Notwithstanding the prohibition against Forster, a book was published under his son's name, and the latter claims that he started on the voyage with the intention of writing, took copious notes, and, excepting that he utilised those taken by his father, the work was entirely his own. He forgets, however, to say that a quantity of Cook's manuscripts had been in his father's hands, and does not explain how so much of his book corresponds with curious exactitude with that of Cook (in many cases word for word), and how, when the papers of Cook failed to provide him with further facts, he was obliged to rely on would-be philosophical dissertations which it is to be hoped were not obtained from his father's notebooks. Young Forster says that the appointment was first of all given to his father in a spirit of pique on the part of Lord Sandwich, and then the order forbidding him to write was made because the father had refused to give Miss Ray, Lord Sandwich's mistress, who had admired them when on board the ship, some birds brought home from the Cape of Good Hope as a present to the Queen. In the end the Forsters forestalled Cook's book by about six weeks, and as this was after Cook had left England on his last voyage, Mr. Wales undertook the defence of the absent against the sneers and insinuations that were plentifully given out all round. The Forsters infer that Cook was unreliable because he suppresses mention of the bombardment of the Loo fort at Madeira, an event which never happened; and because he places Valparaiso (where he had never been) in the position given on the Admiralty chart supplied to him, which proved to be some 10 degrees out. The Master who had refused to give up his cabin was, of course, never forgiven; and as for Mr. Wales, who had observed the Transit of Venus at Hudson's Bay in 1769, for the Royal Society, he, poor man, had neither knowledge nor experience in astronomical science. The crews of the two ships also, carefully selected men though they were, some of whom had been the previous voyage, were morally and physically bad, and utterly incapable of performing their duty in a proper and seamanlike manner. A little allowance must be made for the two authors, for the father suffered severely from rheumatism, the son was of a scorbutic tendency, and both were unaccustomed to sea life, and doubtless the hardships inseparable from such a voyage pressed heavily upon them.
A second Journal was published by F. Newbery about the same time, and Cook hearing of it, sent Anderson, the gunner, to find out the author. With little difficulty he was found to be Marra, the gunner's mate who tried to desert at Otaheite, and the publication was stayed till after the authorised version was out.
A volume of Cook's letters to Dr. Douglas relating to the preparation of his Journal for the press is preserved at the British Museum, and it shows how Cook to the very last endeavoured to serve Mr. Forster's interests, and to smooth matters over so that they could work together. The last one Dr. Douglas received before Cook's departure was dated from Mile End, 23rd June 1776, the day before he joined his ship at the Nore.
Dear Sir,
It is now settled that I am to publish without Mr. Forster, and I have taken my measures accordingly. When Captain Campbell has looked over the manuscript it will be put into the hands of Mr. Strahan and Mr. Stuart to be printed, and I shall hope for the continuation of your assistance in correcting the press. I know not how to recompense you for the trouble you have had and will have in the work. I can only beg you will accept of as many copies after it is published as will serve yourself and friends, and I have given directions for you to be furnished with them. When you have done with the Introduction, please send it to Mr. Strahan or bring it with you when you come to Town, for there needs be no hurry about it. Tomorrow morning I set out to join my ship at the Nore, and with her proceed to Plymouth where my stay will be but short. Permit me to assure you that I shall always have a due sense of the favour you have done me, and that I am with great esteem and regard, Dear Sir, your obliged and very humble servant,
James Cook.
Notwithstanding the Forsters' endeavour to discount its success by forestalling the publication by some weeks, Cook's work was well received by the public, and Mrs. Cook, to whom the whole of the profits were given, reaped considerable benefit from its sale.
