Your first box full will be a varied assortment. When you have all you can conveniently pin into three boxes without crowding, you will want to arrange them. If you have begun to study science you will know what "classify" means. Every school is made up of classes. So with insects. You will know by the looks of the insects that certain ones belong together. A good way to start is to put all the butterflies and moths into one box. You may not know what you have done, but you have simply separated the members of the order _Lepidoptera_ from all the others. Look over those that are left and you will see that some, like the blundering June bug, have their wings so placed that a straight line appears down the middle of the back. These belong together, regardless of their colour, size, shape, habits, or other considerations. They belong to the order _Coleoptera_. Grasshoppers, katydids, and crickets belong to another group and can be pinned together. All the flies have two wings, and belong in a group apart from all the four-winged ones. The dragon flies go together. You will have representatives of other orders, less easy to distinguish, but by the time your collection has grown to this extent you will be ready for some beginner's book on entomology, which will make further classification simple enough. As you shift your specimens from one box to another observe a certain regularity of arrangement. The heads should all point in one direction. When pinning a group all of which are about one size, set the pins all in line, in military fashion. How much better they look! This neat, formal arrangement of the specimens adds greatly to your satisfaction and enjoyment of your collection. Avoid crowding and breakage. A dried specimen is almost everlasting, but at the same time it is the most fragile thing you can imagine. As your collection grows in size, value, and interest, you will certainly want wooden cases. Perhaps your manual training teacher will be willing to let you build a box under his direction. A cabinet-maker can make them at one dollar or less, apiece, of well-seasoned basswood.
