By early summer Gray Wolf could travel with Kazan, if he did not move too swiftly.

She ran at his flank, with her shoulder or muzzle touching him, and Kazan learned not to leap, but to trot.

Very quickly he found that he must choose the easiest trails for Gray Wolf's feet.

Then Kazan would take the leap, and she understood the distance she had to cover.
