He groped in the darkness, found a scull, and took it from Brown's hand; the boat spun, hesitated, plunged again.
All about them was the roar of the rapid.
The starboard side of the boat caught on a rock; Hornblower felt icy water deluge his legs as it poured in over the side behind him.
But already he was thrusting madly and blindly with his scull against the rock, he felt the boat slip and swing, he thrust so that the swing was accentuated, and next moment they were clear, wallowing sluggishly with the water up to the thwarts. Another rock slid hissing past, but the roar of the fall was already dwindling.
"Christ!" said Bush, in a mild tone contrasting oddly with the blasphemy.
"We're through!"
"D'you know if there's a bailer in the boat, Brown?" demanded Hornblower.
"Yessir, there was one at my feet when I came on board."
"Find it and get this water out.
Give me your other scull."
Brown splashed about in the icy water in a manner piteous to hear as he groped for the floating wooden basin.
"Got it, sir," he reported, and they heard the regular sound of the water being scooped overside as he began work.
In the absence of the distraction of the rapids they were conscious of the wind again now, and Hornblower turned the boat's bows into it and pulled slowly at the sculls.
Past experience appeared to have demonstrated conclusively that this was the best way to allow the current a free hand to take the boat downstream and away from pursuit.
Judging by the speed with which the noise of the rapid was left behind the current of this river was very fast indeed — that was only to be expected, too, for all the rain of the past few days must have brought up every river brim full.
Hornblower wondered vaguely again what river this was, here in the heart of France.
The only one with whose name he was acquainted and which it might possibly be was the Rhone, but he felt a suspicion that the Rhone was fifty miles or so farther eastward.
This river presumably had taken its origin in the gaunt Cevennes whose flanks they had turned in the last two days' journey.
In that case it would run northward, and must presumably turn westward to find the sea — it must be the Loire or one of its tributaries.
And the Loire fell into the Bay of Biscay below Nantes, which must be at least four hundred miles away.
Hornblower's imagination dallied with the idea of a river four hundred miles long, and with the prospect of descending it from source to mouth in the depth of winter.
A ghostly sound as if from nowhere brought him back to earth again.
As he tried to identify it it repeated itself more loudly and definitely, and the boat lurched and hesitated.
They were gliding over a bit of rock which providence had submerged to a depth sufficient just to scrape their keel.
Another rock, foam covered, came boiling past them close overside. It passed them from stern to bow, telling him what he had no means of discovering in any other way in the blackness, that in this reach the river must be running westward, for the wind was in the east and he was pulling into it.
"More of those to come yet, sir," said Bush — already they could hear the growing roar of water among rocks.
"Take a scull and watch the port side, Brown," said Hornblower.
"Aye aye, sir. I've got the boat nearly dry," volunteered Brown, feeling for the scull.
The boat was lurching again now, dancing a little in the madness of the river.
Hornblower felt bow and stern lift successively as they dropped over what felt like a downward step in the water; he reeled as he stood, and the water remaining in the bottom of the boat surged and splashed against his ankles.
The din of the rapid in the darkness round them was tremendous; white water was boiling about them on either side.
The boat swung and pitched and rolled.
Then something invisible struck the port side amidships with a splintering crash.
Brown tried unavailingly to shove off, and Hornblower swung round and with his added strength forced the boat clear.
They plunged and rolled again; Hornblower, feeling in the darkness, found the gunwale stove in, but apparently only the two upper strakes were damaged — chance might have driven that rock through below the water line as easily as it had done above it.
Now the keel seemed to have caught; the boat heeled hideously, with Bush and Hornblower falling on their noses, but she freed herself and went on through the roaring water.
The noise was dying down again and they were through another rapid.
"Shall I bail again, sir?" asked Brown.
"Yes.
Give me your scull."
"Light on the starboard bow, sir!" interjected Bush.
Hornblower craned over his shoulder.
Undoubtedly it was a light, with another close beside it, and another farther on, barely visible in the driving snow.
That must be a village on the river bank, or a town — the town of Nevers, six kilometres, according to the coachman, from where they had embarked.
They had come four miles already.
"Silence now!" hissed Hornblower.
"Brown, stop bailing."
With those lights to guide him in the darkness, stable, permanent things in this insane world of infinite indefiniteness, it was marvellous how he felt master of his fate once more.
He knew again which was upstream and which was down — the wind was still blowing downstream.
With a touch of the sculls he turned the boat downstream, wind and current sped her along fast and the lights were gliding by rapidly.
