The inevitable discovery was made one morning quite early by Gilbert. The beauty of the morning had tempted him, and he had come out to taste the pure air, and to feel the warmth of the coming day. He found that Pringle, as usual, had been early astir; but he took no notice of that. Pringle was ever an early riser, and there was much to be done each day before the little company gathered round the fire for breakfast.
Gilbert strode away down the hill until he came to the eastern shore of the island; waited there a moment, as though undecided in which direction to turn. Then suddenly he became aware of a figure marching steadily towards the rocks at the north of the island; and, gazing more intently, discovered that figure to be Pringle, moving steadily and as though with a set purpose.
"What's the fellow up to now?" Gilbert asked himself, inwardly amused.
He decided to follow; and, keeping a safe distance between his servant and himself, presently saw that servant come to the great line of rocks which bounded the island to the north. But strangely enough Pringle did not stop there; in the mist of the morning he stepped as it seemed straight out into the sea, and disappeared.
Greatly amazed, Gilbert broke into a run, and did not stop until he had come to the very edge of the rocks where, as he had seen them before, they jutted into the sea. But now there was a clean, clear stretch of sand round the base of them, and it was along this stretch of sand that Pringle had gone. Without a moment's hesitation Gilbert Byfield ran round the high wall of rock—and so stepped at once into the heart of the mystery.
Pringle was hurrying ahead of him—not into a watery grave, but straight along a little spit of land that had been left dry by the receding tide. As in a dream, Byfield followed; and presently found himself climbing a path on to another land, and seeing before him as he went evidences of civilization, in the shape of cultivated fields, and decent stone walls and gates. And still Pringle went ahead, looking neither to right nor left nor backwards.
It was only when Gilbert had topped the rise, and had come to a little old-fashioned bridge, that he stopped and let Pringle go ahead, and looked about him. Below lay a prosperous-looking little village, with already early morning smoke rising from many chimneys; about him in all directions were cultivated fields. He seated himself on the parapet of the bridge, and watched the hurrying figure of Pringle dipping down into civilization; and then all in a moment he understood for the first time the fraud that had been practised upon him. To his credit be it said he sat upon the bridge, looking after Pringle (now a mere dot upon the landscape), and shouted with laughter.
He sat there for a long time, until presently the black dot appeared again out of the intricacies of the village, and began to climb the hill. When presently Pringle reappeared, he bore upon his shoulders yet another of those mysterious packages with which he had so thoughtfully provided the islanders. Toiling up the hill, singing cheerfully to himself, he stopped only when the long shadow of Gilbert fell across his path; paused for a moment to look at this surprising stranger watching him; and dropped his burden in the dust of the road.
"Morning, sir," said Pringle, a little nervously. And then, looking at the packing-case that lay between them, he added more nervously still, and yet with a dawning smile about his lips—"Washed ashore, sir!"
