I —. — '■ TO THE EDITOR. Sir,— My attention having been called to a letter signed " Damper," published in your issue ef the 10th inst., and also to the leader in your issue of the next day, highly commending "Damper's" idea, I beg re spectfully to inform " Damper" that he is just a little behindhand with iiis " notion," as I have carried the idea into effect some weeks ago in a house I have built in Ettrick street. Strange to say, your corre spondent "Damper," in describing what he is pleased to call Ms " notion," repeals, almost word for word, the language l" ha /o from time to time used when explaining t se idea to friends and others who I thoug ;t might feel interested. I should be sorry to accuse " Damper" of pirating tao notion; still, I must confess, it looks very much like it. I think, Sir, under the circumstances I may be excused for sus pecting the writer to be one of those who have seen the notion carrier! into effect in my house, or heard my description of it. It" he is riot the psraon I suspect him to be, and will give hi 3 name, I should of course willingly apologise. As he appears to regret not having a house to try the notion ou, 1 may state that I shall bo happy to show him or you, Mi- Editor, the idea in proper working order any time he may think fit to honor me with a call. In the ineaotims I may state that the idea is well worth the consideration o£ parties about to build. If adopted when the house is being built the cost would be about 25s for each fireplace, but the cost would, o£ course, be governed fay the weight of iron used. I used 16 gauge, but sheuld have used heavier had it been obtainable at the time, as light iron would have a tendency to buckle if drawn down before a large lire. If adopted in houses already built, the cost would be greater. The best time to do it would be when rooms are about to be repapered,. The chimney breastwork could then ba easily removed and the dampsr, fixed in position.
