The Illustrated annual register of rural affairs and cultivator almanac for the year .. . warm tlie whole house ; for asit now is, the stove is only large enough to drive all the cold back intothe remote parts of the house, where myself and others sit, and we arenow colder than before. This remark was considered by some as espe-cially absurd; but after all, he was right, although the rationale wasrather fallacious. One fact to illustrate our meaning. We have gone into a room in win-ter where there was no fire, and where every door and window appearedto shut so closely that not the least current could be perceived from anycrevice. A fire has then been built in the fire-place, and immediately theshrill singing of air currents entering crevices before unknown, showedthat the rapid draught up the chimney required supply from without, andthat the cold air was rapidly rushing in for this purpose. Of course,near these window currents, it must be colder than before. Precisely inthe same way, the deacon above spoken of, found that the cold currents 6 122 ILLUSTRATED ANNUAL REGISTER. from without had increased by the introduction of the stove ; the draughtof the fire requiring a constant supply of air. This fact furnishes some important suggestions on the subject of venti-lation. There is no question that the air in many of our rooms in winter,becomes close, and unwholesome to breathe ; but where there is a strongdraught, either up the throat of a fire-place or through the pipe of a,stove, the circulation is quite sufficient to maintain good fresh air for all the ordinary purposes of breathing, providedI the circidaiion is in the right direction. Theair rushes in through window crevices, andpasses directly towards the fire. These enteringcurrents immediately descend, because, first,they are much heavier than the air of the experiments of Gay Lussac proved that aira few degrees below freezing, (about 24* Eah.,)is about one-tenth heavier than air in a room at68*.
