The obscure streets of life do not offer the conveniences of the central thorough fares: no electric light, no gas, not even a kerosene lamp-bracket. There are no pave ments: the traveller has to fumble his way in the dark. If he needs a light, he must wait for a thunderbolt, or else, primitive-wise, knock a spark out of a stone. In a glimpse will appear unfamiliar outlines; and then, what he has taken in he must try to remember, no matter whether the impression was right or false. For he will not easily get another light, except he run his head'against a wall, and see sparks that way. What can a wretched pedestrian gather under such circumstances? How can we expect a clear account from him whose curiosity (let us suppose his curi osity so strong) led him to grope his way among the outskirts of life? Why should we try to compare his records with those of the travellers through brilliant streets?
