For an hour it was impossible to say with any certainty whether the vessel was or was not standing towards Lincoln Island. She was nearer, but in what direction was she sailing? This Pencroft could not determine. However, as the wind was blowing from the northeast, in all probability the vessel was sailing on the starboard tack. Besides, the wind was favorable for bringing her towards the island, and, the sea being calm, she would not be afraid to approach although the shallows were not marked on the chart. Towards four o’clock--an hour after he had been sent for--Ayrton arrived at Granite House. He entered the dining-room saying,-- “At your service, gentlemen.” Cyrus Harding gave him his hand, as was his custom to do, and, leading him to the window,-- “Ayrton,” said he, “we have begged you to come here for an important reason. A ship is in sight of the island.” Ayrton at first paled slightly, and for a moment his eyes became dim; then, leaning out the window, he surveyed the horizon, but could see nothing. “Take this telescope,” said Spilett, “and look carefully, Ayrton, for it is possible that this ship may be the ‘Duncan’ come to these seas for the purpose of taking you home again.” “The ‘Duncan!’” murmured Ayrton. “Already?” This last word escaped Ayrton’s lips as if involuntarily, and his head drooped upon his hands. Did not twelve years’ solitude on a desert island appear to him a sufficient expiation? Did not the penitent yet feel himself pardoned, either in his own eyes or in the eyes of others? “No,” said he, “no! it cannot be the ‘Duncan’!” “Look, Ayrton,” then said the engineer, “for it is necessary that we should know beforehand what to expect.” Ayrton took the glass and pointed it in the direction indicated. During some minutes he examined the horizon without moving, without uttering a word. Then,-- “It is indeed a vessel,” said he, “but I do not think she is the ‘Duncan.’” “Why do you not think so?” asked Gideon Spilett. “Because the ‘Duncan’ is a steam-yacht, and I cannot perceive any trace of smoke either above or near that vessel.” “Perhaps she is simply sailing,” observed Pencroft. “The wind is favorable for the direction which she appears to be taking, and she may be anxious to economize her coal, being so far from land.” “It is possible that you may be right, Mr. Pencroft,” answered Ayrton, “and that the vessel has extinguished her fires. We must wait until she is nearer, and then we shall soon know what to expect.”
