“An immense snake!” shouted Tom. “It’s wound around a tree, and partly twined around the ship! That’s why we couldn’t go up! I’m going to shoot it.”
They looked to where he pointed, and there, in the glare of the light, could be seen an immense python, fully twenty-five feet long, the forward part of its fat ugly body circled around the slender prow of the airship, while the folds of the tail were about a big tree.
Tom Swift raised his electric rifle, took quick aim, and, having set it to deliver a moderate charge, pressed the button. The result was surprising, for the snake being instantly killed the folds uncoiled and the ship shot upward, only, instead of rising on an even keel, the bow pointed toward the sky, while the stern was still fast to the earth. Tilted at an angle of forty-five degrees the Black Hawk was in a most peculiar position, and those standing on the deck began to slide along it.
“There’s another snake at the stern!” cried Mr. Damon as he grasped a brace to prevent falling off. “Bless my slippers! it’s the mate of the one you killed! Shoot the other one, Tom!”
The young inventor needed no urging. Making his way as best he could to the stern of the airship, he killed the second python, which was even larger than the first, and in an instant the Black Hawk shot upward, this time level, and as it should be. Things on board were soon righted, and the travelers could stand upright. High above the black jungle rose the craft, moving forward under the full power of the propellers, until Tom rushed into the engine room, and reduced speed.
“Well, talk about things happening!” exclaimed Ned, when they had somewhat recovered from the excitement. “I should say they were beginning with a vengeance!”
“That’s the way in Africa,” declared Mr. Durban. “It’s a curious country. Those pythons generally go in pairs, but it’s the first time I ever knew them to tackle an airship. They probably stay around here where there is plenty of small game for them, and very likely they merely anchored to our craft while waiting for a supper to come along.”
“It was a very odd thing,” said Tom. “I couldn’t imagine what held us. After this I’ll see that all is clear before I try to go up. Next time we may be held by a troop of baboons and it strains the machinery to have it pull against dead weight in that way.”
However, it was found no harm had resulted from this experience, and, after reducing the gas pressure, which was taking them too high, Tom set the automatic rudders.
“We’ll keep on at slow speed through the night,” he explained, “and in the morning we’ll be pretty well into the interior. Then we can lay our course for wherever we want to go. Where had we better head for?”
