Improved Comb Bar.--Mr. Woodbury says that this little contrivance has proved very effectual in securing straight combs when guide combs are not obtainable. The lower angles are rounded off, whilst a central rib is added of about ⅛ of an inch in breadth and depth. This central rib extends to within ½ an inch of each end, where it is removed in order to admit of the bar fitting into the usual notch. All that is necessary to insure the regular formation of combs is, to coat the underneath surface of the central rib with melted wax. Mr. Woodbury further says, "my practice is to use plain bars whenever guide-combs are attainable, as these can be attached with much greater facility to a plain than to a ribbed bar; but whenever I put in a bar without comb, I always use one of the improved ones. By this method, crooked and irregular combs are altogether unknown in my apiary." Most of our bars are made with the ridge; but should any of our customers prefer the flat ones, we keep a few to supply their requirements. With the moveable "bar and frame hive" every comb is available for extraction, and may easily be taken out of the hive; each comb being fixed within its frame, there is less disturbance to the bees than if the combs were fixed to the sides, as is the case with ordinary hives. A strip of wood, about ½ an inch wide, rests on the floorboard; in this strip are ten notches, made to receive the lower part of the frames, so as to retain them in their places at equal distances from each other. A difficulty is found with a well stocked hive in dropping the frames into the exact notches, so that it is not necessary to have these rack works always in use; but when any movement of the hive is made, it is essential to have the frames firmly fixed by the aid of this contrivance. It is also advisable to have the frames perpendicularly supported until the combs are built, so in order that the frames should hang true, the hive ought to be on the level. A little inclination may be given to it from back to front, causing the hive slightly to fall towards the entrance, so as to allow the moisture inside the hive, caused by the exhalations of the bees, to run off.
