"Yes," she said, "I won't be long," going next after the long, thick horseradish root with the burning hot taste. "I think I know a way to keep him away from our things," Ayla said, pointing at the young canine playfully gnawing on what was left of her leather camp shoe. "I'm going to make 'Wolf repellent.'"

They headed southeast from their camping place to get back to the river they had been following. The windswept dust had settled overnight, and in the stark, clear air the boundless sky revealed the distant reach of the horizon that had been obscured before. As they rode across country their entire view, from one edge of the earth to the other, north to south, east to west, undulating, billowing, constantly in motion, was grass; one vast, encompassing grassland. The few trees that existed near waterways only accentuated the dominant vegetation. But the magnitude of the grassy plains was more extensive than they knew.

Massive sheets of ice, two, three, up to five miles thick, smothered the ends of the earth and sprawled over the northern lands, crushing the stony crust of the continent and depressing the bedrock itself with its inconceivable weight. South of the ice were the steppes – cold, dry grassland as wide as the continent, marching from western ocean to eastern sea. All the land bordering the ice was an immense grassy plain. Everywhere, sweeping across the land, from lowland valley to windblown hill, there was grass. Mountains, rivers, lakes, and seas that provided enough moisture for trees were the only intrusions into the essential grassy character of the northern lands during the Ice Age.

Ayla and Jondalar felt the level ground begin sloping downhill toward the valley of the larger river, though they were still some distance from the water. Before long they found themselves surrounded by tall grass. Stretching to see over the eight-foot growth, even from Whinney's back, Ayla could see little more than Jondalar's head and shoulders between the feathery tops and the nodding stems of minuscule florets, turning gold with a faintly reddish tinge, atop the thin, blue-green stalks. She glimpsed his dark brown mount now and then, but recognized Racer only because she knew he was there. She was glad for the advantage of height the horses gave them. Had they been walking, she realized, it would have been like traveling through a dense forest of tall green grass waving in the wind.

The high grass was no barrier, parting easily in front of them as they rode, but they could see only a short distance past the nearest stalks, and behind them the grass sprang back, leaving little trace of the way they had come. Their view was limited to the area immediately around them, as though they took with them a pocket of their own space as they moved. With only the brilliant incandescence tracing its familiar path through the clear deep blue above, and the bending stalks to show the direction of the prevailing wind, it would have been more difficult to find their way, and very easy to become separated.

As she rode, she heard the soughing wind and the high whine of mosquitoes zinging by her ear. It was hot and close in the middle of the dense growth. Though she could see the tallgrass swaying, she barely felt a breath of wind. The buzz of flies and a whiff of fresh dung told her that Racer had recently dropped scat. Even if he hadn't been just a few paces ahead, she would have known it was the young stallion who had passed that way. His scent was as distinctively familiar to her as that of the horse she was riding – and her own. All around was the rich humus odor of the soil, and the green smell of burgeoning vegetation. She did not classify smells as bad or good; she used her nose as she did her eyes and ears, with knowledgeable discrimination to help her investigate and analyze the perceptible world.

After a time, the sameness of the scenery, of long green stalk after long green stalk, the rhythmic gait of the horse, and the hot sun almost directly above, made Ayla lethargic; awake, but not fully aware. The repetitive tall, thin, jointed grass stems became a blur she no longer saw. Instead, she began to notice all the other vegetation. Much more than grass grew there, and as usual, she took mental note of it, without consciously thinking about it. It was simply the way she saw her environment.

There, Ayla thought, in that open space – some animal must have made that by rolling in it – those are goosefoots, what Nezzie called goosefoots, like the pigweed near the clan's cave. I should pick some, she mused, but made no effort to do so. That plant, with the yellow flowers and leaves wrapped around the stem, that's wild cabbage. That would be good to have tonight, too. She passed it by as well. Those purple-blue flowers, with the small leaves, that's milk vetch, and it has a lot of pods. I wonder if they're ready? Probably not. Up ahead, that wide white flower, sort of rounded, pink in the middle, it's wild carrot. It looks like Racer stepped on some of the leaves. I should get my digging stick, but there's more over there. Seems to be a lot of it. I can wait, and it's so hot. She tried to swat away a pair of flies that buzzed around her sweat-damp hair. I haven't seen Wolf for a while. I wonder where he is?

She turned to look for the wolf and saw him following close behind the mare, sniffing the ground. He stopped, lifting his head to catch another scent, then disappeared into the grass on her left. She saw a large blue dragonfly with spotted wings, disturbed by the wolf's passage through the dense living screen, hovering near the place he had been, as though marking it. A short time later, a squawk and a whir of wings preceded the sudden appearance of a great bustard taking to the air. Ayla reached for her sling, wrapped around her head across her forehead. It was a handy place to keep it to get it quickly, and it kept her hair out of the way besides.

But the huge bustard – at twenty-five pounds the heaviest bird on the steppes – was a speedy flier for its size, and it was out of range before she got a stone out of her pouch. She watched the mottled bird with dark-tipped white wings building up speed, its head stretched forward, its legs backward, as it flew away, wishing she had known what Wolf had scented. The bustard would have made a wonderful meal for all three of them, with plenty left over.

"Too bad we weren't faster," Jondalar said.

Ayla noticed he was putting a light spear and his spear-thrower back in his pack basket. She nodded as she wrapped her leather sling back around her head. "I wish I had learned to use Brecie's throwing stick. It's so much faster. When we stopped by that marsh where all the birds were nesting on the way to hunt mammoths, it was hard to believe how quick she was with it. And she could get more than one bird at a time."

"She was good. But she probably practiced as long with that throwing stick as you did with your sling. I don't think that kind of skill is something to be gained in one season."

"But if this grass wasn't so tall, I might have been able to see what Wolf was going after in time to get my sling and some stones out. I thought it was probably a vole."

"We should keep our eyes open for anything else that Wolf might scare up," Jondalar said.

"I had my eyes open. I just can't see anything!" Ayla said. She looked at the sky to check the position of the sun, and she stretched up to try to see over the grass. "But you're right. It wouldn't hurt to think about getting fresh meat for tonight. I've seen all kinds of plants that are good to eat. I was going to stop and gather some, but they seem to be all over, and I'd rather do it later and have them fresh, not after they've wilted in this hot sun. We still have some of the bison roast left that we got from Feather Grass Camp, but it will only last one more meal, and there's no reason to use the dried traveling meat at this time of year, when there is plenty of fresh food around. How much longer before we stop?"
