IN studying Nature, the important thing is not so much what we see as how we interpret what we see. Do we get at the true meaning of the facts? Do we draw the right inference? The fossils in the rocks were long observed before men drew the right inference from them. So with a hundred other things in nature and life.

During May and a part of June of 1903, a drouth of unusual severity prevailed throughout the land. The pools and marshes nearly all dried up. Late in June the rains came again and filled them up. Then an unusual thing happened: suddenly, for two or three days and nights, the marshes about me were again vocal with the many voices of the hyla, the “peepers” of early spring. That is the fact. Now, what is the interpretation? With me the peep­ers become silent in early May, and, I suppose, leave the marshes for their life in the woods. Did the drouth destroy all their eggs and young, and did they know this and so come back to try again? How else shall one explain their second appearance in the marshes? But how did they know of the destruction of their young, and how can we account for their concerted action? These are difficulties not easily overcome. A more rational explanation to me is this, namely, that the extreme dryness of the woods — nearly two months without rain — drove the little frogs to seek for moisture in their spring haunts, where in places a little water would be pretty certain to be found. Here they were holding out, probably hibernating again, as such creatures do in the tropics during the dry season, when the rains came, and here again they sent up their spring chorus of voices, and, for aught I know, once more deposited their eggs. This to me is much more like the ways of Nature with her creatures than is the theory of the frogs’ voluntary return to the swamps and pools to start the season over again.

The birds at least show little or no wit when a new problem is presented to them. They have no power of initiative. Instinct runs in a groove, and cannot take a step outside of it. One May day we started a meadowlark from her nest. There were three just hatched young in the nest, and one egg lying on the ground about two inches from the nest. I suspected that this egg was infertile and that the bird had had the sense to throw it out, but on ex­amination it was found to contain a nearly grown bird. The inference was, then, that the egg had been accidentally carried out of the nest some time when the sitting bird had taken a sudden flight, and that she did not have the sense to roll or carry it back to its place.

There is another view of the case which no doubt the sentimental “School of Nature Study” would eagerly adopt: A very severe drouth reigned through­out the land; food was probably scarce, and was becoming scarcer; the bird foresaw her inability to care for four young ones, and so reduced the possible number by ejecting one of the eggs from the nest. This sounds pretty and plausible, and so credits the bird with the wisdom that the public is so fond of believing it possesses. Something like this wisdom often occurs among the hive bees in seasons of scarcity; they will destroy the unhatched queens. But birds have no such foresight, and make no such calculations. In cold, backward seasons, I think, birds lay fewer eggs than when the season is early and warm, but that is not a matter of cal­culation on their part; it is the result of outward conditions.

A great many observers and nature students at the present time are possessed of the notion that the birds and beasts instruct their young, train them and tutor them, much after the human man­ner. In the familiar sight of a pair of crows for­aging with their young about a field in summer, one of our nature writers sees the old birds giving their young a lesson in flying. She says that the most important thing that the elders had to do was to teach the youngsters how to fly. This they did by circling about the pasture, giving a peculiar call while they were followed by their flock — all but one. This was a bobtailed crow, and he did not obey the word of command. His mother took note of his disobedience and proceeded to discipline him. He stood upon a big stone, and she came down upon him and knocked him off his perch. “He squawked and fluttered his wings to keep from falling, but the blow came so suddenly that he had not time to save himself, and he fell flat on the ground. In a minute he clambered back upon his stone, and I watched him closely. The next time the call came to fly he did not linger, but went with the rest, and so long as I could watch him he never disobeyed again.” I should interpret this fact of the old and young crows flying about a field in summer quite differ­ently. The young are fully fledged, and are already strong flyers, when this occurs. They do not leave the nest until they can fly well and need no tutor­ing. What the writer really saw was what any one may see on the farm in June and July: she saw the parent crows foraging with their young in a field. The old birds flew about, followed by their brood, clamorous for the food which their parents found. The bobtailed bird, which had probably met with some accident, did not follow, and the mother re­turned to feed it; the young crow lifted its wings and flapped them, and in its eagerness probably fell off its perch; then when its parent flew away, it followed.

I think it highly probable that the sense or fac­ulty by which animals find their way home over long stretches of country, and which keeps them from ever being lost as man so often is, is a faculty entirely unlike anything man now possesses. The same may be said of the faculty that guides the birds back a thousand miles or more to their old breeding-haunts. In caged or housed animals I fancy this faculty soon becomes blunted. President Roosevelt tells in his “Ranch Life” of a horse he owned that ran away two hundred miles across the plains, swimming rivers on the way to its old home. It is very certain, I think, that this homing feat is not accomplished by the aid of either sight or scent, for usually the returning animal seems to follow a comparatively straight line. It is, or seems to be, a consciousness of direction that is as unerring as the magnetic needle. Reason, calculation, and judgment err, but these primary instincts of the animal seem almost infallible.

In Bronx Park in New York a grebe and a loon lived together in an inclosure in which was a large pool of water. The two birds became much at­tached to each other and were never long separated. One winter day on which the pool was frozen over, except a small opening in one end of it, the grebe dived under the ice and made its way to the far end of the pool, where it remained swimming about aimlessly for some moments. Presently the loon missed its companion, and with an apparent look of concern dived under the ice and joined it at the closed end of the pool. The grebe seemed to be in distress for want of air. Then the loon settled upon the bottom, and with lifted beak sprang up with much force against the ice, piercing it with its dagger-like bill, but not breaking it. Down to the bottom it went again, and again hurled itself up against the ice, this time shattering it and rising to the surface, where the grebe was quick to follow, Now it looked as if the loon had gone under the ice to rescue its friend from a dangerous situation, for had not the grebe soon found the air, it must have perished, and persons who witnessed the incident interpreted it in this way. It is in such cases that we are so apt to read our human motives and emo­tions into the acts of the lower animals. I do not suppose the loon realized the danger of its com­panion, nor went under the ice to rescue it. It fol­lowed the grebe because it wanted to be with it, or to share in any food that might be detaining it there, and then, finding no air-hole, it proceeded to make one, as it and its ancestors must often have done before. All our northern divers must be more or less acquainted with ice, and must know how to break it. The grebe itself could doubtless have broken the ice had it desired to. The birds and the beasts often show much intelligence, or what looks like intelligence, but, as Hamerton says, “the mo­ment we think of them as human, we are lost.”

A farmer had a yearling that sucked the cows. To prevent this, he put on the yearling a muzzle set full of sharpened nails. These of course pricked the cows, and they would not stand to be drained of their milk. The next day the farmer saw the year­ling rubbing the nails against a rock in order, as he thought, to dull them so they would not prick the cows! How much easier to believe that the beast was simply trying to get rid of the awkward incumbrance upon its nose. What can a calf or a cow know about sharpened nails, and the use of a rock to dull them? This is a kind of outside knowledge — outside of their needs and experi­ences — that they could not possess.

An Arizona friend of mine lately told me this interesting incident about the gophers that infested his cabin when he was a miner. The gophers ate up his bread. He could not hide it from them or put it beyond their reach. Finally, he bethought him to stick his loaf on the end of a long iron poker that he had, and then stand up the poker in the middle of his floor. Still, when he came back to his cabin, he would find his loaf eaten full of holes. One day, having nothing to do, he concluded to watch and see how the gophers reached the bread, and this was what he saw: The animals climbed up the side of his log cabin, ran along one of the logs to a point opposite the bread, and then sprang out sidewise toward the loaf, which each one struck, but upon which only one seemed able to effect a lodgment. Then this one would cling to the loaf and act as a stop to his fellows when they tried a second time, his body affording them the barrier they required. My friend felt sure that this leader deliberately and consciously aided the others in securing a footing on the loaf. But I read the incident differently. This successful jumper aided his fellows without designing it. The exigencies of the situation com­pelled him to the course he pursued. Having ef­fected a lodgment upon the impaled loaf, he would of course cling to it when the others jumped so as not to be dislodged, thereby, willy nilly, helping them to secure a foothold. The cooperation was in­evitable, and not the result of design.

The power to see straight is the rarest of gifts; to see no more and no less than is actually before you; to be able to detach yourself and see the thing as it actually is, uncolored or unmodified by your own sentiments or prepossessions. In short, to see with your reason as well as with your perceptions, that is to be an observer and to read the book of nature aright.
