The men gaped at one another. A growl drummed underneath them, drummed at the palmera, rattled rocks and seemed, somehow, part of both earth and sky. Raul felt the sand give underneath him and sprang up, revolver in hand. The palm next to him, a tree many years old, leaned over, and then the growl passed farther away and disappeared.

"That was a bad one," Manuel said.

"The volcano," said Raul.

Another shock reached them as they ate their iguana: the sand heaved, palms waved like flags; numbness hung in the air; the sun died out; birds cried as though in pain. A full-grown tigre rushed past Manuel, crazed with fear. His plunge sent up a flock of birds that cackled insanely.

"Let's get where we can see the volcano," said Raul, stuffing his mouth.

"Listen," said Manuel.

A volcanic explosion sounded like air passing through a bamboo tube.

"I'll see about the horses," cried Manuel.

They were yanking at their ropes as Manuel raced toward them, whacking foliage aside, hoping he could get to them before they broke away. He tied them to a ceiba, where they had some sort of forage.

Another explosion told Raul the volcano had let loose; he planned to push through the palmera to the closest hill and take stock of the eruption. With his hunting knife, he sliced more iguana and, putting on his hat, lunged after Manuel. Rolling their eyes and snuffing, the horses dragged at their reins and kicked. Raul grabbed Chico, and handed Manuel a chunk of meat.
