BEE MANUAL. 237 
Mr. Heddon, who appears to be a thoroughly careful and 
observant apiarist, has had several thousand reversible frames 
in use for the past two seasons, and states in his report to 
Gleanings for July, 1885 :— 
**T heve to report not only practical success in their manipulation 
(the second year of their use), not only as far as gluing, etc., is con- 
cerned, but the generally conceived advantages of reversing are more 
than realised. he comfort of frames solid full of comb, and that 
comb nearly solid full of brood, is pleasing to the eye of the apiarist. 
I find the three-fourths space between the lower half of the end of the 
frame and the hive a great advantage. A few hives that were over- 
looked, and became clogged with honey, crowding out the queen, had 
to have the brood-combs extracted. Before replacing them with the 
bees we reversed them, giviny plenty of surplus room above, and this 
reversing prevented any further clogging of the brood-frames. I am 
pleased beyond expectation, and never expect to use anything else but 
reversible frames for either comb or extracted honey production.” 
HEDDON’S REVERSIBLE FRAME. 
Scores of devices have been suggested for making frames 
reversible without altering the hives; but Mr. Heddon’s 
(shown in the following engraving) appears to be as simple and 
practicable as any, and the fact that he has found it to answer 
so well is a strong recommendation in its favour. 
On reference to the figure it will be seen that the frame 
consists of an ordinary top bar, to which aze attached two 
short end bars, with a rectangular frame pivoted between them ; 
—it is very simple and easily made. For a Langstroth frame 
the rectangular frame should be 17 inches long hy 8} inches 
deep, outside measure, and made out of three-eighth-inch 
material, one of the longest sides having a groove to fasten 
comb-foundaticn in when wires are not used. The short end 
bars to which the frame is pivoted should be about 5} inches
