Figure 140.—Atiu eel trap (Bishop Mus., C2850). a, mesial section of trap: total length, 495 mm.; greatest diameter, 255 mm.; diameter at small end, 101 mm.; length of funnel, 310 mm.; funnel at opening about 65 mm. (2.5 inches) in diameter, extends as an even cylinder (1) for about 158 mm.; increases in diameter (2) by addition of four more warps for about 72 mm., and still more (3) by addition of eight more warps for about 82 mm. which brings it to outer circumference (4); warps are bent over to form body (5) and later diminish in size to reach rim opening (6) at small end. b, commencement of funnel end opening with warps flattened out to show twining technique; six warps (1-6) are used but in order to prevent slipping over ends of individual warps, they are arranged in three pairs formed by doubling three pieces of vine so that bends will form free edge of funnel; weft elements also are locked by doubling one piece of vine (7) around first warp (1) and then its two elements around second part (2) of pair in a twine which is continued around other warps as shown; twine reaches first warp (1) and continues a second row close to previous one; continuous twine is continued over the six warps until first even part of cylinder (a, 1) is completed. c, diagram of open end of trap, showing addition of warps forming three areas eccentric to funnel hole in center: inner area (1) has six warps forming even cylinder (a, 1); intermediate area (2) adds four more warps to make a total of 10 in expanding part corresponding to a, 2; outer area (3) adds eight more warps to total 18 in area corresponding to a, 3; this brings expanding opening up to outer margin of large end (a, 4), but another one (4) is added to make a full complement of 19 which are turned back to make outer wall (a, 5); throughout, single-pair twine is carried out in a continuous encircling movement. d, addition of new warps: old warps (1-3) are shown covered at lower end by three rows (6) of twining; additional rods (4, 5) have been pushed down beside two old rods (1, 2) between pairs of three rows of twining; they were then diverged, and next weft row (7) took turns around each of the five warps as did the succeeding rows above them; after the first couple of rows, warps were kept parallel and the twining became even. e, addition of new weft elements: one element of a weft pair was always cut off shorter than the other so that additions could be made singly; in upper row formed by weft pair (5, 6) one of pairs (5) has passed around warps 1 and 2 but is too short to go past warp 3; a new weft strip (7) is pushed down beside warp 2 between pairs of three rows, old weft 5 is dropped on near side of warp 3, and new weft 7 takes its place to pass in front of warp 3 and behind next warp (4) to continue twining while other original member of pair (6) continues until so short it is replaced; the continuous weft twine is rendered possible by such replacements. f, rim finish: when body of trap is diminished gradually in size toward small end, seven of full quota of 19 warps are inclined toward neighboring warps that will maintain even spacing, and two such warps just before and after meeting are included under same turn of twine, and after being so fixed by a number of rows, one of each pair is dropped or cut off; 12 warps at small end; when second last row (1) of twining is being made as always from left to right, warp head (4) is bent over in a curve, laid on near warp (3), and included under turn of twine (1); similarly, next warp (5) is bent over on near warp (4) and caught under turn of twine of second last row (1); when circuit is completed, last weft row (2) merely repeats including bent over warp ends with warps on which they rest; on completing second and final circuit, weft ends are cut off after passing through arch made by last warp; two of 12 warps were cut off above last twined row without being bent over.
