They did get everything in, though their saddlebags bulged like a snake that had just swallowed a half-grown humpless camel. A couple of other people stood around helplessly, with full bags and gear left over. Smiling a smile he hoped was not too predatory, Radnal took them to the scales and collected a tenth of a unit of silver for every unit of excess weight.

“This is an outrage,” the dark brown Highhead man said. “Do you know who I am? I am Moblay Sopsirk’s son, aide to the Prince of Lissonland.” He drew himself up to his full height, almost a Tarteshan cubit more than Radnal’s.

“Then you can afford the four and three tenths,” Radnal answered. “I don’t keep the silver. It all goes to upkeep for the park.”

Grumbling still, Moblay paid. Then he stomped off and swung aboard his animal with more grace than Radnal had noticed him possessing. Down in Lissonland, the guide remembered, important people sometimes rode stripehorses for show. He didn’t understand that. He had no interest in getting onto a donkey when he wasn’t going down into Trench Park. As long as there were better ways of doing things, why not use them?

Also guilty of overweight baggage were a middle-aged Tarteshan couple. They were overweight themselves, too, but Radnal couldn’t do anything about that. Eltsac vez Martois protested, “The scale at home said we were all right.”

“If you read it right,” Nocso zev Martois said to her husband. “You probably didn’t.”

“Whose side are you on?” he snarled. She screeched at him. Radnal waited till they ran down, then collected the silver due the park.

When the tourists had remounted their donkeys, the guide walked over to the gate on the far side of the corral, swung it open, and replaced the key in a pouch he wore belted round his waist under his robe. As he went back to his own animal, he said, “When you ride through there, you enter the park itself, and the waivers you signed come into play. Under Tarteshan law, park guides have the authority of military officers within the park. I don’t intend to exercise it any more than I have to; we should get along just fine with simple common sense. But I am required to remind you the authority is there.” He also kept a repeating handcannon in one of his donkey’s saddlebags, but didn’t mention that.

“Please stay behind me and try to stay on the trail,” he said. “It won’t be too steep today; we’ll camp tonight at what was the edge of the continental shelf. Tomorrow we’ll descend to the bottom of the ancient sea, as far below mean sea level as a medium-sized mountain is above it. That will be more rugged terrain.”

The Strongbrow woman said, “It will be hot, too, much hotter than it is now. I visited the park three or four years ago, and it felt like a furnace. Be warned, everyone.”

“You’re right, freelady, ah-” Radnal said.

“I’m Toglo zev Pamdal.” She added hastily, “Only a distant collateral relation, I assure you.”

“As you say, freelady.” Radnal had trouble keeping his voice steady. The Hereditary Tyrant of Tartesh was Bortav vez Pamdal. Even his distant collateral relations needed to be treated with sandskink gloves. Radnal was glad Toglo had had the courtesy to warn him who she was-or rather, who her distant collateral relation was. At least she didn’t seem the sort who would snoop around and take bad reports on people back to the friends she undoubtedly had in high places.

Although the country through which the donkeys ambled was below sea level, it wasn’t very far below. It didn’t seem much different from the land over which the tourists’ omnibus had traveled to reach the edge of Trench Park: dry and scrubby, with thornbushes and palm trees like long-handled feather dusters.

Radnal let the terrain speak for itself, though he did remark, “Dig a couple of hundred cubits under the soil hereabouts and you’ll find a layer of salt, same as you would anywhere in the Bottomlands. It’s not too thick here on the shelf, because this area dried up quickly, but it’s here. That’s one of the first clues geologists had that the Bottomlands used to be a sea, and one of the ways they map the boundaries of the ancient water.”

Moblay Sopsirk’s son wiped his sweaty face with a forearm. Where Radnal, like any Tarteshan, covered up against the heat, Moblay wore only a hat, shoes, and a pocketed belt to carry silver, perhaps a small knife or toothpick, and whatever else he thought he couldn’t do without. He was dark enough that he didn’t need to worry about skin cancer, but he didn’t look very comfortable, either.

He said, “Were some of that water back in the Bottomlands, Radnal, Tartesh would have a better climate.”

“You’re right,” Radnal said; he was resigned to foreigners using his familial name with uncouth familiarity.

“We’d be several hundredths cooler in summer and warmer in winter. But if the Barrier Mountains fell again, we’d lose the great area that the Bottomlands encompass and the mineral wealth we derive from them: salt, other chemicals left by evaporation, and the petroleum reserves that wouldn’t be accessible through deep water. Tarteshans have grown used to heat over the centuries. We don’t mind it.”

“I wouldn’t go that far,” Toglo said. “I don’t think it’s an accident that Tarteshan air coolers are sold all over the world.”

Radnal found himself nodding. “You have a point, freelady. What we get from the Bottomlands, though, outweighs fuss over the weather.”

As he’d hoped, they got to the campsite with the sun still in the sky and watched it sink behind the mountains to the west. The tourists gratefully descended from their donkeys and stumped about, complaining of how sore their thighs were. Radnal set them to carrying lumber from the metal racks that lined one side of the site.

He lit the cookfires with squirts from a squeeze bottle of starter fuel and a flint-and-steel lighter. “The lazy man’s way,” he admitted cheerfully. As with his skill on a donkey, that he could start a fire at all impressed the tourists. He went back to the donkeys, dug out ration packs which he tossed into the flames. When their tops popped and began to vent steam, he fished them out with a long-handled fork.

“Here we are,” he said. “Peel off the foil and you have Tarteshan food — not a banquet fit for the gods, perhaps, but plenty to keep you from starving and meeting them before your time.”

Evillia read the inscription on the side of her pack. “These are military rations,” she said suspiciously. Several people groaned.

Like any other Tarteshan freeman, Radnal had done his required two years in the Hereditary Tyrant’s Volunteer Guard. He came to the ration packs’ defense: “Like I said, they’ll keep you from starving.”

The packs — mutton and barley stew, with carrots, onions, and a heavy dose of ground pepper and garlic — weren’t too bad. The two Martoisi inhaled theirs and asked for more.

“I’m sorry,” Radnal said. “The donkeys carry only so many. If I give you another pack each, someone will go hungry before we reach the lodge.”

“We’re hungry now,” Nocso zev Martois said.

“That’s right,” Eltsac echoed. They stared at each other, perhaps surprised at agreeing.

“I’m sorry,” Radnal said again. He’d never had anyone ask for seconds before. Thinking that, he glanced over to see how Toglo zev Pamdal was faring with such basic fare. As his eyes flicked her way, she crumpled her empty pack and got up to throw it in a refuse bin.

She had a lithe walk, though he could tell little of the shape of her body because of her robes. As young — or even not so young — men will, he wandered into fantasy. Suppose he was dickering with her father over bride price instead of with Markaf vez Putun, who acted as if his daughter Wello shat silver and pissed petrol…

He had enough sense to recognize when he was being foolish, which is more than the gods grant most. Toglo’s father undoubtedly could make a thousand better matches for her than a none-too-special biologist. Confrontation with brute fact didn’t stop him from musing, but did keep him from taking himself too seriously.
