They seemed to use six notes, these notes being repeated in melodious sequences. I noticed, several times, a run of four notes in ascending scale. On another occasion, in my bedroom, I heard a mouse sing his pleasing little song over and over again.

Miss Ada Sterling, editor of _Fashions_, writes me as follows:--

"... Anent your paper ... I have had some curious experiences of a similar nature; one was in an uncarpeted room, the house being deserted at that time. I stood still, planning certain things and humming softly to myself. Presently, a shadowy something caught my eye, and I discovered a little mouse, very young evidently, then another and another, until four were near. I did not attribute their tameness to music, and in surprise turned to see if there were others about.

Instantly they scampered off, my action having frightened them.

"When I finally arrived at the conclusion that music had attracted them, I sat down and began to hum, this time with an open sound instead of a closed tone, and in a second the little creatures were out again, standing perfectly still, as if the sound gave them delight. Gradually I swelled the tone, and yet they were undisturbed until I became too bold and gave a clear, sharp, full sound, and this at once frightened them.

"_I experimented in this way for more than a month, never missing my audience once_, and by this time the little creatures, grown so fat and bold as to cause serious damage, were ruthlessly caught and killed.

"I heard Kate Field, about four years ago, when, as the guest of Mr.

Stedman, she told several interesting stories, relate an experience of her own, wherein, one night early in her life, she had leaned against the walls of the Campanile, gray and phantom-like in the moonlight, and, singing softly to herself, was surprised at discovering several little lizards lying about on the stones, their heads held alertly in the air as if entranced by the sound of her voice. She, too, experimented with the varying sounds, and from time to time, and evidently looked back upon the experiment as one of rare interest to herself."

Tree lizards will listen completely entranced to the music of a good whistler, and will allow themselves to be captured while thus inthralled. Some lizards are fairly good musicians themselves, notably the tree lizards of the East Tennessee mountains. I have repeatedly heard them singing on the slopes of Chilhowie and adjacent peaks.

Burroughs writes very entertainingly of a singing lizard, or, rather, salamander: "... Approach never so cautiously the spot from which the sound proceeds and it instantly ceases, and you may watch for an hour without hearing it again. 'Is it a frog,' I said--'the small tree-frog, the piper of the marshes--repeating his spring note but little changed amid the trees?' Doubtless it is, but I must see him in the very act. So I watched and waited, but to no purpose, till one day, while bee-hunting in the woods, I heard the sound proceeding from the leaves at my feet.

Keeping entirely quiet, the little musician presently emerged, and lifting himself up on a small stick, his throat palpitated, and the plaintive note again came forth. 'The queerest frog that ever I saw,'

said a youth who accompanied me and whom I had enlisted to help solve the mystery. No, it was no frog or toad at all, but the small red salamander commonly called lizard."[64]

[64] Gibson, _Sharp Eyes_, pp. 105, 106; quotation.

The sound of the piccolo is very pleasing to these little creatures, and I have frequently collected about me as many as ten or a dozen by sounding this instrument in the still depths of a wood which I knew these salamanders frequented.

Certain snakes are very susceptible to the charm of harmonious tonal vibration; witness the performance of the Hindu snake charmer, who, while handling that deadly poisonous creature, the cobra-de-capello, plays continuously on flageolets, fifes, or other musical instruments.[65] I, myself, have often held tree lizards completely entranced until grasped in my hand, by whistling shrilly and continuously.

[65] It has been claimed by some that the cobra is not influenced by the music, but by movements of the Hindu performer, who dances, salaams, etc., continually while giving exhibitions. Very recently, however, Momsen has proven the contrary by actual experiment.

I remember, on one occasion, when I was quite young, that a large black snake crawled through a ventilating hole in the wall of the "quarters"

or row of brick cottages occupied by the negroes, and took shelter beneath the floor. It was seen by myself and some of my dusky playmates, who immediately carried the tidings to the negro gardener. He called one of the hands from the field, and, after placing him with a loaded shotgun at one side of the hole in the wall, took his station just behind him and commenced to play on his fiddle. In a few moments the snake came out, and was killed by the discharge of the gun in the hands of the other negro. I have been informed, time and again, by negroes that they could charm snakes from their holes with music, but the instance related above is the only one of the snake being led to its death by the bewitching power of musical sounds that has ever come under my immediate personal observation.

Before dismissing the subject of the influence of music on animals, I wish to call attention to the fact that Romanes declares that pigeons and parrots evince an aesthetic enjoyment of musical sounds.

"Moreover," writes he, "the pleasure which birds manifest in musical sounds is not always restricted to the sounds which they themselves produce."

Bingley quotes John Lockman, the celebrated composer, who declares that he once saw a pigeon which could distinguish a particular air. Lockman was visiting a Mr. Lee in Cheshire, whose daughter was a fine pianist, "and whenever she played the air of _Speri si_ from Handel's opera of 'Admetus,' a pigeon would descend from an adjacent dovecot to the window of the room where she sat, 'and listen to the air apparently with the most pleasing emotions,' always returning to the dovecot immediately the air was finished. But it was only this one air that would induce the bird to behave in this way."[66]

[66] Romanes, _Animal Intelligence_, p. 282; quoted by Bingley, _Animal Biography_, Vol. II. p. 220.

A correspondent writes me that he has a c.o.c.k which is pa.s.sionately fond of the sound of the violin. This bird always flies to the window of the music-room as soon as he hears the sound of the violin, where he will quietly remain perched as long as the music continues. As soon as the music ceases, he flies down from the window.

Horses very frequently show an appreciation for musical sounds, especially when they are produced by a band of bra.s.ses.

Amus.e.m.e.nt and pastime are, unquestionably, aesthetic psychical characteristics, hence, when we see evidences of these mental operations, we must acknowledge the presence of aestheticism in the animals in which they are to be noticed.

I propose to show that animals low in the scale of life--animals so low and so minute that it takes a very high-power lens to make them visible, have their pastimes and amus.e.m.e.nts. Also, that many insects and even the slothful snail are not so busily engaged in the struggle for existence that they cannot spare a few moments for play. In our researches in this field of animal intelligence we must not attribute the peculiar actions of the males in many species of animals when courting the females, to simple pastime, for they are the outward manifestations of s.e.xual desire, and are not examples of psychical amus.e.m.e.nt. I have seen, in actinophorous rhizopods, certain actions, unconnected with s.e.xual desire or the gratification of appet.i.te, which lead me to believe that these minute microscopic organisms have their pastimes and moments of simple amus.e.m.e.nt. On several occasions while observing these creatures, I have seen them chasing one another around and around their miniature sea.

They seemed to be engaged in a game of tag. This actinophrys is not very agile, but when excited by its play, it seems to be an entirely different creature, so lively does it become. These actions were not those of strife, for first one and then another would act the pursuer and the pursued. There were, generally, four or five actinophryans in the game.

One of the rotifers frequently acts as if engaged in play. On several occasions I have observed them perform a kind of dance, a _pas seul_, for each rotifer would be alone by itself. Their motions were up and down as if exercising with an invisible skipping-rope. They would keep up this play for several minutes and then resume feeding or quietly remain at rest. This rotifer goes through another performance which I also believe to be simply a pastime. Its tail is armed with a double hook or forceps. It attaches itself to a piece of alga or other substance by this forceps, and then moves its body up and down in the water for several minutes at a time.

The snail (_H. pomatia_) likewise has its moments of relaxation and amus.e.m.e.nt. The following instance of play may be considered to be gallantry by some, but I do not believe that I am mistaken, however, when I consider it an example of animal pastime. Two snails approached each other, and, when immediately opposite, began slowly to wave their heads from side to side. They then bowed several times in courtly salutation. This performance they kept up for quite a while and then moved away in different directions. At no time did they come in contact, and careful observation failed to reveal any excitement in the genitalia. I have witnessed the embraces of snails, and the performance described above does not resemble, in the slightest degree, the manoeuvres executed at such times by mating individuals.

Swarms of Diptera may be seen on any bright day dancing in the sunlight.

Naturalists have heretofore considered this swarming to be a mating of the two s.e.xes. This is not the case, however, in many instances. On numerous occasions, and at different seasons of the year, I have captured dozens of these insects in my net and have examined them microscopically. I found them all to be unimpregnated females; I have never yet discovered a male among them. In some of the Diptera the males emerge from the pupa state after the females; I therefore believe that the females await the presence of the males, and, while waiting, pa.s.s the time away in aerial gambols.

Forel, Lubbock, Kirby, Spence, and other naturalists have declared that ants, on certain occasions, indulge in pastimes and amus.e.m.e.nts. Huber says that he saw a colony of _pratensis_, one fine day, "a.s.sembled on the surface of their nest, and behaving in a way that he could only explain as simulating festival sports or other games."[67] On the 27th of September last, the males and females of a colony of _Lasius flavus_ emerged from their nest; I saw these young kings and queens congregate about the entrance of the nest and engage in playful antics until driven away by the workers. The workers would nip their legs with their mandibles until the royal offspring were forced to fly in order to escape being bitten. The inciting cause of these movements may have been s.e.xual in character, but I hardly think so.

[67] Buchner, _Geistesleben der Thiere_, p. 163; quoted also by Romanes, _loc. cit. ante_, pp. 87, 88.

On the 19th of July, 1894, I saw several _Lasius niger_ come out of their nest accompanied by a minute beetle (_Claviger foveolatus_); the ants caressed and played with this little insect for some time, and then conducted it back into the nest.[68]

[68] On one occasion several years ago, I saw a number of young ants of _L. niger_ brought out of the nest by five or six old ants, which watched over the young and kept them from straying away. The young ants played about the nest entrance for some time, and were then conducted back into the hive by the old ants.--W.

Many such little animals are kept by the ants as pets. Lubbock says of one of them, a species allied to _Podura_, and for which he proposes the name _Beckia_, "It is an active, bustling, little being, and I have kept hundreds, I may say thousands, in my nests. They run in and out among the ants, keeping their antennae in a perpetual state of vibration."[69]

I have frequently noticed an insect belonging to the same genus as the above in the nests of _F. fusca_ and _F. rufescens_. They reminded me very much of the important-looking little dogs one sees running about in the crowd on election day.

[69] Lubbock, _Ants, Bees, and Wasps_, p. 74.

The females of _Coccinellae_ ("lady-bugs") frequently congregate and indulge in performances that cannot be anything else save pastimes. A beech tree in my yard is called "lady-bug tree" because, year after year, these insects collect there and hold their curious conventions.

They caress one another with their antennae, and gently "shoulder" one another from side to side. Sometimes several will get their heads together, and seem by their actions to be holding a confidential conversation.

These conventions always take place after oviposition, and careful and repeated observation has shown me that they are not connected with procreation or alimentation. I have witnessed many other instances of true psychical amus.e.m.e.nt in the lower animals, but do not think it is necessary to detail them here. Suffice it to say that I believe that almost every living creature, at some period of its existence, has its moments of relaxation from the cares of life, when it enjoys the gratification of amus.e.m.e.nt.

Some birds evince aesthetic taste, notably in the building of their nests, which they ornament and decorate in a manner very pleasing to the eye.

The snakeskin bird gets its name from its habit of using the cast-off skins of snakes for decorative purposes. Not long ago I found a nest in a small wood, not far from the town in which I live, which was beautifully ornamented with the exuviated skin of a black snake (_Bascanion constrictor_). This skin must have been at least five feet in length, and the little artists had woven it into the walls of their nest in such a manner that its translucent, glittering scales contrasted very beautifully with the darker materials of their home.

Humming-birds use bits of lichen and moss to decorate their tiny nests.

These materials serve a twofold purpose: they not only render the nest beautiful, but they also serve to protect it by making it resemble the limb on which it is placed. It takes a very acute and discriminating eye, indeed, to locate a humming-bird's nest.

Probably of all the lower animals, the male satin or bower bird of New South Wales has the decorative feeling the most developed. This bird builds a pleasure resort, a summer-house, or, rather, dance hall, which he ornaments profusely with every glittering, shining, striking object that he can carry to his bower in the depths of the forest. This bower is built of twigs, and, when completed, is an oblong, sugar-loaf-like structure, open at both ends. The bird decorates his dancing hall (for he comes here to perform love-dances during the courting season) with bright-colored rags, sh.e.l.ls, pebbles, bones, etc.

I once saw a pair of bower birds in captivity (they were owned by Mr.

George Hahn of St. Louis), which constructed the dance hall from materials furnished by their owner.

The love of personal cleanliness is, probably, the root and beginning of much that is aesthetic among the lower animals.

When quite a small lad, one of the first lessons set down in my copy-book, after I had graduated in "pot-hooks and hangers," was the trite old saw, "Cleanliness is next to G.o.dliness." My Yankee governess, a tall, angular spinster, from Maine, made the meaning of this copy clear to my infant mind, pointing her remarks by calling attention to the Kentucky real estate which had found a resting-place beneath my finger-nails, and which seemed to decorate them with perpetual badges of mourning. I have never forgotten that lesson and firmly believe in its truth.

The love of cleanliness seems to be inherent in the lower animals, with but few exceptions. We have all noticed the cat, the dog, the squirrel, the monkey, and the birds at toilet-making; and we know that they spend a large portion of their time in cleansing and beautifying their bodies.

Some of them are dependent on their own ministrations, while others are greatly a.s.sisted by humble little servants, whose only remuneration is domicile, the cast-off clothing, or the garbage and refuse from their host's table.

For instance, the common domestic fowl is greatly a.s.sisted in its toilet by certain little animals belonging to the family _Liothe_. These little creatures carefully sc.r.a.pe away and eat the scarf-skin, and other epidermal debris that would otherwise impair the health of their hosts.[70] Some of the fish family are entirely dependent on the ministrations of mutualists, as these little hygienic servitors are called, in matters of the toilet. Notably, the gilt catfish, which would undoubtedly die if deprived of its mutualist, the _Gyropeltes_. This remarkable little creature does not live on the body of its host, but swims free in the water, and only seeks him when it is hungry. The skin of the gilt catfish secretes a thick, glairy, mucous exudate, which, if left to itself, would imperil the health of the fish. The Gyropeltes, however, regards this exudate as delicious food and rapidly removes and devours it.

[70] Van Beneden, _Animal Parasites and Messmates_, pp. 71, 72.

All insects devote some of their time to the toilet, and there is probably no one who has not, at some time or other, noticed the fly, or some other insect, thus engaged. The greatest lover of bodily cleanliness in the whole insect tribe, however, is, I believe, my pet locust, "Whiskers"--so named by a little niece, on account of her long, graceful antennae. "Whiskers" is one of the smallest of her family, and is a dainty, lovely, agile little creature, light olive-green in color, with red legs. She was reared from the egg, and has lived in my room all her short life. She is quite tame and recognizes me as soon as I approach, often hopping two feet or more in order to light on my coat-sleeve or outstretched hand.[71]

[71] Shortly after the above was written, this interesting little creature met an untimely fate at the hands of an Irish chambermaid, who was a recent importation and who did not understand that all life was held sacred in my house.--W.
