This tree may be called the emperor’s great military magazine. In a solution of the poisonous gum which exudes from it, his arrows and offensive weapons are dipped; the procuring, therefore, of this poisonous gum, is a matter of as much attention as of difficulty. Criminals are only employed in this dreadful service. Of these, several every year are sent with a promise of pardon and reward if they procure it. Hooded in leather cases, with glass eyelet-holes, and secured as much as possible from the foul effluvia of the air they are to breathe, they undertake this melancholy journey, travelling always with the wind. About one in ten escapes, and brings away a little box of this direful commodity! Every one skilled in natural history knows, that the mimosæ, or sensitive plants, close their leaves, and bend their joints, on the least touch. This is truly astonishing: but hitherto no end or design of nature has appeared from these motions; they soon recover themselves, and the leaves are expanded as before. Dionæ Muscipula, or Venus’s Fly Trap, is a newly discovered sensitive plant; and shows that nature may have some view towards its nourishment, in forming the upper joint of its leaf like a machine to catch food. Upon the middle of this lies the bait for the unhappy insect that becomes its prey. Many minute red glands, that cover its inner surface, and which, perhaps, discharge some sweet liquor, tempt the poor animal to taste them; and the instant these tender plants are irritated by its feet, the two lobes rise up, grasp it fast, lock the two rows of spines together, and squeeze it to death. Further, lest the strong efforts for life, in the creature thus taken, should serve to disengage it, three small erect spines are fixed near the middle of each lobe among the glands, that effectually put an end to all its struggles. Nor do the lobes ever open again, while the dead animal continues there. But it is nevertheless certain that the plant cannot distinguish between an animal and a mineral substance; for if we introduce a straw, or a pin, between the lobes, it will grasp it full as fast as if it were an insect. This plant grows in America, in wet shady places, and flowers in July and August. The largest leaves are about three inches long, and an inch and a half across the lobes: the glands of those exposed to the sun are of a beautiful red color; but those in the shade are pale, and inclining to green. The roots are squamous, sending forth few fibres, and are perennial. The leaves are numerous, inclining to bend downwards, and are placed in a circular order; they are jointed and succulent; the lower joint, which is a kind of stalk, is flat, longish, two-edged, and inclining to heart-shaped. In some varieties, they are serrated on the edges near the top. The upper joint consists of two lobes, each lobe is of a semi-oval form, with their margins furnished with stiff hairs, like eye-brows, which
