And a chief pleasure, in those early days of its irresponsible youth, was to lie low, like Brer Fox, just before the little turbulent tributaries came to join it from the Alps, and to refuse to acknowledge them when in, but to run for miles side by side, the dividing line well marked, the very levels different, the Danube utterly declining to recognize the new-comer.  Below Passau, however, it gave up this particular trick, for there the Inn comes in with a thundering power impossible to ignore, and so pushes and incommodes the parent river that there is hardly room for them in the long twisting gorge that follows, and the Danube is shoved this way and that against the cliffs, and forced to hurry itself with great waves and much dashing to and fro in order to get through in time.  And during the fight our canoe slipped down from its shoulder to its breast, and had the time of its life among the struggling waves.  But the Inn taught the old river a lesson, and after Passau it no longer pretended to ignore new arrivals.

This was many days back, of course, and since then we had come to know other aspects of the great creature, and across the Bavarian wheat plain of Straubing she wandered so slowly under the blazing June sun that we could well imagine only the surface inches were water, while below there moved, concealed as by a silken mantle, a whole army of Undines, passing silently and unseen down to the sea, and very leisurely too, lest they be discovered.

Much, too, we forgave her because of her friendliness to the birds and animals that haunted the shores.  Cormorants lined the banks in lonely places in rows like short black palings; gray crows crowded the shingle-beds; storks stood fishing in the vistas of shallower water that opened up between the islands, and hawks, swans, and marsh birds of all sorts filled the air with glinting wings and singing, petulant cries.  It was impossible to feel annoyed with the river’s vagaries after seeing a deer leap with a splash into the water at sunrise and swim past the bows of the canoe; and often we saw fawns peering at us from the underbrush, or looked straight into the brown eyes of a stag as we charged full tilt round a corner and entered another reach of the river.  Foxes, too, everywhere haunted the banks, tripping daintily among the driftwood and disappearing so suddenly that it was impossible to see how they managed it.

But now, after leaving Pressburg, everything changed a little, and the Danube became more serious.  It ceased trifling.  It was halfway to the Black Sea, within scenting distance almost of other, stranger countries where no tricks would be permitted or understood.  It became suddenly grown-up, and claimed our respect and even our awe.  It broke out into three arms, for one thing, that only met again a hundred kilometers farther down, and for a canoe there were no indications which one was intended to be followed.

“If you take a side channel,” said the Hungarian officer we met in the Pressburg shop while buying provisions, “you may find yourselves, when the flood subsides, forty miles from anywhere, high and dry, and you may easily starve.  There are no people, no farms, no fishermen.  I warn you not to continue.  The river, too, is still rising, and this wind will increase.”
