The choice, therefore, so far as ventilation of either house or barn goes, lies between a poorly built, loose-jointed structure without artificial ventilation and with poor economy in heat, and a well-built, air-tight structure, with ample ventilating pipes, carefully and intelligently planned and built. The first is healthy so far as pure air is concerned, but drafty and uncomfortable. The second is more expensive to build, but insures lasting health and comfort. Then the choice cannot but fall on the building which is easy to warm, healthful to live in, and readily ventilated. CHAPTER V _QUANTITY OF WATER REQUIRED FOR DOMESTIC USE_ Until the last few years it has been a sad commentary on the intelligence of the average farmer that but few attempts have been made to supply the farmhouse with running water, adequate to the needs of domestic use. The men of the farm long ago realized that carrying water for stock in pails was both laborious and time-consuming, and very few barnyards have not had running water leading into a trough to supply the needs of cattle. In many cases this supply has been extended into the barn, and in some cases into individual stalls, so that the farmer has long since eliminated the necessity of hauling water for his stock. Perhaps, because the farmer did not himself carry the water, but rather his wife, he has until recently not concerned himself with any extension of the water-supply into the house, and so long as the well in the yard did not run dry, he felt that his duty had been done. To be sure, bringing water from the well to the house in mid-winter involves much exposure and sometimes real suffering; occasionally the farmer has been moved on this account to have the well located in the woodshed or on the back stoop, avoiding the long outdoor trip, but increasing the dangers of pollution to the water. It would be interesting to make a census of the farm water-supplies in any county for the purpose of estimating the intelligence of the farm-owners, since one cannot but feel that such a primitive water-supply argues, in most cases, an undeveloped or one-sided intelligence on the part of the property owner. _Modern tendencies._
