r voyage profitable to themselves; but could have little
prospect, if they had been desirous, of making it useful to the public,
by gaining any accession of new land to the map of the world.

By the natural operation of these causes, it could not but happen, that
little progress should be made toward obtaining a full and accurate
knowledge of the South Pacific Ocean. Something, however, had been
attempted by the industrious, and once enterprising, Dutch, to whom we
are indebted for three voyages, undertaken for the purposes of
discovery; and whose researches, in the southern latitudes of this
ocean, are much better ascertained than are those of the earlier Spanish
navigators above mentioned.

Le Maire and Schouten, in 1616, and Roggewein, in 1722, wisely judging
that nothing new could be gained by adhering to the usual passage on the
north side of the Line, traversed this ocean from Cape Horn to the East
Indies, crossing the south tropic, a space which had been so seldom, and
so ineffectually, visited; though popular belief, fortified by
philosophical speculation, expected there to reap the richest harvest of
discovery.

Tasman, in 1642, in his extensive circuit from Batavia, through the
South Indian Ocean, entered the South Pacific, at its greatest distance
from the American side, where it never had been examined before. And his
range, continued from a high southern latitude, northward to New Guinea,
and the islands to the east of it near the equator, produced
intermediate discoveries, that have rendered his voyage memorable in the
annals of navigation.

But still, upon the whole, what was effected in these three expeditions,
served only to shew how large a field was reserved for future and more
persevering examination. Their results had, indeed, enabled geographers
to diversify the vacant uniformity of former charts of this ocean by the
insertion of some new islands. But the number, and the extent of these
insertions, were so inconsiderable, that they may be said to appear

Rari, nantes in gurgite vasto.

And, if the discoveries were few, those few were made very imperfectly.
Some coasts were approached, but not landed upon; and passed without
waiting to examine their extent and connection with those that might
exist at no great distance. If others were landed upon, the visits were,
in general, so transient, that it was scarcely possible to build upon a
foundation so weakly laid, any information that coul
