“Well, if they do, we’ll defend ourselves. We have a whole arsenal at our disposal. I don’t think those birds are so very formidable.” “Who can tell?” was the doctor’s only remark. Ten minutes later, the flock had come within gunshot, and were making the air ring with their hoarse cries. They came right toward the _Victoria_, more irritated than frightened by her presence. “How they scream! What a noise!” said Joe. “Perhaps they don’t like to see anybody poaching in their country up in the air, or daring to fly like themselves!” “Well, now, to tell the truth, when I take a good look at them, they are an ugly, ferocious set, and I should think them dangerous enough if they were armed with Purdy-Moore rifles,” admitted Kennedy. “They have no need of such weapons,” said Ferguson, looking very grave. The condors flew around them in wide circles, their flight growing gradually closer and closer to the balloon. They swept through the air in rapid, fantastic curves, occasionally precipitating themselves headlong with the speed of a bullet, and then breaking their line of projection by an abrupt and daring angle. The doctor, much disquieted, resolved to ascend so as to escape this dangerous proximity. He therefore dilated the hydrogen in his balloon, and it rapidly rose. But the condors mounted with him, apparently determined not to part company. “They seem to mean mischief!” said the hunter, cocking his rifle. And, in fact, they were swooping nearer, and more than one came within fifty feet of them, as if defying the fire-arms. “By George, I’m itching to let them have it!” exclaimed Kennedy. “No, Dick; not now! Don’t exasperate them needlessly. That would only be exciting them to attack us!” “But I could soon settle those fellows!” “You may think so, Dick. But you are wrong!” “Why, we have a bullet for each of them!” “And suppose that they were to attack the upper part of the balloon, what would you do? How would you get at them? Just imagine yourself in the presence of a troop of lions on the plain, or a school of sharks in the open ocean! For travellers in the air, this situation is just as dangerous.” “Are you speaking seriously, doctor?” “Very seriously, Dick.” “Let us wait, then!” “Wait! Hold yourself in readiness in case of an attack, but do not fire without my orders.” The birds then collected at a short distance, yet so near that their naked necks, entirely bare of feathers, could be plainly seen, as they stretched them out with the effort of their cries, while their gristly crests, garnished with a comb and gills of deep violet, stood erect with rage. They were of the very largest size, their bodies being more than three feet in length, and the lower surface of their white wings glittering in the sunlight. They might well have been considered winged sharks, so striking was their resemblance to those ferocious rangers of the deep.
