Suddenly he heard a sharp report and something struck the water smartly within a few inches of his head, spattering his face with spray.  He heard a second report, and saw one of the sentinels with his rifle at his shoulder, a light cloud of blue smoke rising from the muzzle.  The man in the water saw the eye of the man on the bridge gazing into his own through the sights of the rifle.  He observed that it was a gray eye and remembered having read that gray eyes were keenest, and that all famous markmen had them.  Nevertheless, this one had missed.

A counter-swirl had caught Farquhar and turned him half round; he was again looking into the forest on the bank opposite the fort.  The sound of a clear, high voice in a monotonous singsong now rang out behind him and came across the water with a distinctness that pierced and subdued all other sounds, even the beating of the ripples in his ears.  Although no soldier, he had frequented camps enough to know the dread significance of that deliberate, drawling, aspirated chant; the lieutenant on shore was taking a part in the morning’s work.  How coldly and pitilessly—­with what an even, calm intonation, presaging, and enforcing tranquillity in the men—­with what accurately measured intervals fell those cruel words: 

“Attention, company!...  Shoulder arms!...  Ready!...  Aim!...  Fire!”

Farquhar dived—­dived as deeply as he could.  The water roared in his ears like the voice of Niagara, yet he heard the dulled thunder of the volley and, rising again toward the surface, met shining bits of metal, singularly flattened, oscillating slowly downward.  Some of them touched him on the face and hands, then fell away, continuing their descent.  One lodged between his collar and neck; it was uncomfortably warm and he snatched it out.

As he rose to the surface, gasping for breath, he saw that he had been a long time under water; he was perceptibly farther down stream—­nearer to safety.  The soldiers had almost finished reloading; the metal ramrods flashed all at once in the sunshine as they were drawn from the barrels, turned in the air, and thrust into their sockets.  The two sentinels fired again, independently and ineffectually.

The hunted man saw all this over his shoulder; he was now swimming vigorously with the current.  His brain was as energetic as his arms and legs; he thought with the rapidity of lightning.

“The officer,” he reasoned, “will not make that martinet’s error a second time.  It is as easy to dodge a volley as a single shot.  He has probably already given the command to fire at will.  God help me, I cannot dodge them all!”

An appalling plash within two yards of him was followed by a loud, rushing sound, diminuendo, which seemed to travel back through the air to the fort and died in an explosion which stirred the very river to its deeps!  A rising sheet of water curved over him, fell down upon him, blinded him, strangled him!  The cannon had taken a hand in the game.  As he shook his head free from the commotion of the smitten water he heard the deflected shot humming through the air ahead, and in an instant it was cracking and smashing the branches in the forest beyond.
