DESCRIPTION. 261 



knowledge it is very successful. The height of this device, 

 which is represented above as " gillrad," or set, is about 

 four feet ; the diameter of the upper part, from three to 

 four feet, and, of the lower, less than two feet. It is in 

 two compartments, a moveable wire-frame separating 

 them ; the lower one, which is twelve to fifteen inches 

 in height, being intended for the reception of the decoy- 

 bird. The framework of the trap consists of slips of 

 wood which though left open in the diagram for the 

 better understanding of the plan of setting it are covered 

 over either with strong netting or wire-work. The stout 

 post on which the trap stands is about four feet in height. 

 B is the so-called giller-kors, consisting of a treble 

 'cross a sort of "hen-ladder," as we, perhaps, should 

 call it one end of which rests in an aperture in the 

 upi'ight C, whilst the other end, after passing through an 

 oblong hole in the opposite upright D, is supported by 

 M the " giller-pinne," or "trigger;" E the net, that 

 covers, when unfolded, the opening in the trap, which is 

 fastened in the middle and at both ends to the cross piece 

 P. To the front of the net is attached a slight metal rod, 

 and to the sides of the net rings, which, when the trap is 

 sprung, traverse on the metal rods G, G, in the manner 

 of a curtain ; L a stout wire, one end of which is fastened 

 to the " giller-pinne " M, and the other to the metal bar in 

 front of the net ; II H, lines attached to the ends of the 

 same metal rod, which after passing through the small 

 apertures I I, in the front cross-piece, unite in K, a 

 somewhat heavy weight, and A the small door by which 

 the decoy-bird, is introduced into the trap. The colour 

 of this, it should be remarked, is regulated by the locality. 

 If the soil thereabouts be of a light colour, a dark plumaged 

 bird is preferable ; but if the contrary be the case, a white 

 one. A Duck, a Hen, or a Pigeon, will answer the 

 purpose equally well.
