Dave Innes had this in mind when he went north. It would be well to teach Fash a lesson and, perhaps, place on the throne of Suvi a man loyal to the Empire.

Sari is not on the sea coast; so the party marched to Greenwich , a hundred and fifty miles, and there took one of the ships of the Navy, which had been built under Perry's direction. Greenwich was established and named by Dave Innes and Abner Perry. Through it passes the prime meridian of Pellucidar, also an invention of Innes and Perry.

From Greenwich , they sailed to Amoz in the EPS Sari. The EPS is a conceit of Perry's. It means Empire of Pellucidar ship, like USS California. The Sari, like most of the ships of Pellucidar, was manned by red-skinned Mezops from the Island of Anoroc , a seafaring race of fighting men. They had known only canoes until Perry and Innes introduced them to sails, but they soon mastered the new ships and learned what little of navigation Dave Innes could teach them—all dead reckoning, with only crude compasses to aid them.

Beneath a stationary sun, without the aid of stars or moon, there can be few navigational aids. The Mezops knew all there was to know about tides and currents in the coastal waters near their island. Innes and Perry gave them the compass, the log, and a chronometer which was never accurate and which could never be corrected; so it was seldom used. Their navigation was mostly by guess and by God, but they got places. They could always sail the most direct course toward home because of the marvellous homing sense which is common to all Pellucidarians, a Providential compensation for their lack of guiding celestial bodies.

Kander is king of Amoz. The title, like that of Emperor, was Perry's idea. Kander, like the other kings of the confederation, is chief of a tribe of cave men. He is about as far advanced in the scale of evolution and civilization as the Cro-Magnons of the outer crust were in their time; but like the Cro-Magnons, he is intelligent.
