the reader makes will, of necessity, be of a form peculiar to his purpose and the location where it is placed. If it is for a fence-corner there will be but two sides to cover with wire-netting; if it be against the fence there will be three sides of netting: the fence forming the other side. In a hundred different ways will the surroundings modify the form of the cages, so, to simplify matters, we will suppose the proposed pen is to stand in the centre of the yard. In this case, To Make a Cage of Galvanized Wire-Netting, you first decide upon the wire and the mesh which are needed for this particular coop, next decide what are to be the dimensions; then, with a hand-saw, cut four wooden uprights exactly the same length, and fasten these posts together, temporarily, as shown in Fig. 23, A, B, C, D. [Illustration: FIG. 26.--Cages and Runway.] The strips connecting the uprights, and forming a box-like frame, should be only secure enough to keep the frame in shape. The nails in the strips must be driven just far enough to hold, leaving the head and enough of each nail above-board to render it a simple task to withdraw the nails when you wish to remove the strips. When the temporary frame or mould is finished (Fig. 23), fasten the end of the wire-netting securely to the front of the upright A with staple tacks, then pass the roll to B (Fig. 24), draw it tight, and with more staple tacks secure it to this upright; continue the same process at C and D, ending at A, as shown in Fig. 24. The arrows show the direction to be observed in passing the netting around the uprights. When all is snug and fastened firmly, nail a footboard and top moulding on, as shown in Fig. 25, after which remove the temporary inside strips, and your coop is done. It has no roof or floor as yet, but the roof can be made of wood or netting, as the occasion may require; the floor may be of wood or earth, to suit the purposes for which it is to be used. In large cages the doors must be framed and set in, as shown in the picture of fox-dens in the illustration of the back-yard zoo, but in small cages a small hole may be cut in the netting--this can be done with an old pair of shears. The square piece of netting from the cut can then be used as a door by fastening one edge with loops of wire to the edge of the opening just made. Picture-wire and copper wire are best for such purpose, because they are pliable and easily handled. The Door
