Is covered by the four main islands, Ponape and Kusaie in the eastern group, Truk or Hogolu in the central, and Yap in the western.
These islands are of considerable elevation (the highest point of Ponape approaches 3000 ft.), but the rest are generally low coral islets.
The Germans divide the whole archipelago into two administrative districts, eastern and western, having the seats of government at Ponape and Yap respectively.
In Ponape and Kusaie, massive stone structures, similar to those which occur in several other parts of the Pacific Ocean, have long been known to exist.

There is communication with Sydney by private steamer, and a steamer sails between Jaluit and Ponape to connect with the French boats for Singapore.
