MOVABLE-FRAME HIVE3.

" knife edge," C, on another tin edge, at right angles with 

 it. A., nailed in the rabbet of the hive, the bees cannot 

 glue the frames fast. But these frames have the dis- 

 advantage of getting out of place easily, too easily in fact, 

 and their sharp edges make them very inconvenient to 

 handle. 



326. For the L. Quinby suspended frame, see diagram 

 (fig. 68). This frame is one-fourth inch deeper than that 

 originally given by Mr. Quinby in his "Mysteries of Bee- 

 keeping." Mr. Quinby had too much space in the hive, 

 under the frame. 



327. It is necessary that the hive should always slant 

 forward, toward the entrance, when occupied by bees, to 

 facihtate the carrying out of dead bees, and other useless 

 substances ; to aid the colony in protecting itself against 

 robbers, to carry off moisture, and prevent rain from beat- 

 ing into the hive. 



328. For this, and other reasons, the combs should run 

 from front to rear, — so as 

 to hang perpendiculaxly 

 — and not from side to side 

 as they do in the Berlepsch 

 hive. 



329. The Langstroth 

 hive, from the simple form 

 given in fig. 64, was im- 

 proved upon in many dif- 

 ferent ways. The Standard 

 Langstroth hive has been, 

 for a long time (fig. 63), 

 a hive with por-tico, 

 honey-board, permanent 

 bottom-board, and ten 

 frames.
