(M74) If the reader should entertain any doubt on the subject, and should suspect that in arriving at this conclusion the Dutch traveller gave the reins to his fancy rather than followed the real opinion of the people, these doubts and suspicions will probably be dispelled by comparing the similar games which another primitive agricultural people avowedly play for the purpose of ensuring good crops. The people in question are the Kai of German New Guinea, who inhabit the rugged, densely wooded mountains inland from Finsch Harbour. They subsist mainly on the produce of the taro and yams which they cultivate in their fields, though the more inland people also make much use of sweet potatoes. All their crops are root crops. No patch of ground is cultivated for more than a year at a time. As soon as it has yielded a crop, it is deserted for another and is quickly overgrown with rank weeds, bamboos, and bushes. In six or eight years, when the undergrowth has died out under the shadow of the taller trees which have shot up, the land may again be cleared and brought under cultivation. Thus the area of cultivation shifts from year to year; and the villages are not much more permanent; for in the damp tropical climate the wooden houses soon rot and fall into ruins, and when this happens the site of the village is changed.(324) To procure good crops of the taro and yams, on which they depend for their subsistence, the Kai resort to many superstitious practices. For example, in order to make the yams strike deep roots, they touch the shoots with the bone of a wild animal that has been killed in the recesses of a cave, imagining that just as the creature penetrated deep into the earth, so the shoots that have been touched with its bone will descend deep into the ground. And in order that the taro may bear large and heavy fruit, they place the shoots, before planting them, on a large and heavy block of stone, believing that the stone will communicate its valuable properties of size and weight to the future fruit. Moreover, great use is made of spells and incantations to promote the growth of the crops, and all persons who utter such magical formulas for this purpose have to abstain from eating certain foods until the plants have sprouted and give promise of a good crop. For example, they may not eat young bamboo shoots, which are a favourite article of diet with the people. The reason is that the young shoots are covered with fine prickles, which cause itching and irritation of the skin; from which the Kai infer that if an enchanter of field fruits were to eat bamboo shoots, the contagion of their prickles would be conveyed through him to the fruits and would manifest itself in a pungent disagreeable flavour. For a similar reason no charmer of the crops who knows his business would dream of eating crabs, because he is well aware that if he were to do so the leaves and stalks of the plants would be dashed in pieces by a pelting
