Various have been the contrivances for effecting the separation of storage and breeding departments in a hive. […] An empty box or hive, pushed beneath a full one, is denominated a Nadir,—a mode of practice not always advisable except in the case of swarms of the same year, or towards the latter end of very abundant seasons. A still smaller addition to a common hive consists of merely a few bands of straw, on which it is raised temporarily, and this constitutes an eke. […] The entrance to the stock-hive must be stopped, and one made at the bottom of the eke or nadir.
