succeed.

He was aroused from his musing by the sound of voices. Looking quickly
down toward the brook, he saw three people walking along the bank. He
recognised them at once as Lois, Dick and Sammie. At first he was
tempted to withdraw farther back among the trees lest he should be
seen. He abandoned this idea, however, feeling quite certain that he
would not be noticed where he was. Lois and Sammie were walking
together, while Dick was a short distance ahead. What they were saying
he could not make out, neither did he care. He had eyes only for the
young woman, and he noted how beautiful she appeared as she walked with
such an upright graceful swing. Was she happy in Sammie's company? he
wondered. She was laughing now, and seemed to be greatly amused at
something her companion was saying. Jasper noted all this, and then
called himself a fool for imagining that she could ever think of him.
No doubt she had already given her heart to the young man by her side,
so he might as well banish her from his mind at once. He would go away
and never see her again.

Acting upon this impulse, he was about to move softly among the trees
and disappear. He had placed his book in his pocket and had reached
for his fish when a cry of terror fell upon his ears. In an instant he

Below, the water swirled and dashed over jagged boulders, receiving its
impetus from the falls farther up stream. The path led along the top,
and in some unaccountable manner Lois had slipped and fallen over the
edge, and had gone swiftly down toward the rushing current below. She
grasped frantically at everything on which she could lay her hands, and
was only able to arrest her downward descent when a few feet from the
water. And there she clung with the desperation of despair, while her
two companions stood above half-paralysed with fear, and unable to
assist her.

When Jasper saw Lois go down to what seemed certain destruction, he
sprang forward and leaped down the bank as if shot from a catapult.
Into the brook he recklessly dashed and like a giant forced his way
across the current and around hidden boulders. At times it seemed as
if he could not keep his feet and that he must be swept away. But that
picture of the clinging woman n
