Ventilutc5s Add
Much to Comfort
In Hot Weather
BY HILSON MUNSEY

Summertime presents the prob
lem of keeping cool. There are sew
eral ways TO do this including an
air-conditioning system. If that is
out OF the question. adequate ven-
tllation through the windows is
great help. The ordinary double
hung sash has received more atten-
ton in the way of ventilators than
the easement sash but it is also pos
sible 10 install ventilator in this
type of window.
This easement ventilator does not
protrude into the room and so the
drapeS or Venetian blinds are not
interfered with. 1t is, when installed,
flush with the sash and the part
that sticks out is on the outside.
The ventilator measures 1034x2l tx
81 inches. These dimensions run
in order, height, length and depth.
The standard finish is baked on
cream enamel but that won't pre-
vent the enterpriSing householder

Cheap to Operate.
The ventilator is an electrically
operated one that will cost about l
cent every six hours. and that is not
a great outlay considering the COM
fort to be derived from its installa-
ton.
1t is quiet in its operation and has
rheostat volume control. The
filters, with an operating efficiency
of 90 per cent, will last from three
to four months, which nearly covers
the summer period.
They shut out and also shut in
the noise in addition TO the pollen
that is such a Scourge 10 anyone
suffering from hay fever. An air
tight storm damper is part of the
equipment.
These ventilators. by filtering the
air, reduce the amount OF cleaning
that is needed IN the room. The air
drawn in through these units con-
stantly cirCulateS and keeps the
room in a livable condition. They
can even be used in Photographic
dsrkrooms.
New Type Insecticide.
Another summer trouble is the
moth problem. Here is a moth-kill-
ing device that is rather elaborate
but very effective. 1t is applied by
means of a sprayer that is remark
ably inexpensive.
The inSecticide used is harmless
to food, odorless, tasteless and
stainless 1t also is on-injuriouS to
human beings and the family dog
or cat.
Its effect is lasting but not per-
manent. Nevertheless, it requires
fewer applications during the sea-
son than most other preparations
and it is not necessary to seal up the
room when the application is made.
The theory of the killing is in
teresting. if slightly blood thirsty.
Insects do not breathe through
lungs but absorb the air through
the body, principally in the regions
around the legs and wings The
vapor from the insecticide enters
these breathing areas and the in
sect is forced into the open where
he dies of convulsions. The victims
will include mosquitoes, reaches,
carpet beetles, moths and num-
Der of other undesirable members
of the insect family.
Washable Shades.
Window shades are another neces-
sity of summer months. BY properly
shading and closing the windows
the temperature within doors can
be considerably reduced. A good
shade cloth is necessity, and one
that can be cleaned without too
much trouble is a blessing. These
particular shades are made by one
of the best known manufacturers in
the country and they can be re-
neWed by washing with ordinary
soap and water.
To clean the shade is unlocked
from the brackets and spread on a
fat surface. Hot water is applied
and then soap. This is scrubbed
in on both sides and then the shade
is rinsed off in clean water. When
this is finished the shade is re-
placed on the brackets. pulled out
to its fullest extent and allowed to
dry.
