 screw (e) threaded to fit into the nut-socket, and with a groove 

 wide enough to receive the back of a common pocket knife 

 blade. The wire hoop is easily detached and folded, as at c, 

 for convenient carriage ; and the handle may be made of any 

 desired length by cutting a stick and fitting it into the hollow 

 tube a, which should be about six inches long. It is well to 

 have two separate hoops — one of lighter wire furnished with

 stronger material for sweeping non-flying specimens. 



" Another still more simple, but less convenient, frame is

" 'Make a loop of strong iron or brass wire, of about 3-lGths 

 of an inch in thickness, so that the diameter of the loop or 

 circle will not exceed twelve inches, leaving an inch to an inch 

 and a half of wire at each end bent at nearly right angles. 

 Bind the two extremities of the wire together with smaller 

 wire and tin them by applying a drop of muriate of zinc, then 

 holding it in the fire or over a gas flame until nearty red hot, 

 when a few grains of block tin or soft solder placed upon
