To those who limit the fertility of the queen to 200, or at most 400 eggs per day, the rapid replenishing of the hive after swarming, must ever be a problem incapable of solution; but to those who have ocular demonstration that she can lay from one to three thousand eggs a day, it is no mystery at all. A sufficient number of bees is always left behind, to carry on the domestic operations of the hive, and as the old queen departs only when the population of the hive is super-abundant; and when thousands of young bees are hatching daily, and often 30,000 or more, are rapidly maturing, in a short time the hive is almost as populous as it was before swarming. Those who assert that the new colony is composed of young bees which have been forced to emigrate by the older ones, have certainly failed to use their eyes to much advantage, or they would have seen, in hiving a new swarm, that it is composed of both young and old; some, having wings ragged from hard work, while others are evidently quite young. After the tumult of swarming is entirely over, not a bee that did not participate in it, seeks afterwards to join the new colony, and not one that did, seeks to return. What determines some to go, and others to stay, we have no certain means of knowing. How wonderfully abiding the impression made upon an insect, which in a moment causes it to lose all its strong affection for the old home in which it was bred, and which it has entered, perhaps hundreds of times; so that when established in another hive, though only a few feet distant, it never afterwards pays the slightest attention to its former abode! Often, when the hive into which the new swarm is put, is not removed from the place where the bees were hived, until some have gone to the fields, on their return, they fly for hours, in ceaseless circles about the spot where the missing hive stood. I have often known them to continue the vain search for their companions until they have, at length, dropped down from utter exhaustion, and perished in close proximity to their old homes! It has been already stated that the old queen, if the weather is favorable, generally leaves about the time that the young queens are sealed over, to be changed into nymphs. In about eight days more, one of these queens hatches, and the question must now be decided whether any more colonies are to be sent out that season, or not. If the hive is well filled with bees, and the season in all respects promising, this question is generally decided in the affirmative; although colonies often refuse to swarm more than once when they are very strong, and when we can assign no reason for such a course; and they sometimes swarm repeatedly, to the utter ruin of both the old stock, and the after-swarms.
