Really, I was amazed. It seemed to be either a special dispensation of Providence or an invention of Hawkins' which really worked.

A minute or two later he had labored back to my side, up the stairs, with the aerial fire-escape on his back.

“There!” he exclaimed. “What do you think of that?”

“It certainly seems to be a success.”

“Well, rather! Now come up to the roof and have a drop with me. We'll go into the street this time, and——”

“Thank you, Hawkins,” I said, positively. “Don't count me in on that. I'll wait for the fire before dabbling with your Anti-Fire-Fly.”

“Oh, well, come with me, anyway. I'm going down once more. You've no idea of the sensation.”

It was a considerable feat of engineering to persuade the Anti-Fire-Fly into passing through the scuttle, but Hawkins finally accomplished it, and pushed the contrivance to the edge of the roof.

“Now that thing will carry a small family with ease and safety,” he said proudly. “Just sit down in the basket and feel the roominess. Oh, don't be afraid. I'll come, too.”

“Yes, it's very nice,” I said somewhat nervously, after crouching beside him for a moment. “I think I'll get out now.”
