In due course of time the Gulf of Mexico was crossed, and one day Captain Nicodemus sighted Key West.
The voyagers could not refrain from a jolly cheer at the sight of their native land.
Soon the air-ship was sailing over the great swamps of Okeechobee, and then swept over the great orange groves and plantations of the sandy state. Georgia, South and North Carolina followed.
Along the Atlantic coast the voyagers journeyed until finally the mouth of the Chesapeake came into view, and later the Potomac. Then they hung over the Capitol city and steered west for Readestown.
The great journey was ended.
The Transient Lake and the mysterious country had been visited and were now history in the minds of the aerial voyagers. They had also brought home some of the gold.
All were satisfied and this was enough. Captain Nicodemus embraced Frank gratefully for this, his last voyage. Then he returned to his home.
Frank Reade, Jr., Barney and Pomp are yet in Readestown. The young inventor is studying up new things which we may hear from at some future day.
THE END.
