This cell is large, cylindrical, and extends vertically. In Figure 797 the begin- nings of two queen- cells are represented on the lower edge of the comb, and a completed cell extends over the -l^^^- 797-—Comb of the Honey-bee, with queen-cells. face of the comb near the left side. From the lower end of this cell hangs a lid, which was cut away by the workers to allow the queen to emerge. The larv^ that are to develop into either workers or drones, and which are contained in hexagonal, horizontal cells, are fed with honey and bee-bread. But the occupant of a queen-cell is furnished with very different food—a sub- stance called by bee-keepers royal jelly. This royal jelly is a substance which resembles blanc-mange in color and con- sistency. It is excreted from the mouth by the workers, and is a very nutritious food. It has been demonstrated that in the ^g^ state there is no difference between a worker and a queen. When the workers wish to develop a queen they tear down the parti- tions between three adjacent cells containing eggs that under ordinary conditions would develop into workers. Then they destroy two of the eggs, and build a queen-cell over the third. When the egg hatches they feed the larva with royal jelly, and it develops into a queen. In early summer several queen-cells are provided in each colony; as soon as a queen is developed from one of these the old queen attempts to destroy her. But the young queen is guarded by the workers, and then the old queen.
