They set forth at once, the landlord accompanying them. It was not thought necessary to send word to Captain Corbet, as he would not be able to do anything, and might only embarrass their movements by an untimely fussiness, or by an anxious determination to accompany them in Roach’s boat. A walk of a few minutes brought them to the back bay, where the boat was lying. It was soon afloat, and the party embarked. Then the sail was hoisted, and as the wind was fair and fresh, they moved rapidly through the water, heading for Oak Island. On the way the landlord informed them that he had told to Bart and Pat the story of Oak Island, and gave them a kind of summary of the same story. From this the boys were able to understand why it was that their absent companions had not accompanied them, though they were still at a loss to know why it was that they had made such a secret of their plan, and what their purpose had been in thus setting out by themselves. They could only conclude that Bart and Pat wished to have the whole glory of making some discovery by themselves, with which they should astonish their companions; and if there was any hope left in their minds, it was that they had purposely secreted themselves from Roach, so as not to be disturbed in their investigations. And this hope, though it was a faint one, served to sustain them to some extent. In a short time they reached Oak Island, where they landed at the very place which had been chosen by Bart and Pat for their landing. Here the first thing that they noticed was the boat which their friends had brought, and which lay as they had left it. It was with melancholy forebodings that they looked upon it, wondering what had been the fate of those who had brought it here. But there was no time to waste in useless regrets or idle fears. There was a very serious business before them--the search after their lost companions. They went up from the beach upon the island just as Pat and Bart had gone, and noticed the same things. They came to the mound of bluish clay, and saw the pit close by filled with water. They examined this narrowly, as though they feared to find their friends here. Then they went on further. Another mound, marking the presence of another pit. They now began to understand the full meaning of these “pits” to which Roach had alluded. It was with a feeling of great relief that they saw no signs here of their lost friends. From this they went on farther to a third pit. “I can’t imagine,” said the landlord, “how any harm could have happened. Two sensible boys like these couldn’t have fallen into any trouble here. They wouldn’t feel inclined to jump into a flooded pit and drown themselves. As to this pit, it is dry; and I don’t think they would go down into it. Why should they? They wouldn’t jump down, for they were not yet quite tired of life, and there’s nothing here to show that they lowered themselves down.” Each solemnly shook his head.
