“The Eagle is only a trial craft. Over in the workshop yonder, I’ve got a genius of a fellow, named Morse, working for me, who is turning out the latest thing in airships. Here’s our living quarters.”

Mr. Parks led Andy into the shed-like structure that formed the back of the tent which sheltered the aeroplane and also a dirigible balloon. They passed through several partitioned-off spaces holding cots. Then there was a comfortable sitting room. Next to it was a kitchen.

This room was sizzling hot, for it held a big cooking-range, before which an aproned cook stood with an immense basting spoon in his hand. He was the blackest, fattest cook Andy had ever seen. His eyes were big with jolly fun, and his teeth gleamed white and full as he grinned and nodded.

From this and other references to the man in the shop, Andy decided that Mr. Morse must be quite a proficient mechanician. He longed to get a peep into his workshop. After dinner, however, Mr. Parks said:
