The pioneers 'of this country had
many hardships to overcome, but al-
so many blessings. One of these was
the availability of plenty et timber..
Most first generatioe farm buildings
were, therefore, log buildings. The
walls were thick, since there was no
need to save. material, and since wood
is a fair insulating material, the
buildings were warm. Soon we de-
stroyed most of our free timber, and
with the coming of the ,sawmill, we
cut the logs into planks and boards
so that a tree -was made to cover a
large area. Very soon there develop-
ed the idea, probably encouraged` by
early the,
dealers. that air spaces
between layers of lumber were as
Good buildings whether they be for
humans or for live stock must hate

to resist racking by wind and to ear-

strong enough to carry the likely
snow load and they must be waren
enough to ensure the necessary com-
fort required for their purpose.
In most regards our farm buildings
are satisfactory but many of them are
not so warm as they might be, they
lack proper insulation.

good insulating material as the solid
timber, and this fallacy Is still prev-
alent, not only among laymen but
among carpenters and other mem-
bers of the building trades:
I.t is true that "dead" air, or air
at rest, as is the case when it is
trapped in small oells where it can..
not circulate, is a very fair insula-
tor. However, air as it is found in
the 4 inch air space of the wall of •a
frame house it is not quiet or "dead."
In winter this air in contact with the
outside boarding of the wall is al-
ways being ,cooled by, contact with
this cold surface, while the air in
contact with the boarding or plaster
on the inside surface of the studding
albsorbs the bleat conducted through
this covering. Now, air rises when
warmed, and falls on cooling, there-
fore the air in the wall of a frame
house is ,practically never quiet so
long as the •coverings, on the two sides
of the airspace are at different tem-
peratures. Indeed, the fact that the
air ie in motion in these spaces, as-
sists in the transfer of -heat through
these walls since it acts as a vehicle
for``moving the heat frothe'oele side of
the space to the other. The action of
loose„ filler type 'insulators as rock
wool,. ground cork, glass wool, Palco
Wool, Insulex and :planer shavingsis
largely one of breaking these large
air spaces into millions of small cells,,
thus effectively preventing this air
movement..
_ Thin Air Space is Best
Tests have shown that thin air
spaces are more effective insulation
than are the four inch Spaces be-
tween- the studs of the ordinary frame
Wall. Three-quarters of an inch air
space has been found best for this
thickness. It is 'sufficient• for insula-
tion• but so thin that friction within
thenarrow space in which it is con-
fined prevents, movement. Vertical
air spaces in walls mustbe broken
into columns not much, over two feet,
high so as to prevent movement.
Because of new developments in
insulating materials• it is wise to spend
a little time looking into the basic
forces. responsible for the loss of heat
through the various materials used in
buildings, which are artificially heat-
ed. Heat passes through' practically
all kinds of materials used in build-
ings, but some allow it to pass, more
readily than others, such as stone,
concrete. steel and brick. This qual-
ity in them is not desirable for build-
ings which are meant to keep us
warm, but they have so many other
good structural qualities that they
are very valuable in spite of this de-
fect. When these •materials, are used
insulation must be added in the forme
of layers of materials which are poor
conductors of heat. The more ',near-
ly the temperature of the surface of
the wall of a house is 'to the temper-
ature of the air in the. house the bet-
ter the insulating qualifies Of that
wall. Some walls feel cold to the
touch indicating that the sheat is be-
ing very rapidly extracted from the
air in contact with that surface and
conducted through the wall.
Heat, is also transferred from one
material to another by, radiation.
Thus a person sitting some distance
from a stove will fesel the warmth
though the air around him is con-
siderably cooler. The heat df the
sun, foe example, is brought -to .the
earth by radiation. The atmosphere
is a poor absorber of radiant heat
except when it contains moisture.
Thus clouds located between us and
the sun will intercept the heat rays
from: the sun explaining the fact that,
on a cool sunny day, we immediate=
ly feel cooler when an occasional
cloud obscures the sue.
Practically all stoves and fur-
nace§ used for heating of buildings
transfer the heat • from the fuel to
the air in the building by ineans of
'radiation. Dry air, however, Is a poor
absorber of heat; it is the moisture
in it which has they ability to absorb
heat, this being one very good reason
not to let the air in our dwellings
get too dry.
Insulate Fen Warmth
-Some surfaces are much better rad-
iators of heat than others and a sur-
face which radiates .heat readily also
absorbs it readily. Dark, rouge 'sur-
faces are best for radiating heat. A
bright, 'polished .surface is a poor rad-
iator also a poor •absorber of radiant
heat. That is why tea kettles and
sotip tureens with brightly nickelled
surfaces hold tho contents hot much
longer than do drill colored vessels.
It is an interesting fact also, that in
the thermos ;bottle with which all of
us are now faniilfer, we have a vessel
made ()fee combination of poor cora`
ducting ands• poor radiating niateria;l.

Readers of Saturday Nieght will
probably have noticed 'in' recent
sues .of this and of- many other, 'per-
iodicals an increasing auloat of a
type of advertising which ds cormm,on-
ly known in the procession as "instl-
tutional," and wh%h aiuos_lsass at ef-
illtilletteingeopine
ion. There are very good reasons at
the moment why this type of adver_
Using should increase, and very good
reasons also, we think, why its in-
crease should on the whole 'be bene-
ficial to the community.
We are entering a period during
which, on aioount of the increased
impait of taxation and government
regulation upon every species of ac-
tivity, it will be nee'essaayj to make
many important changes, in our econ-
omic and social system.,Whether
these changes are to to be made in-
telligently and with moderation, or
recklessly and without consideration
for their ulthnate effect upoi effici-
ency of production and justice of dis-
tribution, will depend largely on the
amount of infermkation available to
the thoughtful citizen concerning the
'business enterprises of his country
and the way in which they are con-
ducted. '
No intelligent executive of the
present day dreams of adapting the
slogan "My business is none 'of your
business" which used to be the very
password of the _:clan. Those days are
gone, and business men are aware of
it, and aware also that the 'most mag-
nificent list of assets in the way of
plant and stare and organization and
trade connections may be valueless
if the one asset of public good will
is lacking. - And what. is true of the
individual 'business is .true of baYsi_
nesss .enterprise regarded as a whole.
If it is to come through the testing
times that are abead of us with un-
neither absorb or radiate the beat
waves. This"explains the extreme ef-
fectiveness of the thermos bottle in
keeping its contents either warmer or
colder than that of the surrounding
atmosphere for long periods of time.
This ability of bright surfaces to
turn •back waves of radiated heat has
been turned to good use by putting
very thin sheets of aluminum in rail-
road coaches, trucks, steamships and
even on some types of plaster board.
Various materials have been tested

Pine lumber, far, example, has
nearly threetimes as high •a K fac-
tor as, have, commercial insulating
boards: Or, stated in another way.„
it would take nearly three. inches. of
solid lumber to equal the insulating
value of one inch of the commercial
insulating beards cited. Also, an inch
of dry planer shavings, fairly well
packed is as .effeticve as a wo inch
packed is as effective as a two tinclu
layer' of solid lumber. It-eshould 'al-
ways be remembered, however, tlla.t
all ,loose .,filler insulators have no
structural value, having to be held in
placeby sheets of other materials,
whieh give the building rigidity and
strength. „ ,
Another important observation from
this table •is; the high heat loss fac-
tors of almost any type of masonry
and concrete. Yet, because of their.
permanence in contact with the earth
and (because of their high compres-
sive strength -these materials are
needed regularly for foundations of
buildings. •

of the credit structure, without which

either credit or industry are already
demanding a chance to tinker with
their delicate machinery. Much wilt
