The little wings soon ceased to move, and both bird and spider fell to the end of the thread, where they hung for a moment suspended. The boys could see that the bird was dead, and the mandibles of the tarantula were buried in its shining threat!
François would have rushed forward to kill the destroyer; but Lucien, who was too ardent a naturalist to have his lesson thus interrupted, restrained his more impetuous brother, and all three remained quiet as before.
The tarantula now commenced reeling in his line, for the purpose of carrying his prey up among the branches, where he had his nest. The boys looked upward to discover the latter. There, sure enough, was the web, in a shaded corner, stretching its meshes from a large liana to the trunk of the tupelo; and towards this point the spider now slowly progressed with his lifeless victim.
As they watched his motions, their eyes were caught by a shining object that moved along the wrinkled bark of the liana. As the vine was nearly a foot in diameter, and of a deep ferruginous colour, this object was the more apparent against its dark ground, for it was a creature of brilliant hues. It was an animal of the lizard species; and if any lizard could be considered beautiful, this one might have been so called. But the hideous, half-human form of these animals, their piercing looks, their stealthy and predatory habits, and, above all, the knowledge that the bite of several of their species is poisonous, combine to render them objects that excite disgust and awe, rather than admiration.
This one, as we have already said, was of the most brilliant colour. The whole of its upper surface was a golden green, vivid as the hues of an emerald; while its body underneath was greenish-white. But this part, as it lay along the liana, was not seen; and a pure, uniform green was the apparent colour of the whole animal. There was one conspicuous exception—the throat. This was swollen out, as though by inflation, exhibiting a surface of the brightest scarlet, that appeared in the sun as if painted with vermilion. The eyes of the animal shone like flame—for the irides were, in fact, the colour of burnished gold, with small pupils, sparkling like diamonds, in their midst. Its arms and limbs were of the same colour as the body; and its branching feet exhibited the peculiarity of having small knots or tubercules at the ends of the toes. These tubercules, together with the loose dewlap of the throat, told the genus to which the animal belonged,—an anolius of the family Iguanidae, and the only species of the anolius found in the territory of the United States.
These facts were communicated by Lucien to his brothers in a whisper, while they were observing the creature on the liana. Basil and François had often seen the species before, and were familiar with it under the names of “green lizard” and “chameleon,”—both of which names are applied to it in common phraseology. The animal was not over six inches in length; and its long coffin-shaped head, and slender, whip-like tail, were at least two-thirds of this extent. When first noticed, it was passing up the liana, for the latter slanted upwards between the trees. It did not see the boys; or, at all events, did not regard their presence—for the chameleon is a bold little animal, and is not afraid of man. Up to this time it had not seen the tarantula either. As it was passing onward, its eyes fell upon the latter as he climbed up his silken ladder. All at once the lizard stopped, and put itself into a crouching attitude. Its colour suddenly changed. The vermilion throat became white, and then ashy pale; and the bright green of its body faded into dark brown or rust colour, until it was difficult to distinguish the animal from the bark of the liana! Had the eyes of the spectators not been already fixed upon it, they might have supposed that it had disappeared altogether. After crouching for a few seconds, it seemed to have formed its plan of attack—for it was evident that it meant to attack the spider—such, with flies and other insects, being its natural food and prey. It passed to the opposite side of the liana, and then proceeded upward, making for the nest of the tarantula. It reached this point by a single run, although its back was downward as it crawled. This it could easily do by means of the tubercules upon its toes—which enable lizards of the genus anolius to walk upon perpendicular walls, up glass windows, or along the smoothest ceilings.
For some moments it lay quiet in a crouching attitude, waiting the approach of the spider, that, busied with his own affairs, did not dream of a lurking foe so near him. The tarantula was, no doubt, in high spirits at the moment, exulting at the prospect of the banquet of blood he should have, when he had carried the ruby-throat to his dark, silken cave. But he was destined never to reach that cave. When he had got within a few inches of its entrance, the chameleon sprang out from the limb, seized the spider in his wide jaws, and all three—lizard, spider, and bird—came to the ground together. The bird was let go in the fall, and became separated from the others. Between these there was a short struggle over the grass—for the tarantula fought fiercely; but he was no match for his antagonist; who, in a few moments, had ground off his legs with his powerful jaws, and left him a helpless and motionless trunk. The chameleon now seized his victim by the head, sunk his sharp, conical teeth into its skull, and thus killed it outright.
What appeared singular to all was, that the moment the lizard had first sprung upon his prey his bright colours returned like a flash, and he again appeared with his green back and red throat, if possible more brilliant than ever.
He now commenced dragging the body of the spider over the grass, evidently making for some decayed logs, half covered with vines and briars, that formed a heap near the spot. Here, no doubt was his retreat.
This time François did not attempt to interfere. He had no desire to do so. He looked upon the death of the tarantula as a just punishment; moreover, the chameleon, from its fine colours, its sportive habits, and its harmlessness—so far as man is concerned—is a general favourite with all; and it was so with François. In fact, François, as well as his brothers, who had often watched this little creature gambolling among the leaves, and feeding upon flies and other small insects, had never seen it exhibit so much ferocity before. Notwithstanding this, they all applauded it for killing the hideous tarantula; and so far as they were concerned, it might have carried the body to its hole without being molested. It was destined, however, to meet with interruption from another quarter. François, whose quick eyes were wandering about, suddenly exclaimed,—
