Suddenly he became aware that something was wrong with the raft-and a few hundred yards ahead was a stretch of foaming rapids
that would smash it to kindling wood. The woman stood leaning on the shaft of a broken sweep, watching the man. With unhurried but almost
superhuman strength he was working the other sweep from the rear, aiming for the opposite bank.
The struggle seemed hopeless. Torrance read it at a glance, unaccustomed as he was to water. The tug of the rapids was drawing them
swiftly downward in a course that was too slightly diagonal to its current to promise more than the faintest hope. The man seemed suddenly to
grasp the extent of their peril, for his arms moved more quickly, the bow of the raft swinging about and pointing upstream: but still the current
gripped them relentlessly.
The woman lifted her head and looked down along the whirling eddies to the froth of broken water. For a moment she stood, rigid, then
turned to the horses, and from among them sprang a huge dog. Into its mouth she pressed the end of a rope, and it leaped far into the water.
