sinister nature of the surroundings made an impression on the Germans, and, to their surprise, on the Gauchos too. The old man and the boy talked in whispers, and the man dismounted on a number of occasions to feel the soil. They noticed that there was no grass, not the least blade, and the thistles had no leaves: they looked like coral. Clearly the region was drought stricken. The earth crumbled at a touch, yet a layer of dust did not seem to have formed, although they could not be sure, because the wind had dropped to nothing. In the mortal stillness of the air, the sounds of the horses' hooves, their own words and even their breathing were accompanied by menacing echoes. From time to time they noticed that the old guide was straining anxiously to hear something. It was contagious; they started listening too. They could hear nothing, except perhaps the faint hint of a buzzing that must have been mental. The guide clearly suspected something, but a vague fear prevented them from questioning him.
For a day and a half they advanced through that terrifying void. Not a bird to be seen in the sky, no guinea pigs or rheas or hares or ants on the ground. The planet's peeling crust seemed to be made of dried amber. When they finally came to a river where they could take on water, the guide's suspicions were confirmed. He solved the enigma, which was especially perplexing there on the river banks: not only were they devoid of the least living cell of vegetation, the numerous trees, mainly willows, had been stripped of all their leaves, as if a sudden winter had plucked them bare for a joke. It was an impressive spectacle: livid skeletons, as far as the eye could see, not even trembling. And it was not that their leaves had fallen, for the ground was pure silica.
Locusts. The biblical plague had passed that way. That was the solution, revealed to them at last by the guide. If he had delayed doing so, it was only because he wanted to be sure. He had recognized the signs by hearsay, never having seen them with his own eyes. He had also been told about the sight of the swarm in action, but preferred not to talk about that, because it sounded fanciful, though, considering the results, fancy could hardly have outstripped the facts. Alluding to his friends disappointment at having missed the Indians, Krause asked if he did not regret having arrived too late on this occasion too. Rugendas imagined it. A green field, suddenly smothered by a buzzing cloud, and, a moment later, nothing. Could a painting capture that? No. An action painting, perhaps.
They proceeded on their way, wasting no time. It was idle to wonder which direction the swarm had taken, because the area affected was too large. They had to concentrate on getting to San Luis, and try to enjoy themselves in the meantime, if they could. It was all experience, even if they had missed out by minutes. The residual vibration in the atmosphere had an apocalyptic resonance.
As it turned out, a number of practical problems made it hard for the painters to enjoy themselves. That afternoon, after two days of involuntary fasting, the horses reached the limits of their endurance. They became uncontrollable, and there was no choice but to stop. To make things worse, the temperature had continued to rise, and must have been near one hundred and twenty two degrees. Not an atom of air was moving. The barometric pressure had plummeted. A heavy ceiling of grey clouds hung over their heads, but without affording any relief from the glare, which went on blinding them. What could they do? The young cook was frightened, and kept clear of the horses as if they would bite him. The old man would not raise his eyes, ashamed of his failure as a guide.There were attenuating circumstances: this was the first time he had crossed an area stricken by a plague of locusts. The Germans conferred in whispers. They were in a lunar ocean, rimmed around with hills. Krause was in favor of grinding up some biscuits,
