In the small prison of Sampit, which is built of iron-wood, the mortality from beri-beri among the inmates was appalling. Nine men, implicated in the murder of two Chinese traders, in the course of eight months while the case was being tried, all died except a Chinaman who was taken to Bandjermasin. I understood a new prison was about to be erected. It seems improbable that ironwood has any connection with this disorder, but Mr. Berger, manager of the nearby rubber plantation, told me the following facts, which may be worth recording: Six of his coolies slept in a room with ironwood floor, and after a while their legs became swollen in the manner which indicates beri-beri. He moved them to another room, gave them katjang idju, the popular vegetable food, and they soon recovered. He then replaced the ironwood floor with other material, and after that nobody who slept in the room was affected in a similar way. I met in Sampit three Dayaks from the upper country of the Katingan on whom the operation of incision had been performed. According to reliable reports this custom extends over a wide area of the inland, from the upper regions of the Kapuas, Kahayan, and Barito Rivers in the east, stretching westward as far as and including the tribes of the Kotawaringin. Also, in the Western Division on the Upper Kapuas and Melawi Rivers, the same usage obtains. In Bandjermasin prominent Mohammedans, one of them a Malay Hadji, told me that the Malays also practise incision instead of circumcision. The Malays, moreover, perform an operation on small girls, which the Dayaks do not. The controleur invited me to take part in a banquet which he gave to celebrate the completion of a road. There were present Malay officials, also Chinamen, and one Japanese. The latter, who arrived at Sampit one and a half years before with forty florins, had since increased his capital to a thousand through the sale of medicines to natives whom he reached by going up the rivers. We were seated at three tables, twenty-eight guests. The natives were given viands in addition to the menu provided, because they must have rice. Their women had helped to cook--no small undertaking for so many in an out-of-the-way place like Sampit. It was an excellent dinner; such tender, well-prepared beef I had not enjoyed for a long time. Claret, apollinaris, and beer were offered, the latter appearing to be the favourite. Women were served in another room after the men had dined.
