"So high? Oh, it will be dangerous," she cried. "Please do not go up in it, Carson."

"It will be very safe," I assured her, "much safer than incurring the dangers of the forests on foot. No savage beasts or men can harm the voyager in an airship."

"But think of being 'way up above the trees!" she said with a little shudder.

"I shall fly even higher than that," I told her. "I shall fly over the loftiest mountains."

"But you will never fly over the great trees of Amtor; I know that."

She referred to the gigantic trees that raise their tips five thousand feet above the surface of Amtor to drink the moisture from the inner cloud envelope.

"Yes; possibly I shall fly even above those," I replied, "though I will admit that flying blind in that solid bank of clouds does not appeal to me."

She shook her head. "I shall be afraid every time I know that you are up in the thing."

"Oh, no you won't, not after you are familiar with it. Some day soon I am going to take you up with me."

"Not me!"
