I suppose one dare not write on Limehouse without mentioning opium-rooms. Well, if one must, one must, though I have nothing of the expected to tell you. I have known Limehouse for many years, and have smiled many times at the articles that appear perennially on the wickedness of the place. Its name evokes evil tradition in the public mind. There are ingenuous people who regard it as dangerous. I have already mentioned its sinister atmosphere; but there is an end of it. There is nothing substantial. These are the people who will tell you of the lurking perils of certain quarters of London--how that there are streets down which, even in broad daylight, the very police do not venture unaccompanied. You may believe that, if you choose; it is simply a tale for the soft-minded with a turn for the melodramatic. There is no such thing as a dangerous street in London. I have loafed and wandered in every part of London, slums, foreign quarters, underground, and docksides, and if you must have adventure in London, then you will have to make your own. The two fiercest streets of the metropolis--Dorset Street and Hoxton Street--are as safe for the wayfarer as Oxford Street; for women, safer. And the manners of Limehouse are certainly a lesson to Streatham Hill. But we are talking of opium. We left Mr. Tai Ling on the steps of the Asiatics' Home, and from there we wandered to High Street, Poplar, to the house of a gracious gentleman from Pi-chi-li, not for opium but for a chat with him. For my companions had not smoked before, and I did not want two helpless invalids on my hands at midnight. Those amazingly thrilling and amazingly ludicrous stories of East End opium-rooms are mainly, I may say, the work of journalistic specials. A journalistic special is a man who writes thrillingly on old-fashioned topics on which he is ill-informed. The moment he knows something about his subject he is not allowed to write; he ceases to be a special. Also, of course, if a man, on sociological investigation, puts an initial pipe of opium on top of a brandy or so--well, one can understand that even the interior of the Bayswater omnibus may be a haunt of terror and wonder. Taking a jolt of "chandu" in a Limehouse room is about as exciting as taking a mixed vermuth at the Leicester Lounge.
