The mule, however, soon recovered, but from that time forward, no coaxing, nor leading, nor driving, nor whipping, nor pushing, would induce that same mule to go within twenty feet of the bank of that same piece of water.
Guapo now bethought himself of the narrow escape he himself had had while swimming across to the palm-woods; and the appearance of the gymnotus only rendered him more determined to keep the promise he had made to Leon,—that is, that he would revenge him of the caribes.
None of them could understand how Guapo was to get his revenge without catching the fish, and that would be difficult to do. Guapo, however, showed them how on the very next day.
During that evening he had made an excursion into the wood, and returned home carrying with him a large bundle of roots.
They were the roots of two species of plants—one of the genus Piscidea, the other a Jacquinia. Out of these, when properly pounded together, Guapo intended to make the celebrated “barbasco,” or fish-poison, which is used by all the Indians of South America in capturing fish. Guapo knew that a sufficient quantity of the barbasco thrown into the water would kill either “temblador,” caribe, or any fish that ever swam with fins.
And so it proved. In the morning Guapo having prepared his barbasco, proceeded to the upper end of the lake-like opening of the river, and there flung his poison into the stream. The slow current through the valley greatly favoured him, and from the large quantity of roots he had used, the whole pool was soon infected with it. This was seen from the whitish tinge which the water assumed. The barbasco had scarcely time to sink to the bottom when small fish were seen coming to the surface, and turning “wrong side uppermost.” Then larger ones appeared, and in a few minutes all the fish in that particular stretch of water, with several gymnoti, were seen floating on the surface quite dead. To the great joy of Guapo and Leon, who sat by the bank watching, hundreds of the little caribes, with their bronze gills quite open, and their yellow bellies turned up, were seen among the rest.
But Guapo had not made this great slaughter purely out of revenge. He had another object. They were not too well off for meat, and a dish of fish would be welcome. Guapo and Don Pablo had already provided themselves with long-handled nets, and they soon scooped out several basketfuls of fish. Among others they netted numerous “caribes,” for these little monsters, fierce as they are, are not surpassed for delicacy of flavour by any fish in the South American rivers. The gymnoti approached the bank, where Guapo fished them out, not to eat—although they are often eaten. There was not a spark of electricity in them now. The barbasco had cured them of that; any one might have handled them with safety, as there was not a charge left in their whole battery.
The lake was quite cleared of all its dangerous denizens, and Leon might bathe with safety, as soon as he got well; and over the fish-dinner they could now laugh at the adventures both of Leon and the electrified mule.
