A much more convenient frame may be made by thrusting the ends of a piece of cane into the two narrow arms of a metal Y. You may purchase the Y at any of the naturalists' stores, or you can make one yourself if you know how to perform the operation of soldering. I have always made mine with odds and ends of brass tubing such as old gas pipes. One piece must be just the size to fix on the stick; and the other two must fit the cane tightly. The three pieces must be filed off at the proper angles, and the doubly bevelled end of the wider tube must then be flattened down to the width of the smaller ones before soldering. If you decide to buy one, give the preference to strong brass rather than the cheaper and more fragile ones made of tinned iron. [Illustration: FIG. 41. THE METAL Y.] The advantage of such an arrangement over the last frame is evident at once. The cane, with net attached, can be pulled out of the Y when not in use, and bent small enough to go in the pocket or a satchel; and the Y can also be separated from the stick, thus allowing the latter to be used as a walking stick. Some entomologists speak very favourably of what is known as the 'umbrella net'--a large and light net that will shut up like an umbrella, and may even be made to look very much like this useful protector, but the possession of such an imitation is somewhat tantalising in a pelting shower. The ring of this net consists of two steel springs attached to a couple of brass hinges, one of which is fixed near one end of the handle, while the other slides up and down in the gamp fashion. One other form of net--'the clap net'--although still occasionally seen, has had its best days. Two sticks are provided to this one, so that the two sides of the net may be brought together on the insect; but as both hands are required to manage it, it is almost surprising that it ever had any advocates at all. When your frame is completed, sew round it a strip of strong calico, to which the net itself may be afterwards sewn, for the lighter material of the net is too delicate to stand the constant friction against the metal or cane frame. The material usually employed in making the 'bag' is called leno. It can be purchased at most of the drapers' shops, and three colours--white, yellow and green--are usually kept in stock. Measure the circumference of your net frame, and see that you get sufficient leno to make a good full net. Suppose, for instance, that the circle of your frame measures thirty-six inches round, then your leno should be at least forty inches in length. Fold this double, and then cut out two pieces of the shape shown in fig. 42, letting the depth of the net be nearly or quite equal to the width of the material. There is nothing to be done now but to stitch the bag together and sew it to the calico on the ring. [Illustration: FIG. 42.]
