At that time the houses on Wapping Wall were not encumbered with dust-bins, since the river was found a more convenient receptacle for rubbish. Slops were flung out of a back window, and kitchen refuse went the same way, or was taken to the river stairs and turned out, either into the water or on the foreshore, as the tide might chance. Mrs. Grimes carried about with her in her dustings and sweepings an old coal-scuttle, which held hearth-bushes, shovels, ashes, cinders, potato-peelings, and the like; and at the end of her work, when the brushes and shovels had been put away, she carried the coal-scuttle, sometimes to the nearest window, but more often to the river stairs, and flung what remained into the Thames. Just as Mr. Cripps was at his busiest and politest, Mrs. Grimes appeared with the old coal-scuttle, piled uncommonly high with ashes and dust and half-burned pipe-lights. She set it down by the door, gave my grandfather his keys, and turned to prepare the table. Instantly Mr. Cripps, watchful in service, pounced on the scuttle. "I'll pitch this 'ere away for you, mum," he said, "while you're seein' to Cap'en Kemp's dinner"; and straightway started for the stairs. Mrs. Grimes's back was turned at the moment, and this gave Mr. Cripps the start of a yard or two; but she flung round and after him like a maniac; so that both Grandfather Nat and I stared in amazement. "Give me that scuttle!" she cried, snatching at the hinder handle. "Mind your own business, an' leave my things alone!" Mr. Cripps was amazed also, and he stuttered, "I--I--I--on'y--on'y----" "Drop it, you fool!" the woman hissed, so suddenly savage that Mr. Cripps did drop it, with a start that sent him backward against a post; and the consequence was appalling. Mr. Cripps was carrying the coal-scuttle by its top handle, and Mrs. Grimes, reaching after it, had seized that at the back; so that when Mr. Cripps let go, everything in the scuttle shot out on the paving-stones; first, of course, the ashes and the pipe-lights; then on the top of them, crowning the heap--Grandfather Nat's cash-box! I suppose my grandfather must have recovered from his astonishment first, for the next thing I remember is that he had Mrs. Grimes back in the bar-parlour, held fast by the arm, while he carried his cash-box in the disengaged hand. Mr. Cripps followed, bewildered but curious; and my grandfather, pushing his prisoner into a far corner, turned and locked the door. Mrs. Grimes, who had been crimson, was now white; but more, it seemed to me, with fury than with fear. My grandfather took the key from his watchguard and opened the box, holding it where the contents were visible to none but himself. He gave no more than a quick glance within, and re-locked it; from which I judged--and judged aright--that the pocket-book was safe.
