It was no use going on, I thought; they must be hiding in the bathing machines after all. And I was actually turning round when something gray on the beach attracted my attention, and I picked it up. To my horror, it was one of Dot's woolen mittens that mother had knitted for him, and which he had worn that very afternoon. I was on their track, after all. I was sure of it now; but when I lifted my eyes and saw the dreary expanse of shore before me, a blank feeling of terror took possession of me. They were not in sight! Nothing but cloudy skies and low chalky cliffs, and the surge breaking on the shingles. All at once a thought that was almost an inspiration flashed across me--the smugglers' cave! Flurry was always talking about it; it had taken a strong hold of her imagination, and both she and Dot had been wild to explore it, only Miss Ruth had never encouraged the idea. She thought caves were damp, dreary places, and not fit for delicate children. Flurry must have tempted Dot to accompany her on this exploring expedition. I was as convinced of the fact as though I had overheard the children's conversation. She would coax and cajole him until his conscience was undermined. How could he have dragged himself so far on his crutches? for the cave was nearly half a mile away from where I stood, and the wind was rising fearfully. And now an icy chill of terror came over me from head to foot--the tide was advancing! It had already covered the narrow strip of sand; in less than an hour it would reach the cliffs, for the shore curved a little beyond the cottage, and with the exception of the beach before the Brambles, the sea covered the whole of the shingles. I shall never, to my dying day, forget that moment's agony when my mind first grasped the truth of the deadly peril those thoughtless babes had incurred. Without instant help, those little children must be drowned, for the water flowed into the cave. Even now it might be too late. All these thoughts whirled through my brain in an instant. Only for a moment I paused and cast one despairing glance round me. The cottage was out of sight. Nurse Gill, and Dorcas, and Betty were scouring the town; no time to run back for help, no hope of making one's voice heard with the wind whistling round me. "Oh, my God! help me to save these children!" I cried, with a sob that almost choked me. And then I dashed like a mad thing toward the shore. 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.
