Dave helped the girl down the steps at the rear of the vehicle. He led her to the gates of the enclosure and drew one of them wide open.

“Why, it is an airship!” exclaimed Amy Winston. “I saw it yesterday from the seminary grounds.”

“Dave was running it, and I was aboard,” boasted Hiram, proudly.

“How beautifully it sailed,” murmured the girl.

“Miss Winston,” spoke Dave, “I can make Easton in about three hours in that machine. It may be something I should not propose, considering the possible risk, but the Gossamer is at your service.”

“Oh,” exclaimed Amy, her eyes filling with tears of gratitude and hope, “I would dare any danger to once more see my dear mother before she dies.”

“You are willing to try it?” asked Dave, definitely.

Amy was trembling, but she answered bravely in the affirmative.

“Tell Mr. Grimshaw,” said Dave to his friend, who at once started off to obey the order. “Now, Miss Winston,” continued the young aviator, “I will help you to a seat in the machine.”

When the girl had been disposed of in the most comfortable seat in the Gossamer, Dave gave her a strap to draw her dress skirt tightly about her feet. Other straps bound her in the seat so that by no possibility could she fall or be thrown out.
