Log entries covering the voyage between Plymouth and Madeira. The entries are mostly daily, with some summarised. On 2 July Wales notes that [Admiral Sir Hugh] Palliser and some other gentlemen came on board and were saluted with ‘three cheers’ by the seamen. Before the ship set sail, Wales and Bayly took observations on shore at Drake’s Island. On 10 July he carried the timekeepers ashore to set the time, noting that Mr [John] Arnold set his timekeeper himself; the timekeepers were then checked by Captain Cook and Lieutenant Cooper before being carried on board. In the entry for 12 July, Wales provides details of his equipment, which included compasses made by Mr Gregory and Mr Adams, and a map of Plymouth by Mr Gilbert. The ship set sail from Plymouth on 13 July with the Adventure in company. The following entries record information on the ship’s course, latitude and longitude readings, variations, barometer and thermometer readings, and other observations by Wales. On 20 July they sighted the coast of Spain, landing at Madeira on 29 July, where Wales records that he was obliged to take his instruments ashore to the Custom House, ‘where every box was opened and examined, which took up much time’.
Note that the entries for 13-31 July continue over two pages for each day.
