The bees give abundant proof that they are capable of reason. As an instance, we may mention that Andrew Knight, a wellknown student of insect life, once covered the bark of some diseased trees with a kind of cement which he had made out of turpentine and wax. Some time after he noticed that the bees round about were making use of this mixture, which they had tried and adopted; they had found it close to their hive, and appeared to prefer it to their own. As a fact, the science of bee-keeping consists largely in giving the bees the opportunity of developing the spirit of initiative that they undoubtedly possess. Thus the bee-keeper, when pollen is scarce and it is important that there should be food for the larvæ, will scatter a quantity of flour near to the hive. This is a substance that the bees, in a state of nature, in their native forests in Asia, can never have met with, or known. And yet, if care be taken to tempt them with it--if one or two be placed on the flour, and induced to touch it and try it, they will quickly realize that it more or less resembles the pollen of which they are in need; they will spread the news among their sisters, and we shall soon find every forager-bee hurrying to gather this strange food, and supplying it to the infant-bees in place of the accustomed pollen. It is only during the last hundred years that the bees have been seriously studied by man; only fifty years ago that the movable frames and combs were designed by means of which we were able to watch their movements. Need we wonder, then, if our knowledge is still somewhat limited? The bees have existed many thousands of years; we have observed them only for what is relatively a very short time. And if it could be proved that, during that time, no change has taken place in the hive, should we be right in assuming that there had been no change before our first questioning glance? Remember that a century is no more than a drop of rain that falls into the river; that a thousand years glide over the history of nature as a single one over the life of man. It is of interest to compare the honey-bee of the hive with the great tribe of "Apiens," which includes all the wild bees. We shall discover differences more extraordinary than those that exist among men. But let us merely, for the moment, consider what is known as the domestic bee, of which there are sixteen different kinds, all, the largest as the smallest, exactly alike, except for the slight modifications caused by the climate or the conditions in which they exist. The difference between them, in appearance, is no greater than between an Englishman and a Russian, a European or a Japanese.
