nia on the south, and New Guinea to the
north; the dimensions of New Zealand; New Caledonia and the New Hebrides,
with the exception of the fact that the northern island of the latter
existed; the Fiji Islands; Sandwich Islands; the Phoenix, Union, Ellice,
Gilbert, and Marshall Groups, with innumerable small islands scattered
here and there; the Cook Islands, and all the Society Islands except
Tahiti. The majority of the Paumotu Group. The coast of North America
north of 45 degrees north was unknown, and there was the great,
undefined, and imaginary southern Continent to disprove.
Whether other voyages of exploration would have been undertaken one
cannot say; but in 1768 the Royal Society put in a word.
A transit of Venus over the sun's disc was to occur in 1769, and
astronomers were anxious to take advantage of it, the object of the
observation being to ascertain the distance of the earth from the sun,
the fundamental base line in all astronomical measurements, and which was
very imperfectly known.
The Central Pacific afforded a favourable position, and the Royal Society
memorialised the king to send a ship for the purpose. The request was
granted, and at first Alexander Dalrymple, who had conducted marine
surveys in the East Indies, and was known as a scientific geographer, was
selected as observer. As, however, it was found that he also expected to
command the ship, the Admiralty positively refused to have anything to do
with him, and after some discussion James Cook was selected.
This says volumes for Cook's reputation at the time. To have risen
absolutely from the ranks was a great deal, but to be chosen as a master,
to command a ship, and undertake a scientific observation of this
importance, was a most exceptional occurrence, and speaks well for the
judgment of those who had the selection.
It seems that Mr. Stephens, the Secretary to the Admiralty, had much to
do with it. How Stephens had become acquainted with Cook history does not
relate, but doubtless his personal visits to the Admiralty in connection
with the completion of his charts of Newfoundland, from which he returned
every winter, had brought him into contact with the Secretary, who had
clearly formed a high opinion of him.
Cook, we may be sure, jumped at the chance, and his pride must have been
great when he found he was to receive a commission as Lieutenant.
This in itself was a most unusual step. The occasions on which a master
