of them are mere points when compared
to this vast ocean. Van Diemen's Road, where we anchored, is under the
northwest 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
length 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.

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.[3]

The produce and cultivation of this isle is the same as at Amsterdam; with
this difference, that a part only of the former is cultivated, whereas the
whole of the latter is. The lanes or roads necessary for travelling, are
laid out in so judicious a manner, as to open a free and easy communication
from one part of the island to the ot
