"I don't wonder that some place around here is called the Witch's Head," she remarked. "This must be like the place where Macbeth saw the witches brewing their potions."
"Except that they brewed them 'in lightning, thunder and in rain'," said Drew. "Those are the only things that are missing."
He had scarcely spoken when there was a rumbling that sounded like thunder. Drew was startled, and Ruth grew slightly pale.
"That's funny," remarked Tyke. "Weather's as clear as a bell too. This ain't the hurricane season."
The captain was in a brown study, seemingly unheedful of the rumbling sound. In a moment he roused himself and said:
"Well, now let's scatter about and see if we can find anything that looks like The Three Sisters or the Witch's Head."
Grimshaw sat down to rest, not wishing to put too heavy a strain on the leg that had been injured, and the others wandered about for half an hour trying to discover anything that might be identified as the places named on the map. But their efforts were fruitless, and the captain, looking at his watch, called a halt.
"Nothing more doing now," he said. "We have only time to get back to the boat. But we've got our bearings and have done a good afternoon's work. To-morrow's a new day, and we'll get on the job early."
Reluctantly, the little party went back to the boat. They found the crew waiting for them and were pulled rapidly to the schooner, whose anchor lights were already gleaming like fireflies in the sudden dusk.
