Beside the life tree behold its complement the death plant of Java, called by the Javanese the kali-mujah. This is a beautiful plant, growing nearly four feet high, with long, slender stems having upon them thorns an inch in length. These stems are crowded with broad leaves, thick, smooth as satin, heart-shaped, on one side a delicate emerald green, and on the other a vivid crimson marked with cream-color. From the midst of the leaf-stems rise the flower scapes, well guarded about the blossom with fine, briar-like thorns. The blossoms are milk-white, about the size and shape of a large cup. These beautiful flowers pour out a strong perfume, which, though agreeable, is overpowering and has poisonous qualities. If persons inhale this fragrance for several minutes, they become faint, and then unconscious; if shut up with the plant in a close room even a strong man would soon die. Insects that hover about the flower fall dead, and birds that come, attracted by its red, white, and green splendors, wheel dizzily about it and drop unconscious. Even at a distance of three feet the breath of the kali-mujah will kill a bird or insect, and will give a man a severe headache with convulsive twitching of the muscles of the face. Other plants seem to avoid the kali-mujah, for none will grow in its vicinity. But here is a more cheerful specimen. It should be the joy of all boys,--the whistling tree from Nubia. Day and night, year in and year out, this merry tree whistles tunes of its own composing--chorister of trees! The leaves and stems are so constructed that this tree becomes a shrill musical instrument, whistling loud and clear, even when no wind seems to be stirring. We have all noticed the shiver and murmur in a grove of pines, even in the hot stillness of a summer noontide; the whistling tree like the pine never ceases its peculiar music. Our next wonder plant grows in water; it is a cousin of our white pond-lily, it is the _Victoria regia_ which grows in still pools in the Amazon region. The leaves are round, and are from six to eight feet in diameter. They are sharply turned up at the edge to form a rim, so that each leaf is like a plate, the under surface is crimson, the upper surface green with fine lines; on this elegant plate the flower lies.
