Their astronomical instruments were of the best, including a portable observatory constructed for sixteen guineas. But most important of all was the careful assortment of provisions, to allay, if possible, that scourge of all navigators, the scurvy. A quantity of malt was shipped to be made into wort, mustard, vinegar, wheat, orange and lemon juice and portable soup was put on board, and Cook received special orders to keep his men with plenty of fresh food whenever this was possible. He carried out these orders strenuously, and at Madeira we find him punishing one of his own seamen with twelve lashes for refusing to eat fresh beef. Hence they left Rio de Janeiro "in as good a condition for prosecuting the voyage as on the day they left England." [Illustration: THE ISLAND OF OTAHEITE, OR ST. GEORGE. From a painting by William Hodges, who accompanied Captain Cook.] Christmas Day was passed near the mouth of the river Plate, and, early in the New Year of 1769, the _Endeavour_ sailed through the Strait of Le Maire. The wealthy Mr. Banks landed on Staaten Island and hastily added a hundred new plants to his collection. Then they sailed on to St. George's Island. It had been visited by Captain Wallis in the _Dolphin_ the previous year; indeed, some of Cook's sailors had served on board the _Dolphin_ and knew the native chiefs of the island. All was friendly, tents were soon pitched, a fort built with mounted guns at either side, the precious instruments landed, and on 3rd June, with a cloudless sky and in intolerable heat, they observed the whole passage of the planet Venus over the sun's disk. After a stay of three months they left the island, taking Tupia, a native, with them. Among other accomplishments this Tupia roasted dogs to perfection, and Cook declares that dogs' flesh is "next only to English lamb." They visited other islands in the group--now known as the Society Islands and belonging to France--and took possession of all in the name of His Britannic Majesty, George III. All through the month of September they sailed south, till on 7th October land was sighted. It proved to be the North Island of New Zealand, never before approached by Europeans from the east. It was one hundred and twenty-seven years since Tasman had discovered the west coast and called it Staaten Land, but no European had ever set foot on its soil. Indeed, it was still held to be part of the Terra Australis Incognita.
