[Sidenote: Different names of this island.] This island is called Loo-choo, and sometimes Doo-choo, by the natives. In our maps it is variously written, but mostly Lekayo: the Chinese know it by the name of Low-kow. The spelling used by Mr. Horsburgh in his directions, Lieou-kieou, or Lieu-chew. [Sidenote: Geographical limits and general aspect.] The island lies between 26º 4-3/4' and 26º 52-1/2', north, and between 127º 34' and 128º 18' east, being very nearly sixty miles long in a north-east direction, and preserving a tolerably uniform breadth of about ten or twelve miles. The north end is high and bold, with wood on the top of the hills. The north-east coast is also abrupt, but quite barren. The south-east side is low, with very little appearance of cultivation. The south, south-west, and western faces, particularly the two former, are of moderate height, and present a scene of great fertility and high cultivation: it is to this quarter that the mass of population have resorted. The north-west side is generally rugged and bare. [Sidenote: Deep bay.] [Sidenote: Barrow's Bay.] There are two deep indentures, one on each side of the island; that on the west has at least one hundred fathoms depth, and appears to have no coral in it: while the eastern bight is extremely shallow, and is not only skirted by a broad fringe of coral, but has reefs in the centre; and these last are very dangerous, for they give no warning either by breakers or discoloration of the water, or by soundings: and this remark will apply generally to all the reefs round this island, rendering the navigation, particularly at night, very dangerous. [Sidenote: General caution respecting coral reefs.] [Sidenote: Sugar Loaf or Eegooshcoond.] The most remarkable headland is the island called by Captain Broughton the Sugar Loaf, and by the natives Eegooshcoond (tower or castle); it can be seen distinctly at the distance of twenty-five miles when the eye is elevated only fifteen feet. It is a high conical mountain, varying very little in its aspect when viewed from different quarters: as there is no other peak like it on or near this island, it cannot be mistaken. The latitude of the peak is 26º 43' north; and I have reason to believe that this is within one mile of the truth. Its longitude is 127º 44', or 6' east of the observatory at Napakiang, by two chronometers. The base of the cone and one-third of the way up is covered with houses; and the whole island has the appearance of a garden. When nearly on the meridian of the Sugar Loaf its top seems rounded off.
