“We don’t know. Nobody’s ever seen them doing it,” Carson said. “Or seen them doing anything worthwhile,” he added darkly, watching Bult tallying up, “like finding us a way across it so we can get on with this expedition.”

He went over to Bult and started talking to him in an inappropriate manner.

“And what are they?” Ev asked. “Dwellings?”

“And storerooms for all the stuff Bult buys, and landfills. Some of them are decorated, with flowers hanging in the opening and nibbler bones laid out in a design in front of the door. Most of them stand empty.”

Carson stomped back, his mustache quaking. “He says we can’t cross here either.”

“The other break’s been repaired, too?” I said.

“No. Now he says there’s something in the water. Tssi mitss.”

I looked over at the Tongue. It was flowing over quartzite sand here and was clear as glass. “What’s that?”

“Your guess is as good as mine. It translates as ‘not there.’ I asked him how much farther we have to go, and all he’ll say is ‘sahhth.’ ”

Sahhth apparently meant halfway to the Ponypiles because he didn’t even glance at the Tongue again once we had the ponies up and moving, and he didn’t even bother to lead. He motioned Ev and me ahead, and went back to ride with Carson.

Not that we could get lost. We’d charted all this territory before, and all we had to do was keep close to the Tongue. The Wall dipped away from the water and off toward a line of mesas, and we went up a hill through a herd of luggage, grazing on dirt, and came out at another Scenic Point.

The thing about these long vistas is that you’re not going to see anything else for a while, and we’d already catalogued the f-and-f along here. There weren’t any, anyway—a lot of luggage, some tinder grass, an occasional roadkill. I ran geological contours and double-checked the topographicals, and then, since Ev was busy gawking at the scenery, ran the whereabouts.
