The result of this labor was the construction of three hollow body-helmets of asbestos, held away from the skin of the body so that air could percolate between the asbestos and their bodies. Air helmets for their heads were also made of asbestos. In addition to this, they covered their gliders with asbestos. Over all Epworth spread a coat of aluminum.

Thus prepared they flew again to the South Pole. Moawha went with them.

“I am not going to let my good friends leave me as long as I can see them,” she assured them. “Maybe you will have to come back again. I hope so. But if you do not you shall know that Moawha loves you, and wants you with her.”

It was a solemn parting. They left Moawha standing on the shady side of Mount Leibnitz’ peak waving her hand at them, and crying softly.

All three sprang into the air at the same time. Epworth jockeyed his glider near to Joan, and pointed upward. Upward meant straight into a blazing sun without any signs of land around them until they passed out of the crater.

“That for the heat!” shouted Billy when he got up into the glare of the sun, and discovered that the improvised protection would in a way answer the purpose. “I can stand a little heat.”

But he had no idea of the heat he would have to stand. Soon he discovered that he had spoken joyfully too soon.

It was an endless fiery furnace. Hour after hour they circled upward and outward. The hole in Mount Leibnitz proved of enormous size; the heat was greater than any they had ever encountered.

Fortunately Epworth had brought his binoculars with him, and using these, and his natural orientation, he was able to keep near the western line of the crater and know when they had left the inner part of the moon and had gained the outer portion.

Then began another long, wearisome journey, traveling over the surface of the moon without a compass. Putting the sun to their backs the three flew on, and on and on. But to give all the details of that terrible trip through blinding, blazing heat would necessitate a volume. They found some diminution in the heat after leaving the crater of Mount Leibnitz. Had it not been so they would never have accomplished their journey.
