From A Death in the Rainforest: How a Language and a Way of Life Came to an End in Papua New Guinea, by Don Kulick (Algonquin Books, 2019), Kindle pp. 31-33:
Tok Pisin entered Gapun in around 1916. A year or so before the outbreak of the First World War, word spread from the coast that white men were in the area searching for young men to work for them. These white men were German labor recruiters, and the men they recruited were to be shipped off to the copra plantations that the Germans had established along the Rai Coast of eastern New Guinea (at that time, it was German New Guinea) and on various distant islands. Two Gapun men, Ayarpa and Waiki, went to the coast to find those white men. They resisted the protests of their relatives, who believed that the white men wanted to lure them away from the village to kill them. The two men were itching for an adventure. They ignored their relatives, found the recruiters, and left with them.
Ayarpa and Waiki joined the scores of men from various parts of the mainland who were taken to a copra plantation on Kokopo near the German settlement of Rabaul, on the faraway island of Neu-Pommern (“New Pomerania”). They remained on this plantation for at least three years, and they apparently witnessed the Australian occupation of Germany’s New Guinea territories at the outbreak of World War I (at which time “New Pomerania” was imperiously changed to “New Britain”). My language teacher in Gapun, old Raya, recalled Ayarpa—who was Raya’s father—describing how the inglis (that is, the Australians) rounded up the Germans and “put them into big crates. They put them all inside the crates, nailed them shut, and sent them back to their country.”
Sometime after the Australian takeover of German New Guinea in 1914, Ayarpa and Waiki came home. The stories that survive them recount how they arrived triumphantly in the village, carrying with them the fruits of their labor. Each man had a small wooden patrol box filled with “cargo”: steel knives, machetes, axes, bolts of factory-made cloth, European tobacco, saucer-sized ceramic plates that looked like seashells. (Villagers throughout New Guinea regarded such flat seashells as valuable items, and knowing that, the Germans mass-produced counterfeit ones in white ceramic to pay their laborers.) But just as impressive and even longer lasting than the goods they brought with them were the stories they told about working on the plantation. And most impressive of all was the new language the men had acquired while working for the white men.
As most people in New Guinea did at the time, Ayarpa and Waiki assumed that Tok Pisin was the language of white men. And like the steel axes and fake seashells that entered the village’s redistributive networks, so did the white men’s language: Ayarpa and Waiki immediately set about sharing the language with their peers.
A few years after Ayarpa and Waiki returned to Gapun, a group of Australian labor recruiters suddenly appeared in the village. This was the first time any white person had actually come to the village, and panic ensued. Most of the terrified villagers fled into the rainforest. Only Ayarpa, Waiki, and a few old people who were too frail to run fast enough to escape were left. Seeing the village thus deserted, the Australians resorted to what was presumably a time-tested technique of persuasion: they gathered together the old people who remained and prevented them from leaving, and then they waited until their anxious cries brought back a few young men. At that point, Ayarpa and Waiki did the recruiters’ work for them: they told the men that if they went off with the white men, they would go to where the two of them had gone, and they would learn Tok Pisin. “We’ve taught you some of the white man’s language,” they are said to have told the men, “but you don’t know it well. If you go away to the plantation, you’ll learn it well.”
Five men left with the recruiters.
And so a pattern of learning Tok Pisin became established. Young men acquired a basic knowledge of the language in the village. They then went off to work as contracted laborers to learn Tok Pisin “well.” Later, when they returned to the village, they taught the language to the young men.
