Radnal led the line of donkeys around the Bitter Lake. He was careful not to get too close to the little water actually in the lake at this time of year. Sometimes a salt crust formed over mud; a donkey’s hoof could poke right through, trapping the animal and slicing its leg against the hard, sharp edge of the crust.

After a while, the tour guide asked, “Do you have all the pictures you want?” When no one denied it, he said, “Then we’ll head back toward the lodge.”

“Hold on.” Eltsac vez Martois pointed across the Bitter Lake. “What are those things over there?”

“I don’t see anything, Eltsac,” his wife said. “You must be looking at a what-do-you-call it, a mirage.” Then, grudgingly, a heartbeat later: “Oh.”

“It’s a herd of humpless camels,” Radnal said quietly. “Try not to spook them.”

The herd was a little one, a couple of long-necked males with a double handful of smaller females and a few young ones that seemed all leg and awkwardness. Unlike the donkeys, they ambled over the crust around the Bitter Lake. Their hooves were wide and soft, spreading under their weight to keep them from falling through.

A male stood guard as the rest of the herd drank at a scummy pool of water. Golobol looked distressed. “That horrid liquid, surely it will poison them,” he said. “I would not drink it to save my life.” His round brown face screwed up in disgust.

“If you drank it, it would end your days all the sooner. But humpless camels have evolved along with the Bottomlands; their kidneys are wonderfully efficient at extracting large amounts of salt.”

“Why don’t they have humps?” Lofosa asked. “Krepalgan camels have humps.” By her tone, what she was used to was right.

“I know Krepalgan camels have humps,” Radnal said. “But the camels in the southern half of the Double Continent don’t, and neither do these. With the Bottomlands beasts, I think the answer is that any lump of fat — which is what a hump is — is a liability in getting rid of heat.”
