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.
