His one chance was to attract the anglers attention.

Had that angler been any one but Rollitt, it might have been easy.
Arming himself with a handful of stones, Fisher minor waited till the boat came within a few yards.

Then with a great shout he flung with all his might at the boat.
The sudden fusillade might have been unheeded, had not one stone struck the angler's hand just as he was manoeuvring his landing-net under the fish.

In the sudden start he missed his aim and looked up.
"Look out!" screamed Fisher.

"You're adrift! Catch the branch!" And he pointed wildly to the branch of an ash which straggled out over the water just above the fall.
Rollitt took in the situation at last.
