The bees seem to make a provision for this emergency, the sheets of comb are farther apart than actually necessary at first, the diameter of the cell is also a little larger than the size of the young bee requires. _Of this we are certain_--great many young bees _can_ be raised in a cell, and not be diminished in size, sufficient to be detected. The bottom fills up faster than at the sides, and as they do so, the bees add a little to the length, until the ends of these cells on two parallel combs approximate too close to allow the bees to pass freely; before which time it is unnecessary to remove comb for being old. EXPENSE OF RENEWING COMBS. One important item should be considered in this matter, by those who are so eager for new combs. It is doubtful whether one in 500 ever thought of the expense of renewing comb. I find it estimated by one writer,[2] that twenty-five lbs. of honey was consumed in elaborating about half lb. wax. This without doubt is an over estimate, but no one will deny that some is used. [2] See Appendix of Cottage Bee-keeper, page 118. BEST TO USE OLD COMBS AS LONG AS THEY WILL ANSWER. I am satisfied of this much, from actual experience, that every time the bees have to renew their brood-combs in a hive, they would make from ten to twenty-five lbs. in boxes, hence I infer that their time can be more profitably employed than in constructing brood-combs _every year_. I would also suggest that when combs have been once used for breeding it is the best use they can be applied to, after that, as the cocoons render it unfit for much else than a little wax. METHOD FOR PRUNING WHEN NECESSARY. But when the combs do actually need removing, I prefer the following method of pruning, to driving the bees out entirely, as has been recommended. It can be done in about an hour. As we are comparing the merits of different methods of getting rid of old combs, I shall give mine here, notwithstanding it may seem a little out of place.
