How curious is the structure of the nest of the Bullfinch or Chaffinch! The inside of it is lined with cotton and fine silken threads; and the outside cannot be sufficiently admired, though it is composed only of various kinds of fine moss. The color of these mosses, resembling that of the bark of the tree in which the nest is built, proves that the bird intended it should not be easily discovered. In some nests, hair, wool, and rushes are cleverly interwoven. In others, the parts are firmly fastened by a thread, which the bird makes of hemp, wool, hair, or, more commonly, of spiders' webs. Other birds--as, for instance, the blackbird and the lapwing--after they have constructed their nests, plaster the inside with mortar; they then stick upon it, while quite wet, some wool or moss to give warmth; but all alike construct their nests so as to add to their security.
In animals like sea-anemones and jellyfishes the general symmetry of the body is radial; that is to say, there is no right or left, and the body might be halved along many planes. It is a kind of symmetry well suited for sedentary or for drifting life. But worms began the profitable habit of moving with one end of the body always in front, and from worms to man the great majority of animals have bilateral symmetry. They have a right and a left side, and there is only one cut that halves the body. This kind of symmetry is suited for a more strenuous life than radial animals show; it is suited for pursuing food, for avoiding enemies, for chasing mates. And _with the establishment of bilateral symmetry must be associated the establishment of head-brains_, the beginning of which is to be found in some simple worm-types.
The figures shown in the dry-paintings are conventionalized representations of the characters in Navaho mythology and of incidents in the myth. With how many such paintings the Navaho medicine-men are familiar is an unanswered question; but more than sixty have been noted, some of them most elaborate. In making them, the ground within the ceremonial hogan is evenly covered with fine brown earth, upon which the figures are drawn with fine sands and earths of many colors allowed to flow between the thumb and the first two fingers. The Navaho become so skilled in this work that they can draw a line as fine as a broad pencil mark. Many of the paintings are comparatively small, perhaps not more than four feet in diameter; others are as large as the hogan permits, sometimes twenty-four feet across. To make such a large painting requires the assistance of all the men who can conveniently work at it from early morning until mid-afternoon.
