The reader who has troubled to come so far with me will not unreasonably be curious to know how opium is smoked; so, if he will accompany me farther, I will take him into a den and satisfy his curiosity. It is a Chinese den. From the street it has nothing to proclaim its character; it is like any other entrance in the street. Ah! Here comes a smoker. Observe his deathly pallor, his appearance of emaciation, his dazed expression. He must be a heavy smoker, soaked in the vice. Let us go in with him! We enter. For a moment the dimness of the room flanked on three sides with raised wooden platforms waist-high, and covered with mats, is accentuated by our sudden entrance from the sunlit street. We become aware of a peculiar odour in the atmosphere of the room, not unpleasant, but peculiar. It is like nothing that we have ever sniffed before. It is the odour of smoked opium. When our eyes, having got used to the light, or rather darkness, of the room, we look round and see on the platforms, sleeping forms sprawled round trays containing their smoking utensils. Let us examine these: First there is the pipe. It is made of a single joint of bamboo about a foot and a half long, hollow, and closed at one end, and about an inch in diameter. About a quarter of its length up from the closed end, there is an earthenware protuberance, not unlike a door-knob in appearance, firmly fixed into the stem; on its top, and in the centre, is a small orifice. This is the pipe-bowl. [Illustration: OPIUM SMOKERS’ APPLIANCES] Next we notice a lamp. This has a base of wood, and consists of a glass reservoir of oil, with a string wick leading from it through a small brass cap. Over this is a glass chimney. Then we see the wire, like an ordinary fine knitting needle; and several horn phials, each containing prepared opium.
