It was formerly the plan, after removing the queen from a colony in order to secure queen cells, to trim the lower edges of the combs containing eggs or very young larvæ, or to cut out strips of comb about an inch wide just below worker cells containing eggs or just-hatched larvæ. This practice gave the bees space in which to build perfect full-sized cells, but it had certain disadvantages. Good worker combs were mutilated, often quite ruined, in order to secure the construction of the cells and also in cutting out the latter. Cells so formed are often in groups so close together that they can not be separated without injury to numbers of them, necessitating, if desirable to save all, a close watch, or at least frequent examination, for hours or even days, since all the queens are not likely to emerge at the same time. To remedy this Mr. O. H. Townsend, of Michigan, devised a plan which is described in Gleanings in Bee Culture for July, 1880 (Vol. VIII, p. 322). It consists in cutting combs whose cells contain eggs or freshly hatched larvæ into narrow strips and pinning or sticking these on the sides of brood combs in such a manner that the cells containing the eggs or larvæ from which queens are desired shall open downward. Mr. Townsend removed the larvæ from some of the cells, believing that he secured better developed queens by limiting the number, and also because he could then cut them out more easily for insertion in separate hives. In the succeeding number of Gleanings (August, 1880), Mr. J. M. Brooks, of Indiana, illustrated a plan for securing even greater regularity. This consists in shaving off the cells on one side down nearly to the midrib of each strip of worker comb containing the eggs or larvæ selected to rear queens from, and then sticking these strips on the undersides of horizontal bars nailed in ordinary comb frames. Mr. Henry Alley, in his work on queen rearing, published in 1883, recommends sticking the prepared strips, shallow cells downward, on the lower edges of combs which have been trimmed so as to round downward. This leaves plenty of space for the full development of queen cells, the eggs or larvæ in alternate cells having been removed as in the plans previously mentioned. All conditions being favorable, many cells conveniently located are thus secured, and if the exact age of the eggs or just-hatched larvæ has been noted the time the young queens will emerge may be known beforehand, so that preparation can be made for them. Nuclei--small clusters of bees containing a quart to two quarts--are to be placed in separate hives and given combs, emerging brood, and a supply of food, and to each of these a mature cell is to be given. The nuclei thus prepared may be confined to their hives with wire cloth and placed in a cellar for two or three days, and when set out, just at dusk (p. 117), the bees will adhere to their new location. Full colonies, whose queens it is desired to replace, may also be made
