This sentimental view of animal life has its good side and its bad side. Its good side is its result in making us more considerate and merciful toward our brute neighbors; its bad side is seen in the degree to which it leads to a false interpretation of their lives. The tendency to which I refer is no doubt partly the result of our growing humanitarianism and feeling of kinship with all the lower orders of creation, and partly due to the fact that we live in a time of impromptu nature study, when birds and plants and trees are fast becoming a fad with half the population, and when the "yellow" reporter is abroad in the fields and woods. Never before in my time have so many exaggerations and misconceptions of the wild life about us been current in the popular mind. It is becoming the fashion to ascribe to the lower animals nearly all our human motives and attributes, and often to credit them with plans and devices that imply reason and a fair amount of mechanical knowledge. An illustration of this is the account of the nest of a pair of orioles, as described in the "North American Review" for May, 1903, by a writer of popular nature books. These orioles built a nest so extraordinary that it can be accounted for only on the theory that there _is_ a school of the woods, and that these two birds had been pupils there and had taken an advanced course in Strings. Among other things impossible for birds to do, these orioles tied a knot in the end of a string to prevent its fraying in the wind! If the whole idea were not too preposterous for even a half-witted child to believe, one might ask, What in the name of anything and everything but the "Modern School of Nature Study" do orioles know about strings fraying in the wind and the use of knots to prevent it? They have never had occasion to know; they have had no experience with strings that hang loose and unravel in the wind. They often use strings, to be sure, in building their nests, but they use them in a sort of haphazard way, weaving them awkwardly into the structure, and leaving no loose ends that would suffer by fraying in the wind. Sometimes they use strings in attaching the nest to the limb, but they never knot or tie them; they simply wind them round and round as a child might. It is possible that a bird might be taught to tie a knot with its foot and beak, though I should have to see it done to be convinced. But the orioles in question not only tied knots; they tied them with a "reversed double hitch, the kind that a man uses in cinching his saddle"! More wonderful still, not finding in a New England elm-embowered town a suitable branch from which to suspend their nest, the birds went down upon the ground and tied three twigs together in the form of "a perfectly measured triangle" (no doubt working from a plan drawn to a scale). They attached to the three sides of this framework four strings of equal length (eight or ten
