The little island of Herm possessed only one building of importance, a monastery of French refugees. In the great walled-in courtyard, there was present an object of special and curious interest to the monks. The arrival of the _Bladud_ had been observed with astonishment by all the inmates of the monastery, who naturally associated its coming with that of a certain mysterious visitor--a sun-scorched, iron-grey emaciated man--who had recently landed on the island, coming, it was said, from the coast of France. The visitor, who remained in complete seclusion in the building, sedulously nursed back to health and strength, was treated with extraordinary deference and respect by the Superior. That much the monks could not fail to know; but any sly inquiries and surmises on their part were met with the sternest and most peremptory discouragement. Excitement was quickened, therefore, when, only a few hours after the arrival of the air-ship, preparations were made for the distinguished visitor's departure. Linton stood in the courtyard, glancing anxiously at his watch, while Wilton, the engineer, put some finishing touches to the gear. The little man had proved himself a model of discretion. He asked no questions, but now and then threw quick glances towards the tall, thin stranger, who, at a respectful sign from Linton, had taken his seat in the stern of the boat. Whether Wilton knew or suspected the identity of Wilson Renshaw, who now calmly waited for the voyage to commence, Linton could not tell. He suspected that he did, and, little guessing what a few hours would bring forth, he registered a mental promise that the silent, faithful little engineer should not go unrewarded. It struck him that there was a good deal of nervousness in Wilton's manner, as he threw upward glances at the sky. While the preparations were being completed, the Superior of the Order stood close at hand, addressing in subdued tones his deferential and earnest farewells to Mr. Renshaw, and Herrick, raising his eyes, saw the peering faces of at least a score of monks at the upper windows of the monastery. Glancing higher still, he noted with some uneasiness that the scurrying clouds, copper-tinged from the setting sun, betokened the coming of a wild and stormy night. Fervently he breathed a prayer that the aerial voyage might have a happy issue. But by this time he knew enough of air-ships to be aware that there were perils which no scientific inventions, and no precautions, can wholly nullify: risks from defects and mishaps with machinery, dangers from both combined, that at any moment might bring about some irreparable catastrophe. Yet, to-night, everything must be hazarded. Not an hour, not a moment must be lost. The time had come. To let it pass unseized would be to miss the tide at the flood, to sacrifice the touchstone of fortune. He glanced at Wilton: "Ready?"
