(4) The same kind of imagery is still current in Europe. German authorities tell us about the ‘Wetterbaum,’ which in some places is called ‘Abraham’s Tree,’ in others, ‘Adam’s Tree.’ The Yggdrasill myth is supposed to have the same origin. The Rainbow is the heavenly Mountain Ash of a well known Swedish and Esthonian riddle. The water from heaven was supposed in Egypt to be especially refreshing for the dead

(31) Professor Bieser says: "Another plant showing irritability when touched, and possessing the faculty of finding and raising water by means of a long, slender, flat stem or tube, is a variety of orchid discovered by E. A. Suverkrop, of Philadelphia, several years ago. This plant grows upon the trunks of trees hanging over swampy places along the bank of the Rio de la Plata and streams of the neighborhood. When this orchid is in want of water, the slender stem gradually unwinds until it dips into the water. Then the stem slowly coils around and winds up to discharge upon the part of the plant from which the roots spring the water which it has sucked up into its hollow space or tube within its interior. Sometimes when water is absent from directly under this plant, the stem moves first in this direction and then in another, in its search for water, and finally finding the water it performs the process above described. If this plant is touched while the stem is extended it acts much like the sensitive plant (mimosa), and the stem coils up into a spiral more rapidly than when it is lifting water." The experiments of that wizard of plant-life, Luther Burbank, give us many illustrations of the manner in which the "mind" in the plant will respond to changed environment, and to take advantage of improved conditions thereof in the direction of adapting itself thereto. No one can study the works of modern botanists, or work long among plants, without discovering for himself many facts serving to prove that there is not only Life among the plants, but also sufficient mind to serve the purposes and needs of the existence of the plant. Some scientists have thought it possible that by changing the environment of the plant sufficiently, in the direction of calling out latent possibilities of mental action, it is probable that plants may be evolved which would approach in their mental activity that of the lower forms of animal life, if not indeed exceed the latter.

(27) Many students are doubtless familiar with the instance of the "sensitive plants" which exhibit a marked degree of sensibility to touch. Many insect-eating plants manifest an equally high degree of sensitiveness, though of course in a different direction. The leaves of the Venus' Fly Trap fold upon each other and thus capture the unfortunate insect which has been tempted into the trap by the sweet juice which appears upon the leaf as a dainty bait. The folding of the leaves follows the alarm given by the three sensitive bristles or hairs which act as feelers which sense the presence of the insects. Bits of earth, or raindrops, are recognized as "not-food" by these feelers, and no closing of leaves result from their presence on the leaves. Other plants are very sensitive to degrees of light, and they close at certain hours, the time varying according to the species of the plant. It was formerly held that this sensitiveness to light was merely a chemical response to the presence of light, but recent experiments have shown that such plants, when placed in a dark room, will continue this closing for several days, in a gradually lessening degree, thus indicating the presence of a "habit" within their consciousness, which "habit" indicates the presence of "mind" even more forcibly than does the closing itself. Certain ferns will wither if their fronds are touched too often.
