noru] TWINE, CORDS, AND BANDS 1G Er 
bundle with similar ends together, and each containing, as far as 
the operator can judge, an equal number of shreds, anywhere from 
about 12 to as many as 24. The proximal end of one bundle (az) 
is just sufficiently rolled into a corresponding length of the distal 
extremity of a second (bz) as to make one very loose strand of 
them—the length of a fiber shred. A similar procedure is carried 
out with the third and fourth (cz, dz). The two resulting strands 
are next placed side by side together, and the thigh rolling com- 
menced at their center—once down and once up. When the twine 
on one side is finished, the whole is turned round, rolling recom- 
menced at the starting point, and the other half completed. The 
finished article (y) is thus the length of one fiber shred.

formed by the rolling together of three bundles of fibers. It is 
made not only for catching that particular fish, but certain others, 
its manufacture varying only in the length employed. Thus, while 
the huri-aring measures at most 2 fathoms, the oradiro-, the warburi-, 
and the lukunanni-aring run up to something like 4, while the 
wirokotori-aring will measure from 20 to.24. So also hammock 
scale lines which are made in an identical manner will reach this 
extreme length and, if necessary, can eventually be manufactured 
into a hammock rope. A bowstring is another article built up on 
the same lines as the huri-armg. As a matter of fact, the method 
of manufacture of the huri-aring demonstrates how increased length 
and uniform thickness can be simultaneously obtained (D): Several 
bundles of kuraua (az, bx, cx, etc.) are arranged so that each will 
contain about an equal number—say, 12—fiber shreds, all arranged, 
of course, with similar ends together. With three bundles (az, 
bx, cx), which are placed one slightly in advance of the other, a 
start is made at about 6 inches from their thinner extremity, where all 
three are rolled into one, once down and once up, and this shorter end 
of the twine completed first. Taken off and reversed on the thigh, 
the longer end is commenced to be rolled at, the starting point, and 
when about halfway to completion, the distal (thin) extremity of a 
fourth bundle (dz) is rolled into the hindmost one (cz) of the original 
three (cd), which are then again all rolled together (1, m). After 
a while the distal (thin) end of a fifth bundle (ex) is rolled into the 
second (bx) of the original three (ber), and all three again rolled 
together (im, Iv). Later, the distal extremity of a sixth bundle is 
similarly joined into the third of the original three, the whole again 
rolled, and so the process is repeated by inserting the thin extremity 
of a new bundle successively into the thick extremity of the hindmost 
bundle exposed. Experience alone seems to teach the operator when 
the varying thickness of the resulting twine renders it opportune to 
insert a new bundle (WER, 11).
