Nuwell subsided, but she could see from the expression on his face that he was in a blue funk. This puzzled her. She could not understand why anyone would be afraid of Martians. They were huge, and ugly, and alien, but they were not inimical to humans.

When the Martians came near enough, Maya waved her arms at them and started off to meet them, Nuwell following her at a little distance. The Martians changed course slightly and came toward them.

Maya called childhood memories to her aid. She turned her helmet speaker to its maximum volume, and spoke to them in their own language, in the deepest tones possible to her.

"Children of the past, we seek that place in the desert which is called 'Ultra Vires' by humans," she said. "Can you show us the direction in which we must travel?"

The Martians gathered around her, towering over her. There were four of them. Their huge chests moved slowly, mixing oxygen from their great humps with the surrounding air. Their thin arms hung limp at their sides, and their big ears were pricked forward toward her. Their huge, dark eyes seemed to look through her and beyond her.

"The sun moves toward this place, but there are no humans there now," boomed one of the Martians. "Nothing lives there now except small animals in the walls and corridors."

"This we know," answered Maya. "We wish to go there that we may communicate with other humans and have them come and get us."

She wanted to say that the supplies of oxygen in their marsuit tanks were inadequate to take them anywhere other than Ultra Vires, but she did not know how to say this properly in the Martian language.

But, to her astonishment, the Martian answered as though she had said it.

"If the breathing chemicals which you carry are at such a depleted stage, you cannot chance going astray," said the creature. "Rather than tell you the direction of this place, we shall accompany you there."
