Simmins’ Thick Top-bar. 
Having used a top-bar from #-inch to $-inch thick for 
more than 30 years, during the whole of which period I 
have strongly condemned the thin 38-inch bar generally 
manufactured by hive-dealers, 1 am so strongly convinced 
as to the superior advantages of the thick top-bar that I 
must urge all to use no other. 
The thick bar is not so readily built over by the upward 
extension of the comb, while I have frequently pointed 
out that the queen is less likely to travel over it into the 
supers, hence one reason why excluder zinc may be 
dispensed with. I have carried out so 
Many Experiments with Frames 
in various styles that my readers may be assured the 
plain frame {$-inch wide is the best to adopt as herein 
illustrated. Top-bars varying from I-inch to 14-inch. 
have repeatedly been tried, only to be discarded as non- 
practical, except in the case of shallow extracting frames, 
which may have 14-bars and be spaced at 1#-inch. Frames 
with wide ends for stock purposes should be barely 14-inch. 
SIMMINS’ CONQUEROR “ HANGING-CHAMBER ” 
HIVE. 
In hive construction I presented in my 1893 edition the 
very novel feature of whole bodies HANGING as do the 
brood frames, and notwithstanding the clear bee-space 
allowed all round between each upper and lower rim of 
the respective boxes, the sections are carefully secured 
against cold by the judicious arrangement of the quilting ; 
while upward ventilation around the sides may be allowed 
or entirely prevented at will, simply by the careful adjust- 
ment of the same. The section crates are further secured 
against chill by double packed sides.
