In the Bismarck Archijielago a num- ber of stems of the prickly ]iahn {Calamus or Daemonorops) are hunched together at one end and allowed to o])en out at the other, forming what will ultimately be, when interlaced, a conical-shaped basket. Vine or cane lashing is used and gives the trap rigidity. The palm stems are so ar- ranged that the hook-like thorns point inwards. A piece of string is attached to the trap, a slab of drift-wood tied at the other end, and a bait placed well inside the basket. To set the trap the native sinks it and places a stone on the string, allowing the float to rise on the surface. The fish readily enters the trap, but on trying to back out or turn, it l)ecomes im])aled on the thorns. The trap from British New Guinea is of more solid construction, but the shape and idea is the same. The barbed stems are lashed to cane ribs, and a crossed stick prevents its being rolled over or otherwise displaced The frame of the Burmese device is made of bamboo. A stem of about twenty inches, butting on a node or knot, is split longitudinally into seven or eight strips. These rib like divisions are interlaced with rattan, as in the forms already described. Stems of the prickly palm are lashed in position inside the cane, and, baited as before, it is plac€'d in the river with the inouth down-stream, and anchored in place by means of an attached stone. Its posi- tion is indicated by a bamboo pole inserted in the river bank, this pole being connected to the trap by a length of rattan. The Yellow Monday Cicada, By Anthony Musgrave.
