After a few days he called, in person, at each house and shop to see who would subscribe sixpence a month. It was a great success. The cleanliness of the pavement in the important streets surrounding the market, greatly delighted the people, and prepared the way for carrying a bill which Franklin presented to the Assembly for paving and lighting all the important streets of the city. A gentleman, by the name of John Clifton, had placed a lamp before his door. This suggested the idea. Lamps were sent for from London. Globes were furnished. They were expensive. The smoke circulated in the globe and obstructed the light. They had to be wiped clean each day. An accidental stroke demolished the whole globe. Franklin suggested four flat panes. One might be broken, and easily replaced. Crevices were left below to admit a current of air, and a funnel to draw off the smoke. Thus for a long time the glass remained undimmed. Wherever Franklin went, he carried with him this spirit of improvement. When in London, he found the streets wretchedly dirty. One morning he found a poor woman at his door in Craven street, sweeping the sidewalk with a wretched broom. Her pallid and exhausted appearance touched the sympathies of Franklin. He asked who employed her. She replied: "Nobody. I am poor and in distress. I sweeps before gentlefolks's doors, and hopes they will give me something." Franklin immediately engaged her to sweep the whole street. It was nine o'clock in the morning. She was so languid and debilitated that he thought it would take her nearly all day. But in three hours she came for her shilling. Franklin thought she could not have done her work faithfully. He sent his servant to examine. He reported that the work was thoroughly done. A new problem rose before Franklin: If this feeble woman could in so short a time sweep such a street, a strong man, with a suitable broom, could certainly do it in half of the time. He therefore drew up a plan for cleaning the streets of London and Westminster, which was placed in the hands of one of the most influential of the public-spirited men of London. Franklin apologizes for speaking in his autobiography of such trifles. Very truly, he says, "Human felicity is produced not so much by great pieces of good fortune that seldom happen, as by little advantages that occur every day. Thus if you teach a poor young man to shave himself and keep his razor in order, you may contribute more to the happiness of his life than in giving him a thousand guineas. This sum may be soon spent, the regret only remaining of having foolishly consumed it. But in the other case, he escapes the frequent vexation of waiting for barbers, and of their sometimes dirty fingers, offensive breath, and dull razors. He shaves when most convenient to him, and enjoys daily the pleasure of its being done with a good instrument."
