This particular cow of my neighbor’s that I hear lowing, is an entirely gentle creature ordinarily, but with a calf at her side she will pitch at any one who approaches her. And there is no other cow in the herd that mourns so long after her calf. The mother in her is stronger, more enduring, than in any of the other nineteen cows in the barn. My own cow hardly mourns at all when her calf is taken away. She might be an oak tree losing its acorns, or a crab losing her hatching eggs, so far as any show of love is concerned.
The female crab attaches her eggs to her swimmerets and carries them about with her for their protection as the most devoted of mothers; yet she is no more conscious of them, and feels no more for them, than the frond of a cinnamon fern feels for its spores. She is a mother, without the love of the mother.
In the spider, however, just one step up the animal scale from the crab, you find the mother-love or passion. Crossing a field the other day, I came upon a large female spider of the hunter family, carrying a round white sack of eggs, half the size of a cherry, attached to her spinnerets. Plucking a long stem of grass, I detached the sack of eggs without bursting it. Instantly the mother turned and sprang at the grass-stem, fighting and biting until she got to the sack, which she seized in her strong jaws and made off with as fast as her long, rapid legs would carry her.
I laid the stem across her back and again took the sack away. She came on for it, fighting more fiercely than before. Once more she seized it; once more I forced it from her jaws, while she sprang at the grass-stem and tried to tear it to pieces. She must have been fighting for two minutes when, by a regrettable move on my part, one of her legs was injured. She did not falter in her fight. On she rushed for the sack as fast as I pulled it away. She would have fought for that sack, I believe, until she had not one of her eight legs to stand on, had I been cruel enough to compel her. It did not come to this, for suddenly the sack burst, and out poured, to my amazement, a myriad of tiny brown spiderlings. Before I could think what to do that mother spider had rushed among them and caused them to swarm upon her, covering her, many deep, even to the outer joints of her long legs. I did not disturb her again, but stood by and watched her slowly move off with her encrusting family to a place of safety.
I had seen these spiders try hard to escape with their egg-sacks before, but had never tested the strength of their purpose. For a time after this experience I made a point of taking the sacks away from every spider I found. Most of them scurried off to seek their own safety; one of them dropped her sack of her own accord; some of them showed reluctance to leave it; some of them a disposition to fight; but none of them the fierce, consuming mother-fire of the one with the hurt leg.
Among the fishes, much higher animal forms than the spiders, we find the mother-love only in the males. It is the male stickleback that builds the nest, then goes out and drives the female in to lay her eggs, then straightway drives her out to prevent her eating them, then puts himself on guard outside the nest to protect them from other sticklebacks and other enemies, until the young shall hatch and be able to swim away by themselves. Here he stays for a month, without eating or sleeping, so far as we know.
It is the male toadfish that crawls into the nest-hole and takes charge of the numerous family. He may dig the hole, too, as the male stickleback builds the nest. I do not know as to that. But I have raised many a stone in the edge of the tide along the shore of Naushon Island in Buzzard’s Bay, to find the under surface covered with round, drop-like, amber eggs, and in the shallow cavity beneath, an old male toadfish, slimy and croaking, and with a countenance ugly enough to turn a prowling eel to stone. The female deposits the eggs, glues them fast with much nicety to the under surface of the rock, as a female might, and finishes her work. Departing at once, she leaves the coming brood to the care of the male, who from this time, without relief or even food in all probability, assumes the rôle and all the responsibilities of mother, and must consequently feel all the mother-love.
Something like this is true of the common hornpout, or catfish, I believe, though I have never seen it recorded, and lack the chance at present of proving my earlier observations. I think it is father catfish that takes charge of the brood, of the swarm of kitten catfish, from the time the spawn is laid.
