Commencing with the cases of the forming of the crystals, as spoken of in our last lesson, we may pass on to plant life. But before doing so, it may be well for us to take a parting look at the Will manifesting crystal forms. One of the latest scientific works makes mention of the experiments of a scientist who has been devoting much attention to the formation of crystals, and reports that he has noticed that certain crystals of organic compounds, instead of being built up symmetrically, as is usual with crystals, were "enation-morphic," that is, opposed to each other, in rights and lefts, like hands or gloves, or shoes, etc. These crystals are never found alone, but always form in pairs. Can you not see the Will behind the curtain here? Let us look for the Will in plant-life. Passing rapidly over the wonderful evidences in the cases of the fertilization of plants by insects, the plant shaping its blossom so as to admit the entrance of the particular insect that acts as the carrier of its pollen, think for a moment how the distribution of the seed is provided for. Fruit trees and plants surround the seed with a sweet covering, that it may be eaten by insect and animal, and the seed distributed. Others have a hard covering to protect the seed or nut from the winter frosts, but which covering rots with the spring rains and allows the germ to sprout. Others surround the seed with a fleecy substance, so that the wind may carry it here and there and give it a chance to find a home where it is not so crowded. Another tree has a little pop-gun arrangement, by means of which it pops its seed to a distance of several feet. Other plants have seeds that are covered with a burr or "sticky" bristles, which enables them to attach themselves to the wool of sheep and other animals, and thus be carried about and finally dropped in some spot far away from the parent plant, and thus the scattering of the species be accomplished. Some plants show the most wonderful plans and arrangements for this scattering of the seed in new homes where there is a better opportunity for growth and development, the arrangements for this purpose displaying something very much akin to what we would call "ingenuity" if it were the work of a reasoning mind. There are plants called cockle-burs whose seed-pods are provided with stickers in every direction, so that anything brushing against them is sure to pick them up. At the end of each sticker is a very tiny hook, and these hooks fasten themselves tightly into anything that brushes against it, animal wool, hair, or clothing, etc. Some of these seeds have been known to have been carried to other quarters of the globe in wool, etc., there to find new homes and a wider field.
