Early risers strolling along the Thames would see the toshers wading through the muck of low tide, dressed almost comically in flowing velveteen coats, their oversized pockets filled with stray bits of copper recovered from the water's edge. The toshers walked with a lantern strapped to their chest to help them see in the predawn gloom, and carried an eight-foot-long pole that they used to test the ground in front of them, and to pull themselves out when they stumbled into a quagmire. The pole and the eerie glow of the lantern through the robes gave them the look of ragged wizards, scouring the foul river's edge for magic coins.
