Again, in the late summer, when supplies of honey from the fields begin to fail, the workers, even in a flourishing hive, will not only worry to death, or drive away to destruction, all the males which are adult, but will pull out of the cells the immature drones, and carry them from the hive. In this case we have two independent judgments. First, that, having a fertile queen, but no probability of further swarming, no _raison d'être_ exists for the males among them; and secondly, that the unhatched males would, on emerging from the cells, be useless consumers of precious stores, and consequently are better destroyed. Numerous other evidences of judgment might be adduced, such, for instance, as building drone-comb, _i.e._ cells of large size, when unusual space is required for quick storing of food, the different expedients for repairing, refixing, and giving direction to combs, in view of various difficulties to be encountered. But we have said, we believe, sufficient to make good the special point in question. We might, perhaps, with advantage, have spoken of the faculty of _attention_, _i.e._ the direction of the mental powers to a particular end by the determinate action of the will. At every moment we may see, in a busy hive, evidences of this power. Indeed, in so complex a community, where so many operations are constantly going forward, where so many stages of social development are being passed through, where so many separate interests have to be regarded, and where the harmonious co-operation of individuals is of supreme importance to the general welfare, it is impossible that this faculty of attention should be wanting or unexercised. We have hinted at the prevision shown by bees. Now, if this really exists in them, we must acknowledge it to be one of the very highest endowments of intellect It is that which in man removes him from the sport of circumstances, and gives him large control over his own earthly destinies. It is that which, when applied to events more or less unascertainable by the majority of men, proportionately awakes their astonishment, and creates a reputation for ability and high endowment. Now, that the faculty is possessed by bees is, we think, evident from many considerations. When, for instance, a hive has lost its queen, and has no hope of a successor, despair comes over the community, as the workers feel they have no longer an object in their toil. They seem to foresee the speedy end of their colony, and the consequent uselessness of collecting stores, or proceeding with comb-building. Again, the destruction of the drones and drone-brood, when no longer of possible service, implies a knowledge that the males, if spared, will produce a scarcity of food, by uselessly consuming the stores, while the preservation, to a late period, of drones in a hive whose queen is lost near the end of summer, indicates a foresight of the possible need of males to mate with a young queen, whose advent is hoped for.
