The metal end method of spacing frames is in my opinion one of the most objectionable features of the British equipment. Combs so spaced, since these spacers contact only at the level of the top-bars, can swing when travelling, unless held down tightly on the rabbets which support them. This, in turn, makes it usual for the bee-space between the frames of the different stories to be allowed below the frames, so that the top-bars shall be flush with the hive walls. Then the bottoms of the super walls rest on the ends of the frames and hold them securely in place, but when we wish to lift a super, the lower edges of the super walls are stuck to the top-bars of the brood frames, and the latter are liable to be raised with the super.
