Phase 1

Of the Publishers and Authors of Street-Literature. (Volume 1): "The present street literature printers and publishers are, Mrs. Ryle (Catnach’s niece and successor), Mr. Birt, and Mr. Paul (formerly with Catnach), all of the Seven Dials; Mr. Powell (formerly of Lloyd’s), Brick-lane, Whitechapel; and Mr. Good, Aylesbury-street, Clerkenwell. Mr. Phairs, of Westminster; Mr. Taylor, of the Waterloo-road; and Mr. Sharp, of Kent-street, Borough, have discontinued street printing. One man greatly regretted Mr. Taylor’s discontinuing the business; 'he was so handy for the New-cut, when it was the New-cut.'"

Boy Crossing-Sweepers and Tumblers. (Volume 2): "We came up to London, and mother took two rooms in Westminster, and I and sister lived along with her. She used to make hair-nets, and sister helped her, and used to take ’em to the hair-dressers to sell. She made these nets for two or three years, though she was suffering with a bad breast;—she died of that—poor thing!—for she had what doctors calls cancer—perhaps you’ve heard of ’em, sir,—and they had to cut all round here (making motions with his hands from the shoulder to the bosom). Sister saw it, though I didn’t."
