Phase 1

Of the Mud-Larks. (Volume 2): "At King James’ Stairs, in Wapping Wall, which is nearly a central position, from 40 to 50 mud-larks go down daily to the river; the mud-larks "using" the other stairs are not so numerous. If, therefore, we reckon the number of stairs on both sides of the river at 28, and the average number of mud-larks frequenting them at 10 each, we shall have a total of 280."
