But there was no time for dallying with thoughts of such engendering, for he knew that every moment only robbed him of so much power, and he prepared for another effort.

“Hold me tightly,” he said. “Don’t be afraid; only let me have both hands at liberty, so that I may be able to drag myself out.”

She did as he wished, and he struggled hard; but the weight clinging to him frustrated every effort, and after five minutes’ vain expenditure of strength, Brace had great difficulty in finding firm hold for his grasp; while his heart sank, as he found that what at first had seemed but a trifling mishap, and an opportunity for displaying his knight-errantry, now began to loom forth in proportions ominous to them both.

He looked in every direction now, where the tall reeds did not shut out the view, for he was beginning to mistrust his own power; but there was not a soul within sight. And now, for the first time, he raised his voice, to cry loudly for help—despairingly, though, for he could not think it possible that aid could be near. He called again and again; but his voice seemed to be lost in the vast space, and sounded faint, adding to the chill of despair creeping to his heart; till, rousing himself, after regaining his breath, he adopted the plan that he should have tried at first.

“Miss Gernon!—Isa! For Heaven’s sake, speak!” he cried, earnestly, as he gazed at the half-closed eyes and the drooping head. “Try and rouse yourself for one more effort!”

She heard his words, and her eyes unclosed, and rested upon his for an instant.

“That’s right!” he cried, joyfully. “Now, quick! loose your hold of me! Don’t cling, but take hold here of these reeds where my hand is, and hold there tightly for a few moments. I can, then, perhaps, get out, and draw you after me: I am quite powerless here. Can you hold on for half a minute?”

Isa’s pale lips parted, but no audible words came. She obeyed him, though, and he guided her cold, white hand to the sharp-edged leaves.

“Now, then, be brave! Keep a good heart, for the sake of all who love you!” he whispered; and loosing his hold, he paused for an instant or two, to find that she was striving gallantly to obey him. “Only a few moments!” he cried; and then, summoning all his strength, he left her, and by means of a desperate effort fought and plunged his way through the now clinging—now yielding mass, till—how he could not tell—he forced his way on, to lie panting, at full length, amongst the rushes. The next moment a cry of despair burst from his breast; for, as he drew himself along to where Isa Gernon clung, he saw that the tuft of reeds, disturbed by his frantic efforts, were parting from the edge, and directly after the poor girl’s head sank again beneath the black water.

A rush—a plunge—a fierce struggle, and Brace was nearly free of the mosses and water-weeds; but now they seemed to cling round him more than ever, hampering his efforts, and minutes seemed to have elapsed before he had shaken himself clear, and dived down into the depths of the pool, forcing his way lower and lower till half strangled, when, rising to the surface, he drew a long, gasping breath, and then again plunged down.
