And despite the downpour, the deafening thunder and the lightning that seemed ready to sear one's eyes, he walked out of the cave entrance, followed by Tom and the others.
"Come on!" cried Tom, in a voice he tried to render confident, as they went out into the terrible storm. "We'll beat 'em yet!"
The rain fell harder than ever. Small torrents were now rushing down the trail, and it was only a question of a few minutes before the place where they stood would be a raging river, so quickly does the rain collect in the mountains and speed toward the valleys.
"We must take to the forest!" cried Tom. "There'll be some shelter there, and I don't like the way the geography of this place is behaving. There may be a landslide at any moment."
As he spoke he motioned upward through the mist of the rain to the sloping side of the mountain towering above them. Loose stones were beginning to roll down, accompanied by patches of earth loosened by the water. Some of the patches carried with them bunches of grass and small bushes.
"Yes, it will be best to move into the jungle," said the professor. "Goosal, you had better take the lead."
It was wonderful to see how well the aged Indian bore up in spite of his years, and walked on ahead. They had left their mules tethered some distance back, in a sheltering clump of trees, and they hoped the animals would be safe.
The guide found a place where they could leave the trail, though going down a dangerous slope, and take to the forest. As carefully as possible they descended this, the rain continuing to fall, the wind to blow, the lightning to sizzle all about them and the thunder to boom in their ears.
They went on until they were beneath the shelter of the thick jungle growth of trees, which kept off some of the pelting drops.
"This is better!" exclaimed Ned, shaking his poncho and getting rid of some of the water that had settled on it.
