When discussing the route with Governor King before leaving Sydney, Flinders had pointed out that the size of the Cumberland, and the small quantity of stores and water she could carry, would oblige him to call at every convenient port; and he mentioned that the places which he contemplated visiting were Kupang in Timor, Ile-de-France (Mauritius), the Cape of Good Hope, St. Helena, and one of the Canaries. But King took exception to a call being made at Ile-de-France, partly because he did not wish to encourage communication between Port Jackson and the French colony, and partly because he understood that hurricane weather prevailed in the neighbourhood at about the time of the year when the Cumberland would be in the Indian Ocean. To respect King's wishes, Flinders on leaving Kupang set a course direct for the Cape of Good Hope. But when twenty-three days out from Timor, on the 4th of December, a heavy south-west ground swell combined with a strong eastern following sea caused the vessel to labour exceedingly, and to ship such quantities of water that the one effective pump had to be kept working day and night continually. If anything went wrong with this pump, a contingency to be feared from its incessant employment, there was a serious risk of foundering. After enduring two days of severe shaking, Flinders came to the determination that considerations of safety compelled him to make for Ile-de-France. On December 6th, therefore, he altered the Cumberland's course for that island. When he wrote his Voyage to Terra Australis, he had not his journal in his possession, and worked from notes of his recollections. In telling the story now, the author has before him not only what Flinders wrote in this way, but also a copy of the French translation of the journal which Decaen had prepared for his own use, and several letters written by Flinders, wherein he related what passed in his mind when he resolved to alter his course. The first and most imperative reason was the necessity for repairing the ship and refitting the pumps. Secondly, rations had had to be shortened, and victuals and water were required. Thirdly, Flinders had come to the conclusion that the Cumberland was unfit to complete the voyage to England, and he hoped to be able to sell her, and procure a passage home in another ship. "I cannot write up my journal unless the weather is extremely fine," he wrote. Fourthly, he desired "to acquire a knowledge of the winds and weather at the island of the actual state of the French colony, of what utility it and its dependencies in Madagascar, might be to Port Jackson, and whether the colony could afford me resources in my future voyages."* (* Journal.)
