Among protophytes it needs but to think of the multitudinous varieties of diatoms and desmids, with their elaborately-constructed coverings; or of the definite methods of growth and multiplication among such simple Algæ as the Conjugatæ; to see that most of their distinctive characters are due to inherited constitutions, which have been slowly moulded by survival of the fittest to this or that mode of life.
Examined a spot one inch in diameter, raised in center, green, found Oedegonium abundant. Some desmids, Cosmarium binoculatum plenty. One or two red Gemiasmas, starch, Protuberans lamella, Pollen. Specimen soft magma of the pool margin. Oedogonium abundant, spores, yeast plants, dirt. Sand scraped. No organized forms but pollen, and mobile spores of some cryptogams. Dew on grass.
Algal spores took hold, desmids and diatoms swam in and settled down, little fish wandered in and out of the crevices, while large ones nosed at the entrances. Then Mother Earth turned slowly onward; the moon, reaching down, beckoned with invisible fingers, and the air again entered this no man's land.
