In France, floating bee-hives are very common. One barge contains from sixty to a hundred hives, which are well defended from the inclemency of the weather. Thus the owners float them gently down the stream, while, they gather their honey from the flowers along its banks; a single bee-house yields the proprietor a considerable income.

The bee hives were placed on barges that would start up the Nile and as the season changed the barges floated downstream, 30 miles at a time, at night so the bees were always in a honey flow area.
