After we have removed all the queen-cells, in manner soon to be described, we can again supply eggs, or newly-hatched larvæ--always from those queens which close observation has shown to be the most vigorous and prolific in the apiary--and thus keep the same queenless colony or colonies, engaged in starting queen-cells till we have all we desire. Yet we must not fail to keep this colony strong by the addition of capped brood, which we may take from any hive as most convenient. I have good reason to believe that queen-cells should not be started after the first of September, as I have observed that late queens are not only less prolific, but shorter lived. In nature, late queens are rarely produced, and if it is true that they are inferior, it might be explained in the fact, that the ovaries remain so long inactive. As queens that are long unmated are utterly worthless, so, too, mated queens long inactive are enfeebled. In a week the cells are capped, and the apiarist is ready to form his NUCLEI. A nucleus is simply a miniature colony of bees--a hive and colony on a small scale, for the purpose of rearing and keeping queens. We want the queens, but can afford to each nucleus only a few bees. The nucleus hive, if we use frames not more than one foot square, need be nothing more than an ordinary hive, with chamber confined by a division-board to the capacity of three frames. If our frames are large, then it may be thought best to construct special nucleus hives. These are small hives, need not be more than six inches each way, that is, in length, breadth, and thickness, and made to contain from four to six frames of corresponding size. These frames are filled with comb. I have for the last two or three years used the first named style of nucleus hive, and have found it advantageous to have a few long hives made, each to contain five chambers, while each chamber is entirely separate from the one next to it, is five inches wide, and is covered by a separate, close-fitting board, and the whole by a common cover. The entrance for the two end chambers is at the ends near the same side of the hive. The middle chamber has its entrance at the middle of the side near which are the end entrances, while the other two chambers open on the opposite side, as far apart as is possible. The outside might be painted different colors to correspond with the divisions, if thought necessary, especially on the side with two openings. Yet I have never taken this precaution, nor have I been troubled much by losing queens. They have almost invariably entered their own apartments when returning from their wedding tour. These hives I use to keep queens during the summer. Except the apiarist engages in queen-rearing extensively as a business, I doubt the propriety of building such special nucleus hives. The usual hives are good property to have in the apiary, will soon be needed, and may be economically used for all nuclei. In spring
