"I do not know if the story is true or not. It is possible, but I've met nobody who has ever seen a _wuru_. And if it comes out only at night, where does it hide during the daytime? There is no hole in the ground large enough to conceal it." "Very good," said Green, smiling. Happily, Grizquetr smiled back. He worshiped his foster-father and nursed every bit of affection or compliment he got from him. "Keep that open mind," said Green. "Neither believe nor disbelieve until you have solid evidence one way or another. And keep on remembering that new evidence may come up that will disprove the old and firmly established." He smiled wryly. "I could use some of my own advice. I, for instance, had at one time absolutely refused to put any credence in what I have just seen with my own eyes. I put the story down as merely another idle story of those who sail the grassy seas. But I'm beginning to wonder if perhaps there couldn't be an animal of some kind like the _wuru_." Both were silent for a while as they watched the animals race off like living orange rivers. Overhead, the birds wheeled in their hundreds of thousands of numbers. They, too, were beautiful, and even more colorful than the _hoobers_. Occasionally one lit in the rigging in a burst of dazzling feathers and a fury of melodious song or raucous screeches. "Look!" said the boy, eagerly pointing. "A grass cat! He's been hiding, waiting to catch a _hoober_, and now he's afraid he'll be trampled to death by them." Green's gaze followed the other's finger. He saw the long-legged, tiger-striped body loping desperately ahead of the thundering hoofs. It was completely closed in a pocket of the orange-maned beasts. Even as Green saw him, the sides of the pocket collapsed and the big cat disappeared from sight. If he remained alive he would do so through a miracle. Suddenly, Grizquetr cried, "Gods!" "What's the matter?" cried Green. "On the horizon! A sail! It's shaped like a Ving sail!" Others saw it too. The ship rang with shouts. A trumpeter blew battle stations; Miran's voice rose above those of others as he bellowed through a megaphone; chaos dissolved into order and purpose as everybody went to his appointed place. The animals, children and pregnant women were marshaled into the hold. The gun crews began unloading barrels of powder with a crane from a hatch. Musketmen swarmed up the rigging. The entire topmast crew tumbled aloft and took their places. As Green was already in his, he had some leisure to observe the whole outlay of preparations for fight. He watched Amra hurriedly give her children a kiss, make sure they'd all gone below, then begin tearing strips of cloth for bandages and of wadding for the muskets. Once she looked up and waved at him before turning back to her task. He waved back and got a severe reprimand from the top-captain for breaking discipline. "An extra watch for you, Green, after this is over!"
