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 the sante fundamentals if they are ' to be satisfactory. In other words they roust have good foundations placed below frost level so that they will not heave; they must be strong enough to resist racking by wind and to ear- --17.-internal loads; -thief lie 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. Insulation is the method whereby we present heat -''transfer, because, •) while we want tb prevent heat loss through the walls and the roofs in winter, in summer we are anxious to prevent the heat of the summer sun from coming in. We should remem- ber. therefore; that the subject of ins sulation in buildings' always deals with the transfer of heat through the walls, roofs and floors of our build- ings rather than with the keeping out Buy FOR VICTO Your Dollars__ Will Come Marching Home Your pennies, your quarters, your dollars are need- ed in this war as much as the men at the front.

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.

Sandwell In Saturday Melt) 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 and the' rapidity withwhich they al- low heat to pass through :calculated. (Engineers call this, the K factor). In this table the greater the heat loss the higher the figures shown.

Fortunately for business, it has never had a more dramatic., more in- teresting or more favor -winning story to tell the publicthan it bas in Can- ada today. But for the !highly effici- ent and well' integrated structure of Canadian industry and transportation and in that structure we include the skilled labor without which all else would be worthless^—it is highly pos- sible that Herr Hitler would today be dictating to the world from Bucking- ham Palace. We live in a world which industrial capacity is as 4� portant as fighting wan -power in de- termining the issues of war, and if Great°Bri•tain'could not rely on the , industrial capacity of the Empire as well as a great part of that of the United States, she 'would have been defeated long ago. The same is true. of the credit structure, without which the industrial machine could not func- tion. In the name of reform, politi- cians unskilled in the management of either credit or industry are already demanding a chance to tinker with their delicate machinery.
