He divided the contents of the bottle (not quite fairly) between the two cups. He gave himself the advantage of the choice and finished his drink at a draught. I followed his example and found that I was drinking distilled water. At this I was somewhat disappointed, but the more disposed to forgive him for the injustice of the division. "And now, my friend," he said, "we can talk." "Then," I replied, "you will perhaps tell me what is the reason for the custom which prevents you from taking your drink in a sociable manner. In the country from which I come we like to sit and chat over our glass." "So it was here also in the dark ages," said my host. "At that time our drink was for the most part of an alcoholic character, and it was found that the more one talked, the more one drank; and the more one drank, the more one talked. It was a vicious circle of foolishness and ill-health, and the practice was made illegal. Alcoholic drink is quite unknown now among the first-class beings of Thule. But the custom of not speaking when one drinks, although we now only drink water, still remains. It is one of the many instances in which the ritual has survived the religion." I pointed now to the grating in the floor. "A ventilator, I suppose." "Exactly. It is actuated once every hour for two minutes. It draws out carbon dioxide, which being heavier than air is in the lower part of the room, and at the same time draws in fresh air through the corresponding grating in the ceiling, which communicates with a shaft to the open. The great point about it is that it is absolutely noiseless. Our study of longevity has shown us that irritation is one of its deadliest enemies. The noise of an electric fan is irritating, especially in a bedroom. I dare say the crude appliances you have in the old world still whir or clatter." "I notice that all your electric lights are fixed in the ceiling itself. Is there any reason for this?" "Naturally. Anything which hangs may subsequently fall. We do not court dangers. It is curious that you should mention it, because I was speaking of this point only last week to my friend, the Professor. He showed me a picture of an old-world chandelier. He also told me it was the custom in England and other uncivilised parts of the world to daub oil-paints on a piece of canvas. This was surrounded by a heavy frame and was suspended on walls. It was called a framed picture. You will find nothing so reckless here. By the way, I have found out about England. I cross-spoke to the Outer Office, and they told me it was a piece of land at the back of Scotland." I found later that "to cross-speak" meant in Thule to send a wireless message. "The mention of the Professor," my host continued, "reminds me that to-day is his birthday and mine. On this day I generally make him a ceremonial visit, and I shall be pleased to take you with me. As a specimen you will interest him." "Might I ask what you mean by the Outer Office?"
