“Suppose you do it?”

“I’ll take my turn wid Harv.”

“Very well; when the night is a little farther along, Bunk, you may go out there and stand guard till say about midnight; then come to the house and wake up Harvey, and he will take his turn at playing sentinel.”

“That soots me,” Bunk was quick to say, knowing it would be much easier to keep awake during the first half of the night. So, while the others chatted as the evening wore on, the colored youth rose, yawned, stretched his arms and announced that he would go to his home not far off, tell Mr. Hartley and his wife of the arrangement and then assume his duties at the hangar.

Although he saw no call for all this extra care, Harvey was quite willing to divide the duty with his colored friend, but he meant that Bunk should come to the house and rouse him, for he could not be expected to stay awake. However, the young aviator dreamed so much of flying through the air, and was so absorbed with the entrancing scheme, that he was the first one to wake in his home. He sprang out of bed, as the sun was creeping up the horizon, and lost no time in hurrying out to the hangar to learn why Bohunkus had not called him, though he held a strong suspicion of the real reason.

As Harvey sped around the corner of the low, flat structure, the first object upon which his eyes rested was Bohunkus, stretched out on his back, his mouth open, and breathing loudly, as no doubt he had been doing through most of the night. Harvey left him lying where he was, and rejoined his folks with the story of what he had seen.

An hour later, Professor Sperbeck, accompanied by the merchant and Harvey, walked to the hangar to resume the instruction of the previous day. In the interval, Bohunkus had awakened and gone for his breakfast. He said nothing of his remissness and his friends did not refer to it, since they had more serious matters to hold their attention.

Mr. Hamilton was much pleased with the proficiency shown by his son, but did not stay long, since important business called him to the city. The day was a busy one for the young aviator, who was allowed to make a flight in the afternoon with the watchful Professor seated behind him. He had very few suggestions to make.

When Harvey came down to earth, he bumped rather energetically, but no harm was done, and on the third trial no criticism was made. Two more days were spent in practice and then the instructor said:

“You are prepared to make as long a voyage through the air as you wish, and without any assistance from me.”
