Lorraine was rather keen on entomology, and though she had no net with her, she pulled off her hat and ran in eager pursuit of the butterfly. It was an exciting chase, several times she nearly secured it, but it managed to elude her and flitted tantalizingly away. At last it paused and hovered, then settled on a spray of wild rose. Lorraine crept up stealthily, hat in hand. Surely she had her prize now? But just at the critical moment, again the lovely wings fluttered; she made a grab and a dash forward simultaneously, then suddenly the earth seemed to open and swallow her up.

As a matter of fact, she fell about nine feet, and lodged on a heap of shale. It was so totally unexpected, and so amazing, that she lay there for a moment or two almost stunned. Then she moved cautiously and sat up. She realized what had happened. In her mad rush after the butterfly she had not noticed where she was going, and she had fallen down the shaft of an old tin-mine. Above her were its rocky sides, with bushes and a patch of blue sky at the top. Below the ledge where she sat it sloped away towards a black hole. Lorraine, still a little dazed, shuddered as she looked down in the direction of that dark pit. She was unhurt, and she was safe enough on the edge of the shale, but how was she to get up to the level of the ground above? The sides of the shaft were far too steep to climb, and a slip might mean a plunge down, down, down into that horrible depth that loomed below.

She stood up cautiously and shouted with all the force of her lungs. There was no reply. Again and again she called, but beyond the alarm-note of a blackbird there was no response. She began to grow seriously frightened. She must be some distance from the tower, and she had wandered from the rest of the party. Suppose nobody heard her calling? The bare idea sent her breath in gasps. In time, no doubt, they would notice her absence, but they would not exactly know where to search for her. They might even imagine that she had gone home. Suppose the night came on before she was found? Suppose even days were to pass and nobody remembered the disused mine or thought of looking for her there! With white cheeks and trembling hand she leaned against the side of the shaft and called with what breath she could still muster.

There was a rustling among the heather above, and a face suddenly blocked the blue of the sky—a vacant face that peered down with the curiosity of a child. Lorraine gave a fluttering cry of relief.

"Landry!" she called. "Landry!"

How or from where he appeared she could not guess, though it was possible that he had seen the school passing near Windy Howe and had followed Claudia in the distance. He stared down at Lorraine with a certain amount of interest, but as much unconcern as if she were a bird or a rabbit.

"Landry!" she cried again. "Claudia is up by the tower. Go and tell her I have fallen down the old mine!"

The bushes rustled, and once more that patch of blue sky appeared above. Landry had gone indeed, but would he bring help? Lorraine feared that all he cared about was to find Claudia, and that with his customary taciturnity it was quite within the bounds of possibility that he might never mention her predicament at all.
