It was in the Bay of Tolaga, the right name of which is Houa-Houa, that D'Urville found the first opportunity of gaining some information about the "kiwi," by means of a mat decorated with the feathers of that bird, such mats being articles of luxury among these islanders. The "kiwi" is about the size of a small turkey, and, like the ostrich, has not the power of flying. It is hunted at night by the light of torches and with the assistance of dogs. It is this bird which is also known under the name of the "apteryx." What the natives told D'Urville about it was in the main accurate. The apteryx, with the tail of a fowl and a plumage of a reddish-brown, has an affinity to the ostrich; it inhabits damp and gloomy woods, and never comes out even in search of food except in the evening. The incessant hunting of the natives has considerably diminished the numbers of this curious species, and it is now very rare. D'Urville made no pause in the hydrographical survey of the northern island of New Zealand, keeping up daily communication with the natives, who brought him supplies of pigs and potatoes. According to their own statements, the tribes were perpetually at war with one another, and this was the true cause of the decrease in the population of these islands. Their constant demand was for fire-arms; failing to obtain these, they were satisfied if they could get powder in exchange for their own commodities. On the 10th February, when not far from Cape Runaway, the corvette was caught in a violent storm, which lasted for thirty-six hours, and she was more than once on the point of foundering. After this, she made her way into the Bay of Plenty, at the bottom of which rises Mount Edgecumbe; then keeping along the coast, the islands of Haute and Major were sighted; but during this exploration of the bay, the weather was so severe that the chart of it then laid down cannot be considered very trustworthy. After leaving this bay, the corvette reached the Bay of Mercury; surveyed Barrier Island, entered Shouraki or Hauraki Bay, identified the Hen and Chickens and the Poor Knights Islands, finally arriving at the Bay of Islands. The native tribes met with by D'Urville in this part of the island were busy with an expedition against those of Shouraki and Waikato Bays. For the purpose of exploring the former bay, which had been imperfectly surveyed by Cook, D'Urville sailed back to it, and discovered that that part of New Zealand is indented with a number of harbours and gulfs of great depth, each one being safer, if possible, than the other. Having been informed that by following the direction of the Wai Magoia, a place would be reached distant only a very short journey from the large port of Manukau, he despatched some of his officers by that route, and they verified the correctness of the information he had received. This discovery, observes Dumont d'Urville, may become of great value to future settlements of Shouraki Bay; and
