Because the various creatures which God has created have different modes of life, and the forms of their bodies will be found to present a perfect adaptation to the lives allotted to them. Because, also, the beauty of creation depends upon the variety of objects of which it consists. And the greatness of the Creator's power is shown by the diversity of ends accomplished by different means. Because they require a high degree of warmth, on account of the activity of their muscles; but in providing that warmth it was necessary that their coats should be of the lightest material, so as not to impair their powers of flight; and feathers combine the highest warming power, with the least amount of weight. Because, having long legs, they do not require their wings for flight; they are merely used to steady their bodies while running. Because, as the feathers are not employed for flight, the strength of the feather as constructed for flying is unnecessary, and the feathers therefore consist chiefly of a soft down. Because such feathers keep the body of the bird warm and dry, by repelling the water from their surface. A bird could scarcely move through the water, with the downy feathers of the ostrich, because of the amount of water the down would absorb. Because man is the only animal that can clothe itself. As in "Who teacheth us more than the beasts of the earth, and maketh us wiser than the fowls of heaven?"—Job xxxv. Because the creator has thus provided for the preservation of the warmth of the animals during the cold months of winter. Because the down is a non-conductor of heat, and black the warmest colour. It is therefore best adapted to keep in their bodily warmth during the cold of winter. Because his hands serve all the purposes of gathering food, and conveying it to the mouth. Man's mouth is simply an opening; in other animals it is a projection. Because as they have not hands to seize and controul their food, the projecting teeth enable them to snap and hold the objects which they pursue for food. Because the animal pierces the ground with its long snout, and then the small under jaw works freely in the furrow that has been opened, in quest of food. Because, having no teeth, the beak enables them to seize, hold, and divide their food. Because the greater number of birds live by picking up small "As the fishes that are taken in an evil net, and as the birds that are caught in the snare; so are the sons of men snared in an evil time, when it falleth suddenly upon them."—Ecclesiastes ix. Because they live upon worms which they find in the soft mud of streams and marshy places; their long bills, therefore, enable them to dig down into the mud after their prey. Because, as they dig for their prey in the soft sand and mud, they cannot see the worms upon which they live. Nerves are, therefore, distributed to the very point of their bills (where, in other birds, nerves are entirely absent) to enable them to prehend their food. Because they not only feed by dabbling in soft and muddy soil, but they consume a considerable quantity of green food, and their square bills enable them to crop off the blades of grass. "Let the heaven and earth praise him, the seas, and everything that moveth therein."—Psalm lxix. Because the bird lives by suction, dipping its broad bill in search of aquatic worms, mollusks, insects and the roots of weeds. The bill forms a natural spoon, and the muscular points enable the bird to filter the mud, and to retain the nourishment which it finds. Because it wades in marshy places to find its food. Its legs are therefore long, for the purpose of keeping its body out of the water, and above the smaller aquatic plants, while it searches for its prey. Because they live upon nuts, the stones of fruit, and hard seeds. The shape of the bill, therefore, enables them to hold the nut or seed firmly, and the sharp point enables them to split or remove the husks. Because by that means it is enabled to bring the nut or seed nearer the fulcrum, or joint of the jaw. It, therefore, acquires greater power, just as with a pair of nut-crackers we obtain increased power by setting the nut near to the joint. Animals that graze, or feed from the ground, generally have a more powerful muscular formation of the throat than those which feed in other positions, because a greater effort is required to force the food upward, than would be needed to convey it down. Because they are thereby rendered lighter, and do not interfere with the flight of the bird as they would do if they were solid. Greater strength is also obtained by the cylindrical form of the bone, and a larger surface afforded for the attachment of powerful muscles. "And my hand hath found, as a nest, the riches of the people; and as one gathereth eggs that are left, have I gathered all the earth; and there was none that moved the whip, or opened the mouth, or peeped."—Isaiah x. Because, to bear their young in any other manner, would encumber the body, and materially interfere with their powers of flight. As soon as an egg becomes large and heavy enough to be cumbersome to the bird, it is removed from the body. A shell, impervious to air, protects the germ of life within, until from two to twenty eggs have accumulated, and then, although laid at different intervals, their incubation commences together, and the young birds are hatched at the same time. |
