After stopping at Pulo Sabuda Dampier rounded the north-western promontory of New Guinea, calling at some of the small islands for wood and water and shellfish, some of which were "cockles" weighing 10 pounds each, and other huge bivalves, clams, weighing 78 pounds. At most of these islands they saw the same large fruit-bats. One of these islands off Waigiu (in what is still called the Dampier Strait) he named after King William III. After that he continued to sail round the north coast of New Guinea, past islands which he knew to have been previously discovered by the Dutch. At last he reached the vicinity of the two great islands now known as New Mecklenburg and New Pomerania. He took them to be one island, to which he gave the name of Nova Britannia (New Britain), a name which it bore down to the days of Captain Cook, who christened the northern portion, which was found to be a separate island, New Ireland. Dampier, landing on the northern coast of New Ireland (now New Mecklenburg), described it as high and mountainous, adorned with tall, flourishing trees, possessing many plantations and patches of cleared land. The natives, however, flung stones at them with their slings, so Dampier renounced any attempt to obtain water there. For this purpose he called at Gerrit Denys Island, one of an archipelago lying to the north of New Ireland, and here the natives were more friendly. The island was thickly populated, the people being very black, strong, and stout-limbed. Their hair was short and curly; besides being clipped into different patterns, it was dyed or bleached a variety of colours, red, white, or yellow, besides its original black. These people had broad, round faces, with big, bottle noses, yet looked agreeable enough until they disfigured themselves by tatuing[64] and by wearing things through the septum of the nostrils as big as a man's thumb and 4 inches long. Sometimes these objects were passed actually through the cheeks, and not through the nostrils. They also made holes in their ears into which they thrust pieces of bone or wood. They were very dexterous with their canoes, which were fitted with outriggers on one side. The bow and the stern rose high and were carved into extraordinary painted devices resembling birds, fish, or a man's hand. Dampier, noticing these people had no knowledge of metal utensils, and knowing nothing of their stone weapons, wondered how they could carve this work so elaborately. Their speech was clear and distinct, and for a sign of friendship they would hold up the bow of a tree full of leaves. Continuing his circumnavigation of "Nova Britannia", Dampier discovered and named the entrance to St. George's Channel, but he believed it to be only a deep indentation, and did not realize it was a passage between New Ireland and New Britain. Calling at Port Montague, off the south coast of New Britain, where the land was mountainous, woody, full of rich valleys and pleasant water
