made in a similar manner; that is, by enclosing hard-burned glazed pipe in a thin wall of bricks.  Such chimneys will not only draw better than those made in the usual way, but there will be less danger from ‘defective flues.’  A four-inch wall of bricks between us and destruction by fire is a frail barrier, especially if the work is carelessly done or the mortar has crumbled from the joints.  To build the chimneys with double or eight-inch walls makes them very large, more expensive, and still not as good as when they contain the smooth round flues.  To leave an air-chamber beside or between them for ventilating (Fig. 2), is better than to open directly into the smoke-flue, because it will not impair the draught for the fire, and there will be no danger of a sooty odor in the room when the circulation happens to be downward, as it will be occasionally.  The outside chimney, if there is one, should have an extra air-chamber between the very outer wall and the back of the fireplace to save heat (Fig. 3), a precaution that removes to a great extent the common objection to such chimneys.  Whatever else you do, let these ’windpipes of good hospitalitie’ have all the room they need.  I shall not willingly carry them off by any devious way to be hidden in an obscure corner or dark closet, nor yet to give them a more respectable and well-balanced position on the roof.  Like the wild forest trees they shall grow straight up toward heaven from the spot where they are first planted.  If we happen to want a window where the chimney stands in an outer wall we will make one between the flues, as one might build a hut in the huge branches of a mighty oak.  It isn’t the best place for the window or the hut, but circumstances may justify it; as, for instance, when we must have the outlook in a certain direction, but cannot spare the wall-space for a window beside the chimney.  The jambs beside a window so situated will be very wide, and you may, if you please, extend the view of the landscape indefinitely by setting two mirrors vis-a-vis in the opening at either side.  This will also send the sunshine into the room after the sun has passed by the other windows on the same side of the house.  It is rather a pretty fancy, too, when the outside view does not require a clear window, to set a picture in colored glass above the mantel, and the same thins:  may be arranged in the sideboard, if it happens to stand against the outer wall.  These are fancies, however, which lose their beauty and fitness unless they seem to have been spontaneously produced.  There should be no apparent striving for effect.”

“I like the idea of setting mirrors in the deep window-jambs, whether they are in the chimney or out of it,” said Jill.  “If I was obliged to live in a room where the sun never shone of its own accord, I would set a trap for it baited with large mirrors fixed on some sort of a windlass in a way to send the sunshine straight into my windows.”
