" The beauty and straightness of the bore is remarkable." (Mundy ii. 226.) " The boring of a sumpit by a skilful hand is performed in a day. The instrument used is a cold iron rod, one end of which is chisel-pointed and the other round." (Burns, Jour. Ind. Arch. iii. 142.) " The bore of these blow-pipes is as clean and bright as that of a gun-barrel, and is about six feet long, and drilled through a log of hard wood ; the log is then pared down and rounded to less than an inch in diameter." (Whitehead, p. 75.) The most complete account of the boring process is that given by Mr. Crocker, who saw it performed by a Bakatan : " A hard piece of wood had been selected the length required and reduced to the size of a man's wrist, this was fastened to a post forming a part of a raised platform to the house. The operator stood underneath and bored upwards with a long piece of round iron the length of the sumpitan and sharpened at one end like a chisel. Two bits of round wood, about 8 inches long, were fastened by rings of rattans to the iron forming a movable handle. The iron was beautifully round and made out of native iron like the Kayan weapons; the rod or chisel in question had been in the tribe as long as any of them could recollect. The traveller is naturally astonished to find the holes of the blow-pipe so straight, when he sees the simple contrivance employed ; besides a good eye they must be possessed of more than ordinary perseverance, as the method of boring is tedious to a degree. After the hole is bored a piece of rattan is worked through until the desired smoothness is obtained, when the outside is reduced to the usual size and polished by constant rubbing." (S.G., No. 123, p. 6.)
Mr. Witti (Diary, 20 Nov.) says the Dusuns calls the blow-pipe Sopok and not Sumpitan, but Sopok also means a spear.
" The darts are of various sorts." (Dalton, p. 51.) "The arrow is a small splinter of nibong about as thick as a stocking wire, stuck into a small
