Drowsily they whirred all through this sunny day, making the passenger more sleepy and more hot as he passed the humming walls of the mills. Sun-blinds, and sprinklings of water, a little cooled the main streets and the shops; but the mills, and the courts and alleys, baked at a fierce heat. Down upon the river that was black and thick with dye, some Coketown boys who were at large⁠—a rare sight there⁠—rowed a crazy boat, which made a spumous track upon the water as it jogged along, while every dip of an oar stirred up vile smells. But the sun itself, however beneficent, generally, was less kind to Coketown than hard frost, and rarely looked intently into any of its closer regions without engendering more death than life. So does the eye of Heaven itself become an evil eye, when incapable or sordid hands are interposed between it and the things it looks upon to bless.
