Sectional supers are used by most advanced bee-keepers; they can be bought much cheaper and better than they can be made, and as the most used (and probably the best) size is 4 1/2 in. sq. holding when filled 1 lb. of honey, a case will be described to take that size. A bottomless box (c, Fig. 614) is made of 1/2-in. board, 4 1/2 in. (full) deep, and 16 1/2 in. by 15 1/2 in. outside measurement. Four strips (h. Fig. 614), each 15 1/2 in. by 1 1/4 in. by 1/4 in., are nailed across the bottom of the box, being let in flush; 2 of them are at the outside, the other 2 at equal distances, forming 3 equal spaces between; 4 strips (i, Fig. 614) 14 1/2 in. by 1/2 in. by 1/2 in. are nailed on the top of the wide strips, the 2 outer ones against the sides of the box, the others on the centre of the strips. There must be a space of a little more than 4 1/4 in. between these strips, as they serve to keep the sections the right distance apart. 21 sections, 7 in each row, are placed in the case : they do not quite fill it; but a thin board 15 1/2 in. by 4 1/4 in., with notches cut out of the lower edge to fit over the strips, serves to wedge them up together. " Separators " made of tin, or exceedingly thin wood, not thicker than cardboard, each 15 1/2 in. by 3 1/4 in., are placed between the sections, as shown by dotted lines in Fig. 614. They are necessary to keep the combs from bulging into each other : if they are not used, the sections, when filled, can only be packed in the order in which they come out of the hive.
The section case is shown in its place in Fig. 614, but omitted in Fig. 616.
