They rode off at an easy pace, the dolphins rising above the tops of the tallest vegetation. Gerry found that it was easy to sit the saddle as long as he bent a little forward to overcome the resistance of the water against his chest. They were about thirty or forty feet down. On Earth such a depth would have been uncomfortable, but the lighter gravity of Venus made it easily bearable.
Gerry glanced back. Closana was riding a few feet behind him, slender and erect, controlling her restless dolphin as easily as though she had been accustomed to such steeds all her life. Angus was grinning broadly through his globular glass helmet as he sat astride a particularly big dolphin and swung his light bladed water-sword from side to side.
"If any of our friends back on Earth could see us now in some sort of an astral spectroscope," the big Scot cried, "they'd think themselves crazy. Maybe this is only a nightmare at that! Do you think we'll wake up soon and find ourselves safe back on board the Viking?"
"I'm afraid not," Gerry answered. He wondered in what part of this vast sea the twisted hulk of the Viking was now lying.
All day they rode, roughly following the shoreline to the northward. Whenever it got so deep that nothing was visible below but a vast green shadow Gerry headed inland until the tops of the sea gardens again came into view. Sarnak had told them that by the middle of the next day it should be safe for them to come above water and check their maps and put fresh chemical cartridges in the cylinders of their helmets. The Scaly Ones patrolled their coast line in shallow open boats, but they did not go beyond their own borders.
Once Gerry checked his dolphin and then headed downward as he caught sight of something big and dark lying on the sand. The others followed him. It was the broken and rusting hulk of a space-ship, a vessel of a strange type with a name in an unknown tongue still visible on the shattered stern. The wreck must have been there for a very long time, for the sand was heaped high about it and sea-weeds grew up through the open hatches.
"Leaping ray-blasts!" McTavish said softly. "Yon craft never came from either Earth or Mars."
"Probably from some far distant planet in outer space that we've never heard of," Gerry said. "Some adventurous wanderer of the interstellar regions who came to grief in this lonely spot."
It was desolate and forlorn, the sight of that wrecked vessel from so long ago. It made Gerry think of his own lost command. There were clean picked white bones of strange shape lying about on the sand. Gerry saluted, a tribute to those strange and forgotten wanderers of space, and then urged his dolphin to a higher level again.
