“Are God and Nature then at strife, That Nature lends such evil dreams? So careful of the type she seems, So careless of the single life.” ——— “And the individual withers, and the world is more and more.” —Tennyson.
FOR some inscrutable reason which she has as yet given no hint of revealing, Nature is wondrously wasteful in the matter of generation. She creates a thousand where she intends to make use of one.
Imbued with the maternal instinct, the female cod casts millions of eggs upon the waters, expecting them to return after many days as troops of interesting {7} offspring. Instead, half die embryotic gadi are almost immediately devoured by spawn-eaters, hundreds of thousands perish in incubation, hundreds of thousands more succumb to the perils attending ichthyic infancy, leaving but a few score to attain to adult usefulness and pass an honored old age with the fragrance of a well-spent life in the country grocery.
The oak showers down 10,000 acorns, each capable of producing a tree. Three-fourths of them are straightway diverted from their arboreal intent through conversion into food by the provident squirrel and improvident hog. Great numbers rot uselessly upon the {8} ground, and the few hundred that finally succeed in germinating grow up into dense thickets, where at last die strongest smothers out all the rest like an oaken Othello in a harem of quercine Desdemonas.
THIS is the law of all life, animal as well as vegetable. From the humble hyssop on the wall to the towering cedar of Lebanon, from the meek and lowly amoeba—which has no more character or individuality than any other pin-point of jelly—to the lordly tyrant {9} man, the rule is inevitable and invariable.
Life is sown broadcast only to be followed almost immediately by a destruction nearly as swift. Nature creates by the million apparently that she may destroy by the myriads. She gives life one instant only that she may snatch it away the next. The main difference is that the higher we ascend the less lavish is the creation and the less sweeping the destruction.
Thus, while probably but one fish out of a thousand reaches maturity, of 1,000 children born 604 attain adult age; that is, Nature flings aside 999 out of every 1,000 fish as useless for {10} her purposes, and two out of every five human beings.
MANY see in this relentless weeding out and destruction of her inferior products a remarkable illustration of the wisdom of Nature’s methods. What would they thin
