Some again call themselves Naturalists, and under the shelter of that high-sounding name occupy themselves in destroying nature. The true naturalist never destroys life without good cause, and when he does so, it is with reluctance, and in the most merciful way; for the life is really the nature, and that gone, the chief interest of the creature is gone too. We should form but a poor notion of the human being were we only to see it presented to our eyes in the mummy; and equally insufficient is the idea that can be formed of an animal from the inspection of its outward frame. Nature and life belong to each other; and, if torn asunder, the one is objectless and the other gone.
Lastly, let me remind those who find such gratification in destroying, that the word “Destroyer” is in the Greek language “Apollyon”.
As we do not intend to treat of the dead and dried bodies of animals, but of their active life, we return to our bat flitting in the evening dusk, and, instead of shooting him, watch his proceedings.
Every creature is made for happiness, and receives happiness according to its capacity; and it is very wrong to suppose that, because we should be miserable if we led the life of a vulture, or a sloth, or a bat, therefore those creatures are miserable. In truth, the vulture is attracted to, and feels its greatest gratification in, those substances which would drive us away with averted eyes and stopped nostrils. The sloth is, on the authority of Waterton, quite a jovial beast, and anything but slothful when in his proper place; and as for the bat, it sings for very joy. True, the song is not very melodious, neither is that of the swift, or the peacock, nor, perhaps, that of the Cochin-China fowl, but it is nevertheless a song from the abundance of the heart.
There are many human ears that are absolutely incapable of perceiving the cry of the bat, so keen and sharp is the note; a very razor’s-edge of sound.
More than once I have been standing in a field over which bats were flying in multitudes, filling the air almost oppressively with their sharp needle-like cries. Yet my companion, who was a musician, theoretically and practically, was unable to hear a sound, and could not for some time believe me when I spoke of the noisy little creatures above.
The sound bears some resemblance to that produced by a slate-pencil when held perpendicularly in writing on the slate, only the bat’s cry is several octaves more acute. I never but once heard the sound correctly imitated, and that was done by a graceless urchin, during a long sermon one Sunday morning. He had contrived to arrange two keys in such a manner that, when grated over each other, they produced a squeaking sound that exactly resembled the cry uttered by the bat. So, by judicious management of his keys, he kept the congregation on the look-out for the bat, and beguiled the time much to his satisfaction.
Of so piercing and peculiar a nature is the cry, that it gives no clue to the position or distance of the creature that utters it, and it seems to proceed indiscriminately from any portion of the air towards which the attention happens to be directed. The note of the grasshopper lark possesses somewhat of the same quality.
Even in confinement the bat is an interesting creature, and discovers certain traits of character and peculiarities of habit which in its wild state cannot be seen. I might here refer to several stories of domesticated and tamed bats; but as they have already been given to the world, and my space is limited, I prefer to give my own experiences.
Not long ago, I received a message from a neighbouring grocer, requesting me to capture a bat which had flown into the shop, and which no one dared touch.
When I arrived, the creature had taken refuge on an upper shelf, and had crawled among a pile of sugar-loaves that were lying on their sides after the usual custom. We pulled out several loaves near the spot where the bat was last seen, and by casting a strong light from a bull’s-eye lantern, discovered a little black object snugly ensconced at the very back of the shelf.
I pushed my hand towards the spot, but for some time could not seize the creature, as it was so tightly packed, and squeezed into a corner. At last the bat gave a flap with one of the wings, which I caught, and so gently drew my prisoner forwards.
He was a brave little fellow, as well as discreet, and bit savagely at my fingers. However, his little tiny teeth could not do much damage, and I put him into a cage which I brought with me.
The cage was originally made for the reception of mice, and was of a rude character—the back and ends being of wood and the front of wire. In a very few minutes after his entrance into the cage, the bat climbed up the wooden back, by hitching his claws into the slight inequalities of the wood, and there hung suspended, head downwards.
When so placed, his aspect was curious enough. The claws of the hind legs being fixed into a crevice, so as to bear the weight of the body, the wings were then extended to their utmost, and suddenly wrapped round the body. At the same time the large ears were folded back under the wings and protected by them, the orifice of the ear itself being guarded in a very singular manner.
If the reader will refer to the figure of the bat on page 4, he will see that inside the great ear is a sharply-pointed membrane, somewhat resembling a second ear. This membrane is called the “tragus,” and when the large ears are tucked away out of sight, the tragus remains exposed, and gives the creature a very strange appearance.
When the bat is living, the ears are of singular beauty. Their substance is delicate, and semi-transparent if viewed against the light; so much so, indeed, that by the aid of a microscope the circulation of the blood can be detected. As the creature moves about, the ears are continually in motion, being thrown into graceful and ever-changing curves. If people only knew what a pretty pet the long-eared bat can become, they would soon banish dormice and similar creatures in favour of bats.
It was rather a remarkable circumstance, that the bat of which I have just been speaking would not touch a fly, although one which I had in my possession some ten years since would eat flies and other insects readily. Whenever it took the insect, it daintily ate up the abdomen and thorax, rejecting the head, wings, and legs. But my second bat entirely refused insects of any kind, and would eat nothing but raw beef cut up into very small morsels. I never had a pet so difficult to feed.
If the meat were not perfectly fresh, or if it were not cut small enough, the bat would hardly look at it. Now if a bit of raw meat about the size of a large pin’s head be placed in the air, a few minutes will dry and harden its exterior; and when this was the case, my bat did not even notice it. So I had to make twenty or more attempts daily before the creature would condescend to take any food.
When, however, it did eat, its mode of so doing was remarkable enough. It seized the meat with a sharp snap, retreated to the middle of the cage, sat upright—as in the engraving already alluded to—thrust its wings forward to form a kind of tent, and then, lowering its head under its wings, disposed of the meat unseen.
From the movement of the neck and upper portion of the head, it would be seen that the creature ate the meat much after the manner of a cat; that is, by a series of snaps or pecks; for the teeth are all sharply pointed, and have no power of grinding the food. These teeth can be seen in the accompanying sketch of a bat’s skull.
In many parts of England the bats are called “Flitter-mice,” and are thought to be simply mice plus wings. This opinion has been formed from the resemblance between the general shape, and especially that of the fur, of the two animals. But if we look at the teeth, we find at once that those of the bat are sharp and pointed, extending tolerably equally all round the jaw-bone; while the teeth of the mice are of that chisel-shaped character found in the rabbit and other rodent animals.
Now if we turn to the fur, and examine it with a microscope, we shall there find characteristics as decided as those of the teeth.
