frame-hive

“bar frame-hive;" for the bee-frames form, as it were, a smaller box within the oblong box, and are not in immediate contact with the external air, but have a half inch space nearly all round them, which will to a certain extent maintain an equable temperature for the bees, both in summer and winter.”
