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."
