The gracious gentleman received us affably. Through a curtained recess was the small common room, where yellow and black men reclined, in a purple dusk, beaded with the lights of little lamps. The odour was sickly, the air dry. The gentleman wondered whether we would have a room. No, we wouldn't; but I bought cigarettes, and we went upstairs to the little dirty bedrooms. The bed is but a mattress with a pillow. There, if you are a dope-fiend, you may have your pipe and lamp, very cosy, and you may lock the door, and the room is yours until you have finished. One has read, in periodicals, of the well-to-do people from the western end, who hire rooms here and come down, from time to time, for an orgy. That is another story for the nursery. White people do visit the rooms, of course, but they are chiefly the white seamen of the locality; and, in case you may ever feel tempted to visit any of the establishments displaying the Sign of the Open Lamp, I may tell you that your first experiment will result in violent nausea, something akin to the effect of the cigar you smoked when you were twelve, but heightened to the _n_th power. Opium does nasty things to the yellow man; it does nastier things to the white man. Not only does it wreck the body, but it engenders and inflames those curious vices to which allusion has been made elsewhere. If you do not believe me, then you may accept the wisdom of an unknown Formosan, who, three hundred years ago, published a tract, telling of the effects of the Open Lamp on the white man. They are, in a word, parallel with the effects of whisky on the Asiatic. Listen:-- The opium is boiled in a copper pan. The pipe is in appearance like a short club. Depraved young men, without any fixed occupation, meet together by night and smoke; and it soon becomes a habit. Fruit and sweetmeats are provided for the sailors, and no charge is made for the first time, in order to tempt them. After a while they cannot stay away, and will forfeit all their property so as to buy the drug. Soon they find themselves beyond cure. If they omit smoking for a day, their faces become shrivelled, their lips stand open, and they seem ready to die. Another smoke restores vitality, but in three years they all die. So now you know. The philanthropic foreigner published his warning in 1622. In 1915 ... well, walk down Pennyfields and exercise your nose, and calculate how much opium is being smoked in London to-day.
