O, how that mother’s straining eyes followed the struggling youth! How her heart sunk when he went under, and with what joy she saw him emerge again from the waters, and, flinging the waves aside with his strong arms, struggle on in pursuit of her boy!
But it seemed as if his generous efforts were not to succeed; for, though the current was bearing off the boy before his eyes, scarcely ten feet distant, he could not overtake the drowning child.
Twice the boy went out of sight; and a suppressed shriek escaped the mother’s lips; but twice he reappeared, and then, with hands wrung wildly together, and breathless anxiety, she followed his progress, as his form was hurried onward.
