“Pliny states that the custom of removing bees from place to place for fresh pasturage was frequent in the Roman territories, and such is still the practice of the Italians who live near the banks of the Po, (the river which Pliny particularly instances) mentioned by Alexander de Montford, who says that the Italians treat their bees in nearly the same manner as the Egyptians did and still do; that they load boats with hives and convey them to the neighbourhood of the mountains of Piedmont; that in proportion as the bees gather their harvest, the boats, by growing heavier, sink deeper into the water; and that the watermen determine from this when their hives are loaded sufficiently and it is time to carry them back to their places from which they came. The same author relates that the people of the country of Juliers used the same practice; for that, at a certain season of the year, they carried their bees to the foot of the mountains that were covered with wild thyme.”
