“There she is,” I said. I turned and looked at Ev.

His mouth was hanging open.

“Hard to believe the Boohteri built it, isn’t it?”

Ev nodded without closing his mouth.

“Carson and I have this theory that they didn’t,” I said. “We think some poor species of indidges who lived here before built it, and then Bult and his pals fined them out of it.”

“It’s beautiful,” Ev, who hadn’t heard me, said. “I had no idea it was so long.”

“Six hundred kloms,” I said. “And getting longer. An average of two new chambers a year, according to C.J.’s aerials, not counting repaired breaks.”

Which meant our theory didn’t wash at all, but neither did the idea of the indidges doing all the work.

“It’s even more beautiful than the pop-ups,” Ev said, and I was going to ask him what exactly they were, but I didn’t think he’d hear that either.

I remembered the first time I’d seen the Wall. I’d only been on Boohte a week. We’d spent the whole time struggling up a draw in pouring rain and I’d spent the whole time wondering how I’d let Carson talk me into this, and we came out on top of a mesa a lot higher than what we were now, and Carson said, “There she is. All yours.”

Which got us a pursuant on incorrect imperialistic attitudes and how “Pursuant to proprietorship, planets are not owned.”

I looked over at Ev. “You’re right. It is presentable-looking.”

Bult finished writing up his fines, and we started out across it. He was still keeping close to the Tongue, and after half a klom he got out his binocs, looked through them at the water, and shook his head, and we plodded on.

It was already after noon, and I thought about getting lunch out of my pack, but the ponies were starting to drag and Ev was intent on the Wall, which was close to the Tongue here, so I waited.
