Off the island to thewest, at a distance of 2 to 4 miles, lie three smaller islands, Uea,Hatana, and Hoflewa, in a line from north-east to south-west. The Eastern End. f.

[Feb. 1898, about 5 miles long by 2g broad, and the heights of its hills Yary up to860 feet. Along it the hills run in two lines, but to the east theyare closed by Satarua, so that they appear to have a U-shape witha deep and, in places, very broad valley between, right up thecentre. Eound this, everywhere between the hills is a ridge with ageneral height of a little over 100 feet, and a minimum of about60 feet between Satarua and Hof. On their outer faces, towardsthe sea, are extensive beach-sand deposits, especially to the north atOinafa and to the south at ISToatau and Pepji, while the flat landbetween the two ends is similarly formed. On the reef, which isfringing, with in places an approach to the barrier class, are severalislets with a gradual slope towards the land, but precipitous cliffs tothe sea. On an examina
