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."
