As to the width of hives and consequent number of frames each story is to hold, there has been of late much diversity of opinion. The original Langstroth hive held ten frames in the lower story and eleven frames in the second or top story. A demand for smaller-sized brood chambers and uniformity of the stories having been created, the larger hive-manufacturing establishments gave hives constructed to hold eight frames the most prominent place in their catalogues, and by many it was considered that those who adhered to the older, larger form did so merely through conservatism. But after some years' trial a reaction in favor of larger hives seems to have set in, especially among producers of extracted honey. Many of the latter are finding that with carefully bred queens even twelve-frame brood apartments give the best results. The author's experience of over twenty-five years with frame hives of various sizes and styles, both American and foreign, in widely differing climates, convinces him that to restrict a hive to a capacity of less than ten frames for the brood chamber is, in most localities, undesirable, but it will frequently be found advantageous to contract temporarily the space occupied by the bees. For extracted honey alone, especially in any region having a short flow of honey, twelve-frame capacity is preferable. Thin, movable partitions, known as "division boards," enable one to contract the space at will, and the addition of supers or top stories gives storage room for surplus honey. Some prefer to have the hive in one story holding twice the usual number of frames and contractible with a division board. The entrance is then usually at one end, parallel with the combs, and the surplus honey is obtained from the rear part of the hive, either in sections held in wide frames or it is extracted with a machine from ordinary frames. This plan renders access to all of the frames somewhat easier than when two or more stories are used, but as the methods now most followed involve on the whole less manipulation of individual frames than was formerly deemed advantageous this superiority can not count for much--hardly enough in fact to balance the limitation as to the number of frames and the inconvenience of larger and more unwieldy hive bodies, covers, and bottom boards.
