The honey which fills the store cells is intended for daily consumption, and also intended as a reserve for the period when the flowers furnish no more. The empty cells are left open, the workers making use of them when they want them, particularly during rainy days, which keep them at home. But the cells which contain the honey put by in reserve are closed. "They are," says Réaumur, "like so many pots of jam or jelly, each one of which has its covering, and a very solid covering it is too." This covering, composed of wax, hermetically seals the pots containing this reserve of honey. The object of this is to keep the honey in a certain state of liquidity, by preventing the evaporation of the water it contains. It is a remarkable fact that it does not run out of the cells which are open, although their position is almost always horizontal. This is because there are always in the sides of these narrow tubes points enough to keep it in, and that besides this the last layer of honey is always of greater consistency than the liquid in the interior, and upon which it forms a sort of crust. When the harvest has been abundant, many combs of closed cells may be found in each hive, perfect storehouses of abundance, furnished for the wants of the bad season. When the construction of the cells goes on well--often on the day after the bees have installed themselves in their hive--the queen goes out to meet the males. At the hour when these are accustomed to disport themselves in the sun, that is to say, from noon till five o'clock, she leaves the hive, whirls about for a few seconds, and disappears into the air. At the end of half an hour she returns, pregnant.
