It is probable that his sudden weight jolted the plank out of its position. For hardly was he safe on the turf again when he heard a sharp cry. Throwing a look behind, he saw his pursuer totter, clutch at the slipping timber, and, still clutching at it, turn a somersault and disappear.
Tristram ran on. Then a series of shouts rang in his ear, and he looked behind again. The other three men had come up, and were running aimlessly to and fro upon the farther bank. From the pit at their feet rose a gurgling and heartrending appeal for help. It was plain the poor fellow was drowning, and equally plain that his comrades could not swim. Tristram took a couple of strides, and halted. Then he faced about and walked back towards the dyke, his heart still knocking against his ribs.
"Help! help!" resounded from the depths of the dyke.
"Gentlemen," said Tristram, "are you aware that your comrade is perishing?"
They stared at him helplessly. Without more to-do he slipped off his shoes, and sliding down the bank, flung himself forward into the icy water. In two strokes he was able to grasp the drowning man by the collar and began to tug him towards the bank.
But it appeared that the fellow had other views on the right method of being saved: for, casting his arms about Tristram's neck and wreathing them tightly, he not only resisted all efforts to drag him ashore, but began to throttle his rescuer. In the struggle both went under.
As the water closed over them the drowning man relaxed his hold a little, and Tristram, breaking free, rose to the surface coughing and spouting like a whale. Another moment, and a hand appeared above the water, its fingers hooked like a bird's talons. This grisly appeal determined Tristram to make another attempt. He kicked out, seized the uplifted arm just around the wrist, and with half a dozen fierce strokes managed to gain the bank at the feet of his enemies. While he dug a hand into the soft mud and paused for a moment to shift his hold and draw breath, one of the three unclasped a leathern belt and dangled it over the brink. Tristram reached out, caught it by the buckle, and was helped up with his burden. Two pairs of strong arms grasped and pulled him forward.
"Turn him—on his face and let the water—run out; then on his back— give him air!" he gasped, and with that fainted clean away on the green turf.
When his senses came back, the three men were bending over him.
"Where is the other one?" he asked feebly.
