Some of the game Andy had killed was soon on the table, for Washington, in addition to his other accomplishments, was an expert cook. During the evening the boys and their friends sat in the living room of the big shed and talked over the events of the day.

Sunday was spent in discussing what adventures might lie before them should they be able to descend into the big hole. Washington did not say much, but it was easy to see he had no notion of going. He even began to pack his few belongings in readiness to leave the service of Mr. Henderson, for whom he had worked a good many years.

No one remained long abed Monday morning. Even Washington was up early in spite of the interest he had lost in the professor’s voyage.

“I jest wants t’ see yo’ start fer that place where they buries live folks,” he said.

In order to properly test the Flying Mermaid it was necessary to move the craft from the shed from which place it had never been taken since it’s construction was started. It had been built on big rollers in anticipation of this need, so that all which was now necessary was to open the doors at the end, and roll the craft out.

This was accomplished with no small amount of labor, and it was nearly noon before the big ship was moved into the open. It was shoved along to a little clearing in front of the shed, where no trees would interfere with its possible upward movement.

Everyone was bustling about. The professor was busiest of all. He went from one machine to another; from this apparatus to that, testing here, turning wheels there, adjusting valves and seeing that all was in readiness for the generating of the powerful gas.

As the airship was half round on the bottom and as it rested in a sort of semi-circular cradle; it brought the entrance some distance above the ground. To make it easier to get in and out while preparations for the trial were going on, Bill and Tom had made an improvised pair of steps, which were tied to the side of the ship with ropes.

Up and down these the professor, the boys and Andy went, taking in tools and materials, and removing considerable refuse which had accumulated during the building of the craft.

Finally all was in readiness for starting the making of the gas. The ship was not wholly complete and no supplies or provisions for the long voyage had been taken aboard. The Flying Mermaid was about a ton lighter than it would be when fully fitted out, but to make up for this the professor had left in the ship a lot of tools and surplus machinery so that the craft held as much weight as it would under normal conditions. If the gas lifted it now it would at any other time.
