Fig. 41 — Plan of "ring" net.
Fig. 41 shows a strong and easily made net. To make this, procure some brass wire, gauge No. 8 or 9. Cut from the ring of wire sufficient to form a net a foot in diameter, allowing enough in addition for two short arms. Cut off about 3 ft. 8 in., which will allow for joints; divide this so that one half is about an inch and a half longer than the other; make one end of the longest piece into a small loop, cranking it at the bottom, as shown at C; one end of the other piece is then thrust through the loop at A, turned round, and beaten down, forming as it were two links of a chain; this acts as a hinge, and allows the net to be doubled. The other end is then cranked, as shown at B, but shorter than the arm C.
Next procure sufficient of the material known as black "holland," which sew all round the ring of the net in such a manner that it does not interfere with the working of the hinge. For this purpose a strip of about 2 in. wide will be enough, which, doubled over and hemmed at the bottom, allows sufficient for the net — a bag made of the material called "leno" — to be subsequently affixed. About a yard of "leno" suffices for the bag, and the pieces which come off the bottom during the operation of rounding it, form "gussets" to fill the net in up to the point where the arms B and C first spring.
To fit this net ready for use, get an ordinary walking-stick, a portion of which is shown at A (Fig. 42), in which bore two holes, one on each side, to receive the little returns shown at B and C (Fig. 41), and at such a distance from the top of the stick as is determined by the length of the arms. With a 0.125 in. gouge or chisel, groove out the wood from these holes to the end of the stick, until the arms of the net just, "bed" up level with the surface.
The arms being nicely adjusted, remove the net temporarily from the stick. Next procure a piece of brass tube from 2 in. to 2.5 in. long, and of sufficient diameter to slip from the point of the stick until it passes the last hole (a 0.625 or 0.75 in. diameter will be found a generally suitable size). On the extreme point of the stick affix an ordinary walking-stick ferrule of such a size and thickness as not to allow the tube to slip off. To fix the net, slip the tube up the stick past the last hole, and placing the little cranks, B and Q in their proper holes, the remainder of the arms properly "bedded" in the grooves, slide the tube D (Fig. 41) up to the point of the stick, as shown in Fig. 42, and the net is thus effectually locked and ready for use.
Fig. 42 — "Ring"-net complete.
I claim for this net the following advantages: That it is the most easily made, the strongest, and the most easily taken down of any net known; added to which its joint A, which does not in the least weaken the frame, allows it to be folded in half the space taken up by the "ring net" or the ordinary "landing net" arrangement. (Note for fishermen: Landing nets, formed as Fig. 41, I have found very useful, as they take up less room in the fishing basket, and are quite as quickly put together as by the screw and socket arrangement.)
Larger nets than are generally used in this country will of course be necessary when collecting such insects as form the genus Ornithoptera or Morpho. For collecting abroad no net will be found more serviceable than a large and strong one, made as Fig. 41; and really when you have five large papilios in your net at one time, as I once had, you require one a little out of the common. A short handle to the net will be found more useful than a long one for collecting some insects, but a brass telescopic handle can be easily made by any gasfitter, and used either long or short as expediency directs.
