On the east side of the north point of the island, (as Mr Gilbert, whom I sent to survey the parts, informed me) is a very snug harbour, of one mile or more in extent, wherein is seven, eight, and ten fathoms water, with a clean sandy bottom. The channel, by which he went in and out, lies close to the point, and has only three fathoms water; but he believes, that farther to the N.E. is a channel with a much greater depth, which he had not time to examine. Indeed, it would have taken up far more time than I could spare to have surveyed these parts minutely; as there lies a number of small islets and reefs of rocks along the N.E. side of the island, which seemed to extend to the N.E. farther than the eye could reach. The island of Amsterdam, or Tongatabu, is wholly laid out in plantations, in which are planted some of the richest productions of nature, such as bread-fruit, cocoa-nut trees, plantains, bananoes, shaddocks, yams, and some other roots, sugar-cane, and a fruit like a nectarine, called by them _Fighegea_, and at Otaheite _Ahuya_: In short, here are most of the articles which the Society Islands produce, besides some which they have not. Mr Forster tells me, that he not only found the same plants here that are at Otaheite and the neighbouring isles, but several others which are not to be met with there. And I probably have added to their stock of vegetables, by leaving with them an assortment of garden seeds, pulse, &c. Bread-fruit here, as well as at all the other isles, was not in season; nor was this the time for roots and shaddocks. We got the latter only at Middleburg.
