A DESCRIPTION OF THE BAR-AND-FRAME-HIVE. THE BAR-AND-FRAME-HIVE. By first giving a general description of the "bar-and-frame-hive," the details of its construction can be better explained afterwards. An oblong box is formed of well seasoned wood of an inch in thickness, about thirty inches long, sixteen inches high, and twelve inches broad; but the size may be varied to suit the convenience or taste of different apiarians. Instead of the lid of the box being flat, it is made in the shape of the roof of a cottage, and with projecting eaves to throw off the wet more effectually. One of the long sides of the box is constructed to open with hinges, and to hang on a level with the _bottom_ of the box, and is held up by means of two quadrants. As many grooves, half of an inch broad, half an inch deep, and about 9-1/2 inches long, are formed, 1-1/8 of an inch apart, in the inside of the bottom of the box as its length will admit.
