"Yes, there is!" cried Tom, eagerly.
"How?"
"The same way I came—in the aeroplane! Dr. Hendrix you must go back with me! It's the only way to save my father's life. Come with me in the Humming-Bird. It's perfectly safe. I can make the trip in less than an hour. I can carry you and your instruments. Will you come? Won't you come to save my father's life?" Tom was fairly pleading now.

"Don't be afraid, there's really no danger," said Tom.

Tom's heart gave a bound of hope.
