We need not concern ourselves with this incomplete attempt of mine, for many other curious traits compel us to recognise the existence among the bees of spiritual communications that go beyond a mere "yes" or "no," and that are manifest in cases where mere example or gesture would not be sufficient. Of such, for instance, are the remarkable harmony of their work in the hive, the extraordinary division of labour, the regularity with which one worker will take the place of another, etc. I have often marked bees that went foraging in the morning, and found that, in the afternoon, unless flowers were specially abundant, they would be engaged in heating and fanning the brood-cells, or perhaps would form part of the mysterious, motionless curtain in whose midst the wax-makers and sculptors would be at work. Similarly I have noticed that workers whom I have seen gathering pollen for the whole of one day, will bring no pollen back on the morrow, but will concern themselves exclusively with the search for nectar, and vice-versa. {48} And further, we might mention what M. Georges de Layens, the celebrated French apiarist, terms the "Distribution of Bees over Melliferous Plants." Day after day, at the first hour of sunrise, the explorers of the dawn return, and the hive awakes to receive the good news of the earth. "The lime trees are blossoming to-day on the banks of the canal." "The grass by the roadside is gay with white clover." "The sage and the lotus are about to open." "The mignonette, the lilies are overflowing with pollen." Whereupon the bees must organise quickly, and arrange to divide the work. Five thousand of the sturdiest will sully forth to the lime trees, while three thousand juniors go and refresh the white clover. Those who yesterday were absorbing nectar from the corollas will to-day repose their tongue and the glands of their sac, and gather red pollen from the mignonette, or yellow pollen from the tall lilies; for never shall you see a bee collecting or mixing pollen of a different colour or species; and indeed one of the chief pre-occupations of the hive is the methodical bestowal of these pollens in the store-rooms, in strict accordance with their origin and colour. Thus does the hidden genius issue its commands. The workers immediately sally forth, in long black files, whereof each one will fly straight to its allotted task. "The bees," says De Layens, "would seem to be perfectly informed as to the locality, the relative melliferous value, and the distance of every melliferous plant within a certain radius from the hive.
