“Having lived near a month in this manner, like a sword with ten thousand edges, to which they have been compared, upon the ruin and destruction of every vegetable substance that came in their way, they arrived at their full growth, and threw off their nympha state by casting their outward skin. To prepare themselves for this change, they clung by their hinder feet to some bush, twig, or corner of a stone; and immediately, by using an undulating motion, their heads would first break out, and then the rest of their bodies. The whole transformation was performed in seven or eight minutes; after which they lay for some time in a torpid and seemingly in a languishing condition; but as soon as the sun and the air had hardened their wings, by drying up the moisture that remained upon them after casting their sloughs, they reassumed their former voracity, with an addition both of strength and agility. Yet they continued not long in this state before they were entirely dispersed, as their parents were before, after they had laid their eggs; and as the direction of the marches and flights of them both was always to the northward, and not having strength, as they sometimes had, to reach the opposite shores of Italy, France, or Spain, it is probable they perished in the sea: a grave which, according to these people, they have in common with other winged creatures. The locust, I conjecture, was the noisome beast, or the pernicious destructive animal, as the original words may be interpreted, which, with the sword, the famine, and the pestilence, made the four sore judgments that were threatened against Jerusalem. The Jews were allowed to eat them; and, indeed, when sprinkled with salt and dried, they are not unlike in taste to our fresh-water crayfish.” Among the fish on the coast of Barbary the most curious is the penna marina, or sea-feather, which the fishermen sometimes find entangled in the meshes of their nets; and which, during the night, is so remarkably glowing and luminous as to enable the fishermen to discover by their light the size and quantity of the other fish which may happen to be enclosed within the same net.
