The anchorage, which I named English Road, (being the first who anchored there), is on the N. W. side, in latitude 21° 20ʹ 30ʺ south. The bearing we took when at anchor, already mentioned, together with the chart, will be more than sufficient to find this anchorage. The bank is a coarse sand; it extends two miles from the land, and on it there is from twenty to forty fathoms water. The small creek before it affords convenient landing for boats at all times of the tide; which here, as well as at the other islands, rises about four or five feet, and is high water on the full and change days about seven o’clock. The island of Tongatabu is shaped something like an isosceles triangle, the longest sides whereof are seven leagues each, and the shortest four. It lies nearly in the direction of E. S. E. and W. N. W. is nearly all of an equal height, rather low, not exceeding sixty or eighty feet above the level of the sea. This island, and also that of Eaoowe, is guarded from the sea by a reef of coral rocks extending out from the shore one hundred fathoms more or less. On this reef the force of the sea is spent before it reaches the land or shore. Indeed, this is, in some measure, the situation of all the Tropical Isles in this sea that I have seen; and thus nature has effectually secured them from the encroachments of the sea, though many of them are mere points when compared to this vast ocean. Van Diemen’s Road, where we anchored, is under the north-west part of the island, between the most northern and western points. There lies a reef of rocks without it, bearing N. W. by W. over which the sea breaks continually. The bank does not extend more than three cables lengths from the shore; without that, is an unfathomable depth. The loss of an anchor, and the damage our cables sustained, are sufficient proofs that the bottom is none of the best.
