There should be a triple water supply in the House Comfortable; ewers always filled from the soft-water pump. Every well and tank should be tested ere we take up residence. Pure water, and plenty of it, is essential to the health (and therefore comfort) of every household. It should be perfectly clear and bright, and free from taste or smell. Yet impurity may lurk even in the most sparkling water. Therefore science must decide as to its desirability. If only iron or lime water is procurable, jars of lump ammonia, or a bottle of cloudy liquid ammonia, a bag of oatmeal or a bundle of bran should lie on every washstand. The hot-water boiler not only supplies unlimited baths, but may be devised to heat the house. In every Canadian home a stove in the cellar warms the rooms above by means of drums and fans. We might do much the same in England with our hot-water pipes. These should certainly run through the linen-press and clothes cupboards, and terminate in bathroom spirals. On these, towels and rough sheets could be dried and aired. A face cloth always warm is one of the luxuries in our House Comfortable. After sanitation, ventilation takes its place in the home. How to secure a constant supply of fresh air is a question which demands most serious consideration. In ages past, houses were unintentionally ventilated by the ill-fitting doors and window-frames, wide chimneys, and open fire-places. But in our modern buildings comfort is secured by almost air-tight doors and windows. Ventilators at the top of such are delightful and necessary for real comfort, or a Queen Anne casement may have a swing in its upper frame. It is not always easy, however, to secure exemption from draught in our modern mansions. When the brick-and-mortar fiend has placed door, window, and fireplace exactly opposite each other, screens must be judiciously used. A brass rod from which hangs a curtain, screwed into the door jamb and suspended by a tiny chain from the ceiling, is a good thing, or an ordinary _portière_ may be allowed. The former plan, however, enables us to keep the door open without feeling a wind. Padded stair-carpets secure noiseless ascent in the House Comfortable. Cork mats by the big bath are welcome to bare feet. Many cupboards are a necessity. A place for everything and everything in its place is one of the initial rules for everyone's comfort. It is also Divine law. Hanging presses, medicine cupboards, butler's pantry, housemaid's closets, keep dresses from dust, poisons from the unwary, silver and glass intact, and brushes unworn. The House Comfortable must not be over-servanted. Neither must it be undermanned. Of the two evils, the latter is preferable, as the mistress herself then looks after the minutiæ of her house. With all deference to Matthew Prior, comfort does not flow on a line with ignorance. It requires a cultivated intelligence to provide such in our homes.
