"Not exactly; but a decent local builder was rather taken with it when I showed it to him, and he’s giving it a trial at the new Literary Institute he’s putting up.  The building was stopped by the war, but he has already started work again, and he’s willing to test the idea before the plasterers finish. He has rigged up a sort of tray on the laths in the roof of the big room, and one of these days is going to put a brazier underneath. You see, if the stuff melts too easily, it will only mean a slop on the floor, and won’t do any damage."
