"Digging for potatoes" from the London Illustrated News, 1849:
"'Searching for Potatoes' is one of the those occupations of those who cannot obtain outdoor relief. It is gleaning in a potato field, and how few are left after the potatoes are dug, must be known to everyone whohas ever seen the field cleared. What the people were digging and hunting for, like dogs after truffles, I could not imagine, till I went into the field, and then I found them patiently turning over the whole ground, in the hopes of finding the few potatoes the owner might not have overlooked. Gleaning ina potato field seems something like shearing hogs, but it is theonly means by which the gleaners could hope to geta meal."
