§ VI. BAR SUPERS. 



To these we have already made considerable allusion 

 under the various hives to which they are applied. They 

 are often made of glass, but many are of wood or even 

 straw. It is desirable that the combs in supers should 

 be made thicker than those for breeding — the bees will 

 in fact deepen their honey cells to almost any extent — 

 and therefore the bars are placed somewhat, further apart 

 than in stock hives, thus allowing of one or two bars less. 

 By gradually widening the spaces between the combs

 inches in thickness. With the shallower form of all 

 the older supers the bars are without frames. The
