"A nice dry cave would come in handy if the rain comes," the youth observed. "I know how Gerdak's warriors hated being caught in a storm. They say the jungle is never more dangerous, with winds blowing branches through the air with the speed of flying spears, great trees being uprooted to crash down and crush the unlucky, while Rora, the lightning, flickers angrily about their heads."

"It is a part of jungle living," Tharn said philosophically. "This one will not come for half a sun yet—if it comes at all. Or it may be only a little storm."

"And if it is a bad one?" Trakor asked.

"Then we find a very big tree that is not too old and stand under it until it passes."

"But sometimes storms last for many suns!"

"Not at this season. The rain may fall for suns on end but then the wind is not too strong and there is no danger in moving about."

This was the sixth day since he and Trakor had set out in sustained pursuit of those Ammadians who were holding Dylara. They traveled mostly during the morning and afternoon hours, laying up during the heat of day. To Trakor every hour brought new confidence, increasing dexterity in tree-top travel and his store of jungle lore, under the expert tutelage of Tharn, increased by leaps and bounds. He could stalk Neela, the zebra, or Bana, the deer, across wide stretches of grasslands and, more often than not, get close enough to this wariest of all prey to bring one down with a single spear cast. Tharn had spent all of one sun making him a bow, and with it and a handful of arrows from Tharn's own quiver the boy had learned to handle the weapon with some degree of success. No member of the cat family had faced him and his new-found abilities thus far, but the time must eventually come and he looked forward to it with ill-concealed impatience.

But it was in the trees where Trakor excelled. Already he could keep pace with Tharn for short periods, although he was far from being able to match his friend's over-all agility and stamina. Only when it came to racing swiftly through the trees in the blackness of night was he hopelessly outclassed; for here success depended on an uncanny kind of sixth sense that Tharn had managed to develop only by constant practice and use since almost the day he was able to walk.

Nor was Trakor capable of such quick thinking as that displayed by his hero. A sudden development would freeze Trakor momentarily, while Tharn, because of both environment and heredity possessed reflexes that would have put Rora, the lightning, to shame, would already have the situation in hand.

And as the days passed the bond between the two of them increased in strength and permanence. To Trakor, Tharn was even more a god than on that day he had dropped from the skies to save the youth from the fangs of Sadu. He sought to emulate everything about him—his expression, his walk, his way of speaking—even his way of thinking. Almost every word the mighty Cro-Magnard uttered was stored deep within the mind of his worshiping companion, to be secretly mulled over and absorbed. As for Tharn, he admired the boy's boundless enthusiasm, his unflagging desire to master the lore of the jungle, his uncomplaining acceptance of hardship and his quiet courage.
