My despair gave me courage, but my progress was difficult and slow. It was impossible to keep up that pace over the heavy shingles with the wind tearing round me and taking away my breath.

Several times I had to stand and collect my energies, and each time I paused I called the children's names loudly. But, alas! the wind and the sea swallowed up the sound.

How fast the tide seemed coming up! The booming of the breakers sounded close behind me. I dared not look—I dared not think. I fought and buffeted the wind, and folded my cloak round me.

"Out of the depth I have cried unto Thee." Those were the words I said over and over to myself.

I had reached the cave at last, and leaned gasping and nearly faint with terror before I began searching in its dim recesses.

Great masses of slimy seaweed lay heaped up at the entrance; a faint damp odor pervaded it. The sudden roar of wind and sea echoed in dull hollowness, but here at least my voice could be heard.

"Flurry-Dot!" I screamed. I could hear my own wild shriek dying away through the cave. To my delight, two little voices answered:

"Here we are Esther! Come along, we are having such a game! Flurry is the smuggler, and I am the Preventive man, and Flossy is my dog, and—oh, dear! what is the matter?" And Dot, who had hobbled out of a snug, dry little corner near the entrance, looked up with frightened eyes as I caught him and Flurry in my arms. I suppose my face betrayed my fears, for I could not at that moment gasp out another word.
