[EAST COAST. PORT JACKSON] 1803 The third volume of my log book and journal having been lost in the events which succeeded the decay of the Investigator, I have had recourse to a memorandum book and to officers journals to supply the dates and leading facts contained in the first three chapters following; fortunately, my bearings and the astronomical observations taken by lieutenant Flinders and myself were preserved, as also were the rough charts, with one exception; so that there are few cases where this department of the voyage will have materially suffered. There are, however, many circumstances related in these chapters, which either do not enter at all, or are slightly mentioned in the officers journals; for these, my public papers and copies of letters have principally furnished materials, and a tolerably faithful memory has supplied the rest. It seemed necessary to explain this, that the reader may know to what the deficiencies and abridgments in some parts of these chapters are to be attributed; and this being premised, I resume the narrative of our preparations for returning to England. 20 JULY 1803 On July 20, lieutenant Fowler quitted the Investigator, with the crew selected for him, and took the command of His Majesty's armed vessel _Porpoise_; and on the following day I went on board with the rest of my officers and people, to go with him as passengers. Amongst other preparations for the voyage, a green house was set up on the quarter deck of that ship; and the plants collected in the Investigator from the south, the east, and north coasts of Terra Australis were deposited in it, to be conveyed to His Majesty's botanical garden at Kew; and as we had had the misfortune to lose the gardener of the expedition, and Mr. Brown, the naturalist, remained behind, a man from Port Jackson was engaged to take care of the plants during the passage. The examination of Torres' Strait was one of the most important articles of my instructions which had been executed only in part; and although I could not pretend to make any regular survey in the Porpoise, it was yet desirable to pass again through the strait, and lay down as many more of its dangers as circumstances would admit; and this being represented to governor King, the following paragraph was made an article in lieutenant Fowler's orders.
