the interior. The flight-hole has the same length of 
ten inches, and is formed by cutting a full quarter- 
inch out of the hive wall, instead of the floor. This is 
shown at G in the sectional view, while F is a piece 
screwed beneath the porch roof to give it additional 
stability, and provide a groove for two sliding shutters, 
by which the width of the entrance may be regulated 
as desired. Two studs at the ends of these pieces pre- 
vent the shutters from meeting nearer than within 
half an inch, so 
as to do away 
with the fear of 
the colony being 
accidentally 
stifled, and also 
with that of 
crushing bees by 
the meeting of 
the two slides 
but if the total 
closmg of the 
hive is from any 
exceptional rea- 
son desired, the 
doors can be 
taken out and 
transposed with 
each other. The 
floor-board is movable, and can be drawn out without 
disturbing the bees upon the combs, the runners 
upon which it slides being shown in the first figure.
