194 Reversible or Invertible Frames. 
For the past two years I have used the reversible frame, 
which I find so valuable that I shall use‘it largely in future. 
With this frame there is no danger of the top-bar sagging, 
which is sure to enlarge the bee space above and create 
mischief, and by inverting we secure the firm attachment 
of the comb to the frame along all its edges, and can force 
Fic. 70. 
Reversible Frame, Upper one hung in the Hive, Lower one partly Reversed,

harvest. I have sent reluctant bees into the sections repeat- 
edly, simply by inverting the combs. This may not always.

frames are a success; “they have come tostay.” Figure 7o 
shows the character of the reversible frame as made by 
Mr. Heddon and which I have found to work the best of 
any that I have used. As will be seen the reversible part 
is a rectangle, pivoted in the center to the bottom of the 
short end-bars. These short end-bars at the top come within 
one-fourth (1 ) inch of the side of the hive, and thin a little 
as they run down, so that the lower end is three-eighths 
(3) of an inch from the side of the hive. The bottom of 
the frame, indeed all below the short end-bar, is three-
