The red-whiskered policeman keeled over quite gracefully and fell across the body of the dog, while Rob continued to mount upward until he was out of sight of those in the streets.
"That was a narrow escape," he thought, breathing more freely. "I hated to paralyze that policeman, but he might have sent a bullet after me. Anyhow, he'll be all right again in an hour, so I needn't worry."
It was beginning to grow dark, and he wondered what he should do next. Had he possessed any money he would have descended to the town and taken a bed at a hotel, but he had left home without a single penny. Fortunately the nights were warm at this season, so he determined to travel all night, that he might reach by morning some place he had never before visited.
Cuba had always interested him, and he judged it ought to lie in a southeasterly direction from Boston. So he set the indicator to that point and began gliding swiftly toward the southeast.
He now remembered that it was twenty-four hours since he had eaten the first electrical tablet. As he rode through the air he consumed another. All hunger at once left him, while he felt the same invigorating sensations as before.
After a time the moon came out, and Rob amused himself gazing at the countless stars in the sky and wondering if the Demon was right when he said the world was the most important of all the planets.
But presently he grew sleepy, and before he realized what was happening he had fallen into a sound and peaceful slumber, while the indicator still pointed to the southeast and he continued to move rapidly through the cool night air.
5. The Cannibal Island
Doubtless the adventures of the day had tired Rob, for he slept throughout the night as comfortably as if he had been within his own room, lying upon his own bed. When, at last, he opened his eyes and gazed sleepily about him, he found himself over a great body of water, moving along with considerable speed.
"It's the ocean, of course," he said to himself. "I haven't reached Cuba yet."
It is to be regretted that Rob's knowledge of geography was so superficial; for, as he had intended to reach Cuba, he should have taken a course almost southwest from Boston, instead of southeast. The sad result of his ignorance you will presently learn, for during the entire day he continued to travel over a boundless waste of ocean, without the sight of even an island to cheer him.
The sun shone so hot that he regretted he had not brought an umbrella. But he wore a wide-brimmed straw hat, which protected him somewhat, and he finally discovered that by rising to a considerable distance above the ocean he avoided the reflection of the sun upon the water and also came with the current of good breeze.
Of course he dared no stop, for there was no place to land; so he calmly continued his journey.
"It may be I've missed Cuba," he thought; "but I can not change my course now, for if I did I might get lost, and never be able to find land again. If I keep on as I am I shall be sure to reach land of some sort, in time, and when I wish to return home I can set the indicator to the northwest and that will take me directly back to Boston."
This was good reasoning, but the rash youth had no idea he was speeding over the ocean, or that he was destined to arrive shortly at the barbarous island of Brava, off the coast of Africa. Yet such was the case; just as the sun sank over the edge of the waves he saw, to his great relief, a large island directly in his path.
He dropped to a lower position in the air, and when he judged himself to be over the center of the island he turned the indicator to zero and stopped short.
The country was beautifully wooded, while pretty brooks sparkled through the rich green foliage of the trees. The island sloped upwards from the sea-coast in all directions, rising to a hill that was almost a mountain in the center. There were two open spaces, one on each side of the island, and Rob saw that these spaces were occupied by queer-looking huts built from brushwood and branches of trees.
