In the following dimensions it is assumed that 13/16-inch tongued-and-grooved lumber is used, that the 10-frame Langstroth hive is in use, and that two hive bodies are employed for each colony, with adequate space above the hive so that, if needed, a third hive body may be put on before time for the removal of the packing. In this packing case the sides overlap the ends. For hives of other sizes the lumber must be cut so as to provide the packing specified in Table I (p. 15). For zones F and G (fig. 5) provision should be made for additional packing by increasing the length of all parts 4 inches, and for zone C a correspondingly smaller case may be made. Bottom of case 44 Inches (exact) by 52 Inches (exact). Sides of case 53-5/8 Inches (exact) by 35-5/8 Inches (minimum). Ends of case 44 Inches (exact) by 35-5/8 Inches (minimum). Telescope cover of case 48 Inches by 56 Inches (minimum). If 6-inch boards (laying 5-1/2 inches) are used, it is desirable to use 7 boards for the height of the case; if 8-inch boards (laying 7-1/2 inches) are used, 5 will be sufficient. In figure 2 only 6 boards, laying 5-1/2 inches, are shown, but in this case no allowance is made for a third hive body in the spring. For the telescoping part of the cover, 4-inch boards are used. As was pointed out earlier, the hives should rest throughout the summer on the floor of the winter case (fig. 1). The plan of putting them in groups of four, two facing east and two west, has much to commend it during the entire year. The bottom therefore should be made strong enough to stand the weight of four colonies without getting out of shape. Since this weight may be over 1,000 pounds in a good year, it is advised that the cleats on the bottom of the case be of 2 by 4 inch material. The supports of the bottom and the position of the cleats should be arranged so that the weight will not rest too largely on the boards, and the stones or bricks used should be directly under the center of the hives when they are in their summer position. Obviously the hives will be moved to the outer corners of the bottom during the summer to facilitate handling. The sides of the case should be so constructed that the cleats which hold the boards together will serve to support the overlapping sides on the bottom. This is clearly shown in figure 2. There should also be a central cleat on the sides to prevent warping, for the cases must be rain-proof. If cleats are properly placed as shown in the illustration, they make the equivalent of a halved joint at the corners. The sides may be held in place and together by nails or by any sort of special hook. The entrances for the colonies during winter should be in the ends of the case, as shown. These will be discussed later.
