On the narrowest point of the isthmus, just where it joins the mainland, and where a sheltered bay runs up from either sea, is situated the great city of Amakasfe, the natural centre of Martial life and commerce.

At this point we found awaiting us the balloon which was to convey us to the Court of the Suzerain.

A very light but strong metallic framework maintained the form of the "fish-shaped" or spindle-shaped balloon itself, which closely resembled that of our vessel, its dimensions being of necessity greater.

Attached to this framework was the car of similar form, about twelve feet in length and six in depth, the upper third of the sides, however, being of open-work, so as not to interfere with the survey of the traveller.

Eveena could not help shivering at the sight of the slight vehicle and the enormous machine of thin, bladder-like material by which it was to be upheld.
