Cook sailed completely round the North Island, charting the shores with great care, often landing, sometimes finding tribes who made friends, more often finding tribes whose insolence or treachery led to the necessity of firing upon them with small shot. If he had only known the customs of these people he would have understood that to be friendly with one tribe meant that the next tribe would murder and eat them for revenge. He then sailed round the South Island, landing less frequently, however, till at length he took his leave of New Zealand at what he called Cape Farewell, and sailed away to Australia. He had been nearly six months exploring the coasts of these islands, and that in a very small vessel. During this time he had left pigs and goats, fowls and geese to increase in the forests, where they soon multiplied, especially the pigs. Potatoes and turnips were left with many tribes, who quickly learnt how to grow them, so that after ten or twelve years had passed away these vegetables became the chief food of all the Maoris. #5. French Visitors.#--Whilst Cook was sailing round the North Island, a French vessel anchored in a bay of that island in search of fresh water. The Ngapuhi tribe received them with pleasure and gave them all the assistance in their power, but some of them stole a boat. The captain, named De Surville, then seized one of the chiefs and put him in irons. The boat not being given up, he burnt a village and sailed to South America, the chief dying on the road.
