My own experience has led me to the conviction that it is very difficult to draw any safe conclusion from the vocabularies generally collected, because the best are usually made through the medium of the Malay, and the worst by merely showing articles and guessing that the response is the name of the thing shown. I made a list of Bisaya words on the Limbang, another among the Idaán at the foot of “Kina Balu.” I was certain of a great affinity between the languages, as men from one tribe could freely converse with those of the other, though their dwellings were a hundred and fifty miles apart; but on comparing the written vocabularies, I found a surprising difference. Just before I left Borneo, I spoke to a Bisaya on the subject: he said, “Repeat me a few words of the Idaán that are different.” I did so. He answered, “I understand those words, but we don’t often use them,” and he instantly gave their meaning in Malay, to show that he did understand them. My sudden and unexpected return to this country prevented my pursuing the investigation. I mention this circumstance to show that differences are often more apparent than real. Mr. Chalmers’s vocabularies are trustworthy, as he can speak the Land Dayak freely. _Deer._--The Dayaks of the Quop district do not refuse to eat deer. The custom of doing so, however, obtains in Western Sarawak, but chiefly in the Singgi tribe, and then only among the young men. As will be found mentioned in my account of Samarahan, they do so because deer’s flesh produces in those who eat it faint hearts; and as I have elsewhere observed, the interdict on certain kinds of food to the young people is merely selfishness on the part of the elders to secure to themselves a greater share of articles that are not plentiful. The Silakau and Lara Dayaks who have emigrated from Sambas into Lundu, do not eat the flesh of the deer, from an opinion that they descended from Dayak ancestors, but Mr. Chalmers, in his experience of the Sarawak Land Dayak, never heard of any prejudice existing against killing or even eating any animals except the faint-heartedness supposed to be produced by venison; nor did he notice that the serpent had any sacred character. Many people eat it; some, however, refuse, considering it foul-feeding.
