Another pleasure I had which, as it could be had only on a Saturday night, occasionally struggled with my love of the opera.  The pains of poverty I had lately seen too much of; but the pleasures of the poor, their consolations of spirit, and their reposes from bodily toil, can never become oppressive to contemplate.  Now, Saturday night is the season for the chief, regular, and periodic return of rest for the poor.  For the sake, therefore, of witnessing a spectacle with which my sympathy was so entire, I used often on Saturday nights, after I had taken opium, to wander forth, without much regarding the direction or the distance, to all the markets, and other parts of London to which the poor resort of a Saturday night for laying out their wages.

Sometimes in my attempts to steer homewards by fixing my eye on the Pole star, and seeking ambitiously for a north-west passage, instead of circumnavigating all the capes and headlands I had doubled in my outward voyage, I came suddenly upon such knotty problems of alleys, such enigmatical entries, and such sphinx’s riddles of streets without thoroughfares, as must, I conceive, baffle the audacity of porters, and confound the intellects of hackney coachmen.  For all this I paid a heavy price in distant years, when the human face tyrannised over my dreams, and the perplexities of my steps in London came back and haunted my sleep with the feeling of perplexities, moral and intellectual, that brought confusion to the reason, or anguish and remorse to the conscience.

III.—­A Fearful Nemesis

Courteous reader, let me request you to move onwards for about eight years, to 1812.  The years of academic life are now over and gone—­almost forgotten.  Am I married?  Not yet.  And I still take opium?  On Saturday nights.  And how do I find my health after all this opium-eating?  In short, how do I do?  Why, pretty well, I thank you, reader.  In fact, though, to satisfy the theories of medical men, I ought to be ill, I never was better in my life than in the spring of 1812.  To moderation, and temperate use of the article I may ascribe it, I suppose, that as yet, at least, I am unsuspicious of the avenging terrors which opium has in store for those who abuse its lenity.

But now comes a different era.  In 1813 I was attacked by a most appalling irritation of the stomach, and I could resist no longer.  Let me repeat, that at the time I began to take opium daily, I could not have done otherwise.  Still, I confess it as a besetting infirmity of mine that I hanker too much after a state of happiness, both for myself and others.  From 1813, the reader is to consider me as a regular and confirmed opium-eater.  Now, reader, from 1813 please walk forward about three years more, and you shall see me in a new character.

Now, farewell—­a long farewell—­to happiness, winter or summer!  Farewell to smiles and laughter!  Farewell to peace of mind!  Farewell to hope and to tranquil dreams, and to the blessed consolations of sleep.  For more than three years and a half I am summoned away from these.  I am now arrived at an Iliad of woes.
