The Bee World - November, 1935 - Page 124

A correspondent of Le Rucher Belge (August - September) remarks on the frequent variation in size of cells in commercial foundation (especially now that larger sizes are sold). Beekeepers who are careless and do not make sure that they have got all their foundation of one size, are thus apt to get several sizes in one colony. The bees may in consequence avoid breeding in the sizes they do not 'fit,' and if this does not occur, will have workers of several sizes. Combs in such cases should be sorted into sizes at wintering time.
