“It is a survival—a survival of the fittest. Mr. Darwin invented the theory that goes by that name, but the Ornithorhynchus was the first to put it to actual experiment and prove that it could be done. Hence it should have as much of the credit as Mr. Darwin. It was never in the Ark; you will find no mention of it there; it nobly stayed out and worked the theory. Of all creatures in the world it was the only one properly equipped for the test. The Ark was thirteen months afloat, and all the globe submerged; no land visible above the flood, no vegetation, no food for a mammal to eat, nor water for a mammal to drink; for all mammal food was destroyed, and when the pure floods from heaven and the salt oceans of the earth mingled their waters and rose above the mountain tops, the result was a drink which no bird or beast of ordinary construction could use and live. But this combination was nuts for the Ornithorhynchus, if I may use a term like that without offense. Its river home had always been salted by the flood-tides of the sea. On the face of the Noachian deluge innumerable forest trees were floating. Upon these the Ornithorhynchus voyaged in peace; voyaged from clime to clime, from hemisphere to hemisphere, in contentment and comfort, in virile interest in the constant change of scene, in humble thankfulness for its privileges, in ever-increasing enthusiasm in the development of the great theory upon whose validity it had staked its life, its fortunes, and its sacred honor, if I may use such expressions without impropriety in connection with an episode of this nature. “It lived the tranquil and luxurious life of a creature of independent means. Of things actually necessary to its existence and its happiness not a detail was wanting. When it wished to walk, it scrambled along the tree-trunk; it mused in the shade of the leaves by day, it slept in their shelter by night; when it wanted the refreshment of a swim, it had it; it ate leaves when it wanted a vegetable diet, it dug under the bark for worms and grubs; when it wanted fish it caught them, when it wanted eggs it laid them. If the grubs gave out in one tree it swam to another; and as for fish, the very opulence of the supply was an embarrassment. And finally, when it was thirsty it smacked its chops in gratitude over a blend that would have slain a crocodile. “When at last, after thirteen months of travel and research in all the Zones it went aground on a mountain-summit, it strode ashore, saying in its heart, 'Let them that come after me invent theories and dream dreams about the Survival of the Fittest if they like, but I am the first that has done it!
