“Big idea! Make it wide at the open end so’s she can git the call better. If you make it narrow the sound won’t go out so clear, you see.”

At the finger of land, Jinks stood out on a large rock and shouted and shouted at Prunel who was crying fearfully and kneeling in the bottom of the boat while clinging to the oar-lock.

At the echo of Jinks’ call she looked about but did not at first see the boys standing where the channel curved in towards land. At the second shout, however, she looked in the direction from which the sound came, and stopped wailing as she saw the group of police waiting to assist her.

Then she heard her name called and listened to what was said.

“We’re going to send the dog out to the boat—you call ‘Here Crummie! here Crummie!’ as soon as he goes in the water. He will come to you and then you will find a rope tied to his collar. Fasten the rope to the ring in the boat and we will haul you in!”

It needed several trials before Prunel understood the plan, but once she did it was all right, although the boat was fast reaching the place where the current flowed in towards land so the dog had to hurry out with the rope if it was to work as planned.

“Here I come—get him ready!” called the boy who had been sent for the rope.

The boys turned and saw him racing along with a long coil of swing rope that had been hastily cut down to use. Dink, being the swiftest runner in camp, was soon back with the Police and Jinks.

One end of the rope was tied to Crummie’s old leather collar and then he was sent in to bring out Prunel. At the same time Jinks shouted through the megaphone:

“Call him, Prunel! Call him, again and again, till he reaches you with the rope.”
