RIIS, JACOB A. : When nothing seems to help, I think of a stone-cutter hammering away at his rock perhaps a hundred times without as much as a crack showing in it. Yet at the hundred and first blow it would split in two, and I know it was not that blow that did it, but all that had gone before together. (Jacob A. Riis, Danish-American social reformer, journalist, and social documentary photographer, 1849-1914)
