynamite is
emloded three times a day. A new
intake tower with a modern arrange

A fruit-bearing cactus, known as the
Wirless Message to Arctic Explorer.
Through Canadian government chan
nels a wireless message was sent to
Donald 8. MacAIillan and his fellow ex
plorers at Etah, Greenland, from the
American Museum of Natural History.
It was a "cheer-up" message of Christ
mas greeting, and while no response
was received or expected, it is believed
the message reached its destination.

SUGAR is a nigwy eoneenirawu iwm,
representing the principal food
elements of Dreaa, nee, poiaioev
and. in fact, of all erains. It repre
sents the starch of these foods, and
Btarch is a very necessary food ma
terial.
Soldiers have been able to endure
long marches on the ready fuel supplied
by sugar, but regardless of this fact
sugar, like all otner concentrated iuuub,
should not be used as a constant ar
ticle of diet, except in very limited
quantities.
One of tne important reason iur
avoiding sugar is that when it is pres
ent in a meal in any appreciable
amount, it checks the secretions of the
digestive juices in the stomach and
thus reduces tne amount or an me ui
irestive fluids, from the stomach down.
This means that there is going to be
sn interference with the digestion of
the meaL If you eat a considerable
amount of sugar with a meal contain
ing, for instance, meat, you prevent the
secretion of sufficient digestive fluid
ts digest the meat: hence the meat will
decompose and poison yon. When sugar
is present in the stomach alone, no di
gestive fluid whatever is secreted, so
when you eat eandy between meals it
is not digested.
Another reason for avoiding sugar is
that it ferments very easily, and in the
nrocess of fermentatio it becomes
more of a poison than a food. Fur
thermore, as the sugar ferments it sets
ut the same process in otner roods,
and thus can change a meal from food
to poison.
Sugar iB frequently the cause, direct
or indirect, of many of our digestive
disturbances. Sugar Is an irritant to
the mucous membranes of both the
stomach and the bowels, and much more
irritating are the substances formed as
the undigested sugar ferments in tne
bowels. In this way sugar may cause
directly catarrh of the stomach and in
testines, and indirectly it may cause
constipation, biliousness, and the "slug
gish liver." Nervousness, rheumatism,
catarrh, too much flesh and too little
flesh are some of the disorders that may
be caused by eating sugar in eonsid
erable amounts.

If your neighbors are not cleanly and
are inclined to harbor flies, speak to
them about it; or notify the Health Officer.
Do not buy your foods where flies are
permitted to thrive.
Do not allow fruits and confections to
become exposed.
Eternal vigilance is the price of rid
dance from this dangerons pcBt
The fly season is now hard upon us.
An ounce of prevention is worth a
pound of enre.
I ERE are a few hints to impress
on school-children:
Keep your faces and hands clean; at
no time put your fingers in your mouth
Unless you have just washed them.
Never touch pencil points nor pens to
your tongue, for you don 't know whose
mouth they were in before.
Insist upon fresh air at all times;
ituffy rooms are a menace to health,
by breeding germs and affecting the
respiratory system. They stunt growth
and stifle study.
Fresh air contributes in a large de
gree to a healthy body; if the body is
healthy and strong it is more capable
of resisting disease.
Avoid the boy or girl who has
'little sore throat," for fear it is diph
theria.
The best germ destroyer is sunshine;
the teacher should not shut it out
The mind is brighter and learning is
easier, if yon have an abundance of
fresh air.
It lies within the province of you
school children to act as instructors to
your parents on sanitary matters. The
prevention of unnecessary sickness can
be effectively accomplished.
The first lesson should be: How to
keep well.
Protect the health of the school child
first, last and all the time.

Three hundred and thirty-two sec

Yakima high-line survey are restored
to entry by an order received by the
North Yakima land office. The re
storation does not include any of the
lands under the Northern Pacific
high-line nor any lands for about half
a mile above the Northern Pacific
survey. This is taken to mean the
government does not expect construc

pect the Northern Pacific project to
be constructed. The latter includes
174,000 acres above the Sunny side

river valleys.
The land restored is open to set

Street-Railway Transfer! Counted by
Weighing.
In many street-railway offices trans
fers are now counted by the simple
and rapid method of weighing. All thee
transfers in the two batches is thus
the main pan of the scales. In place of
the usual weight, a pan containing a
given number of transfers, usually 25,
is slid along the bar for securing a
balance, the relative weight of the
transfers in the two batchese is thus
determined, and from this the number
of transfers in the batch being weighed
is secured.
