Widgeon Duck, 1790
Way to intoxicate Water-Fowl. First clean, and then steep in clear Water, for full 4 hours, the Roots, Leaves, and Seeds of the herb Bellenge; then boil them in the same Water, till it is almost all evaporated; and after it is cold, throw it in the places where the Fowls frequent, who, eating eagerly of it, will be made so drunk as to be readily taken; but no time must be lost in catching them, for they will soon recover.
