The others sat by the window, and the old man and Felix, finding in each other much that was congenial, talked unreservedly of many matters. It seemed to be tacitly understood that the painful incidents which had occurred on the day of the funeral should not be spoken of, and no reference was therefore made to them. Lily took but little part in the conversation; she sat and listened with a soul in harmony with everything about her. It was very seldom that her grandfather had the opportunity of enjoying a quiet hour with a nature which so nearly resembled his own. Both he and Felix evidently loved to look at common things from almost an ideal point of view, and the most ordinary matters, as they conversed upon them, were occasionally invested with bright bits of colour which matter-of-fact and prosaic minds would have utterly failed to see. Only once was Lily's mother referred to; the reference arose from a remark made by Felix concerning the singular peculiarity in the room that nearly everything was on castors. The old man explained that it originated from his daughter's sickness. "Every little noise fretted her," he said, "and as I had learnt turning in my young days, I amused myself by making small wheels to whatever I laid hands on, so that it could be moved about without noise. It was not quite an idle whim, therefore; it has occupied my time, which otherwise would have hung heavily, and I have really grown to believe that it could be made to serve many useful purposes. The man who first conceived the idea of a wheel was a great benefactor. Civilization," he added, with a pleasant laugh, "would be at a standstill without its wheel." One thing leading to another, in the course of conversation they found themselves conversing upon deeper than mundane matters. They had been talking of the comparative value of creeds, and the old man said, "Faith is everything. So long as a man believes--if his belief be associated with anything that is pure and good in itself--it matters little what it is. To me it is the worst kind of arrogance, the worst kind of intolerance, for a man to say, 'Believe as I believe, or you are lost.'" "And those who don't believe?" suggested Felix.
