PREPARING FOR THE HARVEST 181 
where. Drone combs are not especially objectionable in extract- 
ing supers, as long as the queen does not have access to them. 
The productive bee-keeper, however, should avoid having them 
built in the first place, as they should never be permitted in the 
brood chamber, and, unless excluders are used, the queen will 
sometimes be laying in the extracting supers. It is highly desir- 
able that every comb be so perfect that it can be used in any 
part of the hive for any purpose needed. 
Aside from the necessity of avoiding the drone comb, it is

possible to get so much better combs by the use of foundation, and 
to have them built so much more rapidly, that it is economy to 
use full sheets anyway. It is very annoying to have crooked 
combs to deal with, and perfect combs cannot always be secured 
without the use of foundation (Fig. 91). 
For extracting purposes, it is important, also, that the combs 
be built in wired frames (Fig. 92). It makes little difference 
to the comb honey producer whether his combs are wired or not 
after they are once built, because they are not subject to much 
strain. In the extractor, unwired combs are likely to be badly 
broken or ruined altogether. Fig. 93 shows a full sheet of 
foundation ready for the bees. Four horizontal wires are used
