He gave his questioner lengthy and bewildering directions which not only left the Devon man completely tied up in knots, but with also a reply to a misunderstood question, for the old man had come to the conclusion that Mr. Greenwood was asking the way to Ponhaugh, a small fishing-village about four miles from Auldhaig by the cliff-path.

Gaining the outskirts of the town, Mr. Greenwood commenced the long climb to the edge of the rugged granite cliffs. From the moment he struck the open country he did not see another person of whom he might make further inquiries, but with complete reliance upon the old fisherman's directions he walked briskly along the narrow, winding path.

This he followed for nearly two miles without finding any signs of his quest. Instead, he made the disconcerting discovery that the track split into two parts, one branch trending inland, the other descending steeply to the beach.

Mr. Greenwood took the latter route. Upon gaining the shore he found that the track ended at the firm sands that fronted the base of the rugged and indented line of cliffs.

Undaunted, he proceeded, expecting as he rounded each projection to find the non-existent harbour in which he supposed H.M.S. "Pompey" to be lying; but headland after headland was passed without any satisfactory result.

Presently he arrived at a little bay. The distance between the two enclosing promontories was less than a hundred yards apart. The shore was of sand, but, unlike the rest of the beach, was interrupted by a series of low ledges of rock. Between the water's edge and the base of the cliffs the distance averaged twenty yards, although the waves were almost washing the wall of granite at either end of the bay.

Suddenly Mr. Greenwood caught sight of a cylindrical object lying on the shore. It was a little larger than a football and glistened in the dull light. At every undulation it was flung upon the sand, whence it receded in the undertow until thrown back by the succeeding wave. Attached to it was a short length of frayed rope.

"That must be a mine," decided the alarmed man. "The authorities must be informed."

Although half inclined to retrace his steps, he walked cautiously past it, keeping as close to the cliffs as possible, until he gained the furthermost headland. Here, to his dismay, he found the distant aspect was a misleading one, for his progress was barred by a deep gulley through which the tide was surging right up to the wall of granite.

"I hope the tide is going down," thought Mr. Greenwood.
