Harriet lay on the rocks, at a point where she could not see the water, and there Jane joined her.
"What I want you to do," Harriet explained in whispers, at the same time on the alert for sound or sign of the boys, "is to stay here, or not far from here, so that you can warn the girls in case I signal by making a cawing noise like a crow.

I don't want the girls to make too much noise, for it would spoil our fun if the boys should discover our hiding place." "But how am I going to get back if I have to do so in a hurry ?" "Can you go down a rope ?" "Show me the rope that I can't go down," boasted Jane.
"How about this one ?" smiled Harriet, producing a coil of quarter inch manila rope.
"Well, it's small, but I'll try it.

Where do you wish me to climb ?" "I'll show you.

Take hold of my feet and don't you dare let go.

I surely shall break my neck if you do." Harriet crawled over the edge, Jane grasping her by the ankles to prevent her from falling.
