Parmentier
planted 100 acres of potatoes outside Paris and kept the
crop under heavy guard, a strategy that convinced nearby
villagers (and ultimately the entire country) that the starchy, misshapen lumps were desirable.
If the stars are faint and become visible a day or two later than normal, the
villagers believe a drought must be coming, and they postpone
planting the potato
crop by 4 to 6 weeks.
