There are other difficulties connected with furnaces which should be considered. It is necessary to perfect health that an equal circulation of the blood be preserved. The greatest impediment to this is keeping the head warmer than the feet. This is especially to be avoided in a nation where the brain is by constant activity drawing the blood from the extremities. And nowhere is this more important than in schools, churches, colleges, lecture and recitation-rooms, where the brain is called into active exercise. And yet, furnace-heated rooms always keep the feet in the coldest air, on cool floors, while the head is in the warmest air.
Another difficulty is the fact that all bodies tend to radiate their heat to each other, till an equal temperature exists. Thus, the human body is constantly radiating its heat to the walls, floors, and cooler bodies around. At the same time, a thermometer is affected in the same way, radiating its heat to cooler bodies around, so that it always marks a lower degree of heat than actually exists in the warm air around it. Owing to these facts, the injected air of a furnace is always warmer than is good for the lungs, and much warmer than is ever needed in rooms warmed by radiation from fires or heated surfaces. The cooler the air we inspire, the more oxygen is received, the faster the blood circulates, and the greater is the vigor imparted to brain, nerves, and muscles.
Scientific men have been contriving various modes of meeting these difficulties, and at the close of this volume some results will be given to aid a woman in selecting and managing the most healthful and economical furnace, or in providing some better method of warming a house. Some account will also be given of the danger involved in gas-stoves, and some other recent inventions for cooking and heating.
VI.
HOME DECORATION.
Having duly arranged for the physical necessities of a healthful and comfortable home, we next approach the important subject of beauty in reference to the decoration of houses. For while the aesthetic element must be subordinate to the requirements of physical existence, and, as a matter of expense, should be held of inferior consequence to means of higher moral growth; it yet holds a place of great significance among the influences which make home happy and attractive, which give it a constant and wholesome power over the young, and contributes much to the education of the entire household in refinement, intellectual development, and moral sensibility.
Here we are met by those who tell us that of course they want their houses handsome, and that, when they get money enough, they intend to have them so, but at present they are too poor, and because they are poor they dismiss the subject altogether, and live without any regard to it.
We have often seen people who said that they could not afford to make their houses beautiful, who had spent upon them, outside or in, an amount of money which did not produce either beauty or comfort, and which, if judiciously applied, might have made the house quite charming.
For example, a man, in building his house, takes a plan of an architect. This plan includes, on the outside, a number of what Andrew Fairservice called "curlywurlies" and "whigmaliries," which make the house neither prettier nor more comfortable, and which take up a good deal of money. We would venture to say that we could buy the chromo of Bierstadt's "Sunset in the Yosemite Valley," and four others like it, for half the sum that we have sometimes seen laid out on a very ugly, narrow, awkward porch on the outside of a house. The only use of this porch was to cost money, and to cause every body who looked at it to exclaim as they went by, "What ever induced that man to put a thing like that on the outside of his house?"
Then, again, in the inside of houses, we have seen a dwelling looking very bald and bare, when a sufficient sum of money had been expended on one article to have made the whole very pretty: and it has come about in this way.
