The box of drones may be so placed against the front end of the bottom-board that all the young bees, if any are left in the box, may run out, leaving the drones below the metal to perish. Just such a frame as is used for the wire screen cover may be used to nail the metal to, as the entire top of the box should be covered in order to catch all the drones. How to catch and destroy drones in full colonies will be explained under the head of “Drone and Queen-traps.” DESCRIPTION OF QUEEN-CELL FRAME In my early experience in rearing queens I used combs in standard L frames to attach the strips of comb containing the eggs for queen-cells. While such an arrangement worked well in 3-frame nucleus colonies, there are disadvantages in so doing when used in full colonies and by my present system of queen-rearing; therefore I adopted the all-wood frame and in combination with the wood-strips as shown in fig. 5 and it works nicely. [Illustration: Figure 11] The frame is a standard L style into which are nailed two pieces of wood A A. There are four notches cut in on the inner edges two inches a part, into which the four pieces of wood are placed and are thus held firmly in position. By examining the queen-cells illustrated in fig. 5, it will be seen that they are long and pointed, also very heavily waxed and corrugated. They do not much resemble the row of queen-cells lately illustrated in one of the bee-papers. The heavy waxing and large, long cells are the strongest indications that such cells contain very hardy and perfect queens. Fig. 9 illustrates a perfect queen-cell, while fig. 10 shows a queen-cell that always contains inferior queens. Queen-cells that are short, blunt-end, thin-walled and thinly waxed, as shown in fig. 10, contain very inferior queens, and all such cells should be destroyed. They are just such queen-cells as bees make when they have a queen of any kind in the hive. The cells shown in fig. 5 were built in a powerful queenless colony late in September, 1902, and were the last lot of cells built in my apiary that season, consequently not as many cells were built as would have been the case had the season not been quite so far advanced, yet the number of cells are as many as the strongest colony of bees should be allowed to build or finish up from the 24-hour cell-cups. The mistake many queen-breeders make is in permitting one colony of bees to build so many cells in one batch. [Illustration: Figure 12]
