do you understand why what I say is important?”
“I’m sorry, Per Hiero. I’ll let you be the guide. Only,” she burst out, “please hurry, that’s all. Somehow, I feel it’s very important! Why,” she added, “don’t the Unclean control everybody’s mind, if so many are unshielded?”
He laughed. “I’m sure it is important, at least to you. Now let’s review what I just taught you. But first, the Unclean can’t control an unconscious mind, one that isn’t sending at all, unless they have the person in their physical power or in close contact. Now, to begin, the shield is to be conceived by your mind as an arc, surmounted by the Cross. Visualize this and then practice, with your eyes open, making it appear in your physical vision, so that the picture blocks out the horizon. Next—” He droned on, using his superb memory simply to repeat what old Per Hadena used to use as the basis for his lectures. This allowed Hiero to think of other things and to keep watch. He kept an eye out for the enemy flier, but no trace of it appeared. Many hawks were in the sky, though, and he saw them diving on the countless water birds. Once they came to a place where a small herd of the great water pigs lay floating near the shore. At the sight of the travelers, the big, shiny-creatures submerged in a welter of foam and vanished.
At another time they had to cross the marsh, previously-glimpsed, where a long, skinny finger of the Palood thrust south and caused an oozing stream to drain into the Inland Sea. Hiero had Klootz and the bear gallop across the dirty shallows at the juncture of marsh and sea, while he watched the giant reeds carefully. Nothing appeared, however, and the whole area was only a quarter of a mile wide. Once through it, the pleasant sandy shore began again.
They camped that night under a rock overhang, and Hiero allowed a tiny fire, first bringing a rock over to screen it even from the water, which the girl thought amusing.
“There are ships out there, you know,” he reminded her. “Probably very few contain anyone or anything friendly. You ought to remember; you were on one. And a fire might draw other unpleasant things too, not human at all.” Having silenced her, he relented, and after supper (the last snapper egg), he allowed the lessons to continue.
“I want you to realize something,” he said next. “I could speed those lessons up considerably. The way to do it, and it’s sometimes done in an emergency, is to go into your mind and do the teaching there. But I’m not going to.”
