Cook's Journal (III)

The three copies are, practically, identical, except for the period August 13th to 19th, 1770, during which the wording is often different, though the events are the same.  It is not very difficult to account for this.  The two first-mentioned Journals are in the handwriting of an amanuensis, Mr. Orton, the clerk. No autograph journal is, so far as is known, in existence, but some rough original must have been kept, as both copies bear internal evidence of having been written up after the lapse of an interval after the events described.

This is markedly the case in the Australian part of the Journal.  It is known that Botany Bay was at first called by Cook, Stingray Bay, on account of the number of rays caught there; but after Banks had examined his collection, and found all his plants new to science, Cook determined to call it Botany Bay. It is, however, called Botany Bay from the first in the Journals.

The name, "New South Wales," was not bestowed without much consideration, and apparently at one stage New Wales was the appellation fixed upon, for in Mr. Corner's copy it is so called throughout, whereas the Admiralty copy has "New South Wales."

It would therefore seem that about the period of the discrepant accounts Mr. Corner's copy was first made, and that Cook, in the Admiralty copy, which for this part is fuller, revised the wording of his description of this very critical portion of the voyage.

The Queen's Copy has been written with especial care, and by several different hands. It was evidently the last in point of time.  (Wharton 1893)
