The forest, which in the morning had been so distant from them, was now excessively close, and they had hopes of reaching it before night. They therefore took up the paddles again with fresh ardour and continued their route. At sunset the canoe disappeared beneath the immense dome of foliage of the virgin forest which the stream intersected obliquely.
At nightfall the yells of wild beasts were heard hoarsely in the depths of the forest. Leon did not consider it prudent to venture at this hour into unknown regions, which contained dangers of every description. Consequently after tacking about for some time, the captain gave orders to pull for a rocky point which jutted out into the water, and which they could approach without any difficulty. After they had landed, Leon walked round the rock in order to reconnoitre the neighbourhood, and find out in what part of the forest they were.
Chance served him better than he could have hoped for. After parting with great difficulty and extraordinary precautions the creepers and shrubs which obstructed his progress, he suddenly found himself at the entrance of a natural grotto formed by one of the volcanic convulsions so frequent in these regions.
On seeing this he stopped, and lopping with his machete a branch of the resinous tree, which the Indians call the candle tree, and which grows profusely in that part of America, he struck a light, lit the torch, and then boldly entered the grotto, followed by Wilhelm and Giacomo. The smuggler's sudden appearance startled a swarm of night birds and bats, which began flying heavily in all directions and attempting to escape.
Leon continued his march without troubling himself about these gloomy denizens, whose sports he so unexpectedly interrupted. All at once a hoarse and prolonged growl was audible in a remote corner of the grotto. The three men remained nailed to the ground. They found themselves face to face with a magnificent bear, of which the cavern was doubtless the usual abode, and which, standing on its hind legs with widely-opened mouth, showed the troublesome visitors, who had disturbed it in its retreat, a tongue red as blood, and glistening claws of a remarkable length. Its round and staring eyes were fixed on the smugglers in a way that caused them to reflect. Luckily the latter were not the men to let themselves be intimidated for long.
"There's a fellow who seems inclined to sup with us," said Giacomo, looking at the animal.
"Silence! My piece will make us, on the contrary, sup with him. Here, Giacomo, take my torch, lad."
"Take care, captain," the latter observed. "A shot fired at this spot will make a frightful din, and bring a band of red devils on our back."
"You are right, by Heaven!" the captain replied; "We must run no risk."
Then, laying his rifle along the side of the grotto, he undid the lasso which he rolled round his body.
