"To the links," said Mercury, and with a sudden chug-chug, and a jerk which nearly threw me out of the conveyance, we were off. And what a ride it was! At first the sensation was that of falling, and I clutched nervously at the sides of the skitomobile, but by slow degrees I got used to it, and enjoyed one of the most exhilarating hours that has ever entered into my experience.

Planet after planet was passed as we sped on and on upward, and as my delight grew I gave utterance to it.

"Jove! But this is fine!" I said. "I never knew anything like it, except looping the loop."

Phaeton grinned broadly and winked at Jason.

"How would you like to loop the loop out here?" the latter asked.

"What? In a machine like this?" I cried.

"Certainly," said Jason. "It's great sport. Give him the twist, Phaeton."

I began to grow anxious again, for I recalled the past careless methods of Phaeton, and I had no wish to go looping the loop through the empyrean with one of his known adventurous disposition, to be hurled unceremoniously sooner or later perhaps into the sun itself.

"Perhaps we'd better leave it until some other day," I ventured, timidly.

"No time like the present," Jason retorted. "Only hang on to yourself. All ready, Phaety!"
