angular edge, but where comb foundation is used, the flat 

 top bar will be found much better (693). Above all, the 

 outside measurements of the frame must be carefully pre- 

 served.

 the amount of bridges and brace combs (397), built by 

 the bees, between the brood-chamber and the upper stories. 

 A wide top bar, leaving but a narrow space for passage 

 above, will almost altogether prevent the building of bridges, 

 but it has other disadvantages that have rendered it unpop- 

 ular, although some bee-keepers of note — Col. Camm of 

 Illinois, among others — use it. In producing extracted 

 honey (749) these bridges and brace combs do not annoy 

 much. 



324. L. Simplicity Frame (flg. 59). — This frame has 

 been made and sold so largely by A. I. Root, and other 

 dealers, that it is established now. The length of the top 

 bar and the height of the frame are the same as those of the 

 Standard L. Frame, the frame itself being one-fourth inch 

 longer outside. They are sometimes made wjth metal cor- 

 ners invented by A. I. Root (fig. 62).
