Mr. J. S. Johnson, in the Naturalist's 

 Journal, describes an instrument useful lor 

 I capturing moths, etc., that have once been 

 disturbed, or are in obscure places, under 

 bark, small twigs, etc. He says : '■^The gig 

 is made from a metallic pen-holder ; to prc- 

 ( pare one, cut off the part where the pen is 

 I inserted, and force in a piece of wood, to 

 ! which is fastened three needles set in a tri- 

 ! angle, projecting from the holder half an 

 ; inch or so. When not in use it can be car- 

 ried in the pocket like a pen-holder ; by 

 simply reversing the plug, the holder forms 

 a sheath for the needles.
