"In a way—not see, but hear. There is a machine which makes for the captain of the above-seas ship a picture of where the sub lies or moves so that he may follow its course. Then when he is near enough he drops the container and the power breaks free—to also break apart the sub."
"Yet the making of such containers and the imprisoning of the power within them," Torgul said, "this is the result of a knowledge which is greater than any save the Foanna may possess. You do not have it?" His conclusion was half statement, half question.
"No. It took many years and the combined knowledge of many men among my people to make such containers, such a listening device. I do not have it."
"Why then think of what we do not have?" Torgul's return was decisive. "What do we have?"
Ross's head came up. He was listening, not to anything in that cabin, but to a sound which had come through the port just behind his head. There—it had come again! He was on his feet.
"What—?" Vistur's hand hovered over the ax at his belt. Ross saw their gaze centered on him.
"We may have reinforcements now!" The Terran was already on his way to the deck.
He hurried to the rail and whistled, the thin, shrill summons he had practiced for weeks before he had ever begun this fantastic adventure.
A sleek dark body broke water and the dolphin grin was exposed as Tino-rau answered his call. Though Ross's communication powers with the two finned scouts was very far from Karara's, he caught the message in part and swung around to face the Rovers who had crowded after him.
"We have a way now of learning more about your enemies."
