cells. The comb is built up rapidly, in fact so rapidly as to 
be considered a disadvantage at times, in that brood is so 
quickly reared that the increase in population may again 
induce swarming. The use of full sheets of foundation may 
increase the work done in the brood-chamber, at the expense 
of the surplus. 
Narrow strips of foundation, perhaps an inch wide or less, 
may be used, and this usually results in slow progress in the 
construction of combs in the 
brood-chamber. The bees 
then do more work in the 
supers, if they have been 
started, and it is so long be¬ 
fore the colony can rear much 
brood that they rarely at¬ 
tempt to swarm again in the 
season. However, combs 
built on strips of foundation 
often contain many drone 
cells, especially if the comb 
building in the brood-cham¬ 
ber progresses faster than the 
cells are filled with eggs by „ _ , , , 
the queen or when comb is board”), 
built outside the space needed 
for brood. If the parent colony has a brood disease, the use 
of strips of foundation is preferable, thus combining swarm 
management and disease treatment. When either strips of 
foundation or full sheets are used and partly drawn combs 
are present in comb-honey supers, the queen may go above 
to lay eggs and this should be prevented by the use of the 
queen excluder (Fig. 115) for a few days or until there is 
room for egg-laying below, when the excluder may be re¬ 
moved. If the supers are left off for a time, work will 
progress in the brood-chamber so that space for egg-laying 
will be available there and the queen will not go to the supers. 
One or two empty combs may be used in the brood-cham-
