50 PROFITABLE BEE-KEEPING 
is néeded, but it should be seen to that the tops 
of the brood-combs are scraped clear of projecting 
brace-combs and a sheet of excluder zinc laid 
over them, the slots of which should run at right 
angles to the frames. This excluder zinc is simply 
a sheet of slotted zinc which will admit of the 
passage of the workers but not of the queen. 
The object is to prevent the queen using the super 
for breeding, to the detriment of the shallow 
frames kept solely for honey producing purposes. 
This zinc may be omitted in using section racks, 
but it should always be used under shallow frames. 
The reason of this is that the queen has a great 
objection to passing through the narrow entrances 
of section boxes, but will freely pass up into a 
shallow frame super. Having the zinc in position, 
place the super directly down upon it, and cover 
all up as warmly as possible. When the first super 
is two-thirds full of honey the second one may be 
given, placing it under the first. By the time 
the third super is needed, if one is needed, the 
top one will be ready to come off. 
Always place the last super given next the 
brood-chamber, that is, underneath all the others, 
except towards the close of the season. If, how- 
ever, there are signs that the honey flow is failing, 
although the bees require more room, the last 
super may be placed at the top, when the bees 
will only. use it if necessary. 
The management when comb honey is worked 
for differs in no vital particular from the above,
