to fourteen inches in diameter, and the bag, made of 

 double bobbinet and attached to the wire by strong linen 

 or cotton, should taper regularly, have a rounded bot- 

 tom, and be about thirty inches long, so as to double 

 over the net and have a few inches to spare. By 

 bending the two ends of the wire, as in Pig. 197, 

 they can be dropped into a brass tube 

 and securely fixed in place by a tight 

 plug of hard wood, leaving the other 

 end of the tube open for the insertion 

 of a removable handle ; or a very con- 

 venient form of net can be construct- 

 ed on the following plan shown in 

 Fig. 198, and thus described by Mr. 

 Riley : " Take two pieces of stout wire, 

 each about twenty inches long ; bend 

 them half circularly and join at one end 

 by a folding hinge having a check on 

 one side (Z). The other ends are bent 

 and beaten into two square sockets (/), 

 which fit to a nut sunk and soldered into 

 one end of a brass tube (d). When so 

 fitted they are secured by a large-headed t net ha ~ ndl < 

 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 con- 

 venient carriage ; and the handle may be made of any 

 desired length by cutting a stick and fitting it into the 

 hollow tube , which should be about six inches long." 

 The stick should be about four feet long. Mr. Lintner 

 makes use of a rod with a head [Fig. 199] screwed to 

 one end, in which to fasten an elastic brass ribbon, on 

 which the net is drawn, but which when not in use 

 may be placed inside the hat, while the stick serves as 

 a cane, and the head and bag may be placed in the 

 pocket. An entomologist becomes a less conspicuous 

 personage with such an outfit. 



The " chase" for butterflies should rarely be a ques-
