This room is ceiled upon the inside with unmatched boards, the side walls filled with straw, about 10 inches space. In the lott straw is put in loosely, and the space between the boards caused by shrinkage is left open into the loose straw above The door into the room does not shut air tight, and therefore serves as an intake for fresh air; then very slowly passing into the straw above. In this way it would seem that a much slower circulation takes place than would if there was an opening cut directly into the loft and the circulation left free, as it would through even an ordinary out-take flue. I do not feel like speaking with much authority upon the hen business, but it is rather a lingering belief that henhouses as a rule are troubled with too much change of air rather than, a lack of it, and furthermore that the apparent need of ventilation when one goes into a house comes largely from filth, and a lack of sanitation due to droppings long preserved. 1 am not inclined to belittle the necessity of pure air, but to magnify the value of cleanliness, and so secure pure air with less frequent change. There is ground for debate whether open dead air spaces are preferable to stuffed walls. My preference is for the stuffed space, provided it is wide enough, for this reason: Each straw is hollow and cannot be abso- lutely (if dry) packed so closely to another that there will not be air between them, and hence with this means of insulation there will be pro- vided a multitude of dead-air spaces, at moderate cost, while to secure even two spaces with lumber at
