They certainly have characters which ally them with both. Their very common power of active independent motion and their common habit of living upon complex bodies for foods are animal characters, and have lent force to the suggestion that they are true animals. But their general form, their method of growth and formation of threads, and their method of spore formation are quite plantlike.
Every flower of the field, every blade of grass, every stream that mirrors the heavens above her, every mountain top from which she points an index finger, every breeze in which she whispers, and every cataract in which she speaks, all proclaim the power, the wisdom, the goodness of God the source of all life in the universe, from the minutest spore to all-inventive, soul-endowed man.
The part used for food is the INVOLUCEN SPORANGIUM, or spore case, with its contained spores, which is of an oval shape, flattened, and about one-eighth of an inch in its longest diameter; hard and horny in texture, requiring considerable force to crush or pound it when dry, but becoming soft and mucila ginous when exposed to moisture.
As with the seeds of plants and trees, these spores never had an existence, and never could have had one, before the first independent fungus appeared to produce them. The fungus before the spore is the inevitable induction. No distinction between necessary and contingent truth can ever take a stronger hold than this on the human mind.
The leaf, if badly infected, may not reach full size; it may curl; it may die and fall; the tree thereby is injured. From the fungus in the active diseased areas, another kind of spore develops rapidly. It is the summer-spore, which may be produced in prodigious numbers, and being discharged carries the disease elsewhere. All summer the process of spore-formation and distribution keeps up.
Having traced spore to the entrance of one of these tunnels, my friend crawled in first with his rifle, immediately after him coming a native shikarri, who thrust forward over my friend's back a long bamboo bearing at the end a lighted torch.
The term arthrospores has been given to them to indicate that they are formed as joints or segments, and this term may be a convenient one to retain although the bodies in question are not true spores. Still a different method of spore formation occurs in a few peculiar bacteria. The spores thus formed may not be all alike, differences in size being noticed.
The method of spore formation is always uniform for any single species. Whatever be the method of the formation of the spore, its purpose in the life of the bacterium is always the same. It serves as a means of keeping the species alive under conditions of adversity. Its power of resisting heat or drying enables it to live where the ordinary active forms would be speedily killed.
He put the block no longer frosted in the culture microscope and saw its enclosed, infinitesimal particles of life in the process of multiplying on the food that had been frozen with them when they were reduced to the spore condition. He beamed. He replaced the block in the incubation oven and faced the day cheerfully. Maril greeted him with great reserve.
The difference between the minute, rapidly-formed, and self-moving spore of a conferva, and the slowly-developed seed of a tree, with its multiplied envelopes and large stock of nutriment laid by to nourish the germ during its first stages of growth, illustrates this law in its application to the vegetal world.
