4. Comb is usually regarded better for not being more than two or three years old. The usual theory is, that cells fill up by repeated use, and, becoming smaller, render the bees raised in them diminutive. This is not probable, as a known habit of the bee is to clean out the cells before reusing them. Huber demonstrated that bees raised in drone-cells (which are always larger than for workers) grew no larger than in their own natural cells. And as bees build their cells the right size at first, it is probable they keep them so. Quinby assures us that bees have been grown twenty years in the same comb, and that the last were as large as the first. But for other reasons, it is better to change the comb. In all ordinary cases, it is better to transfer the swarm to a new hive every third year. Many think it best to use hives composed of three sections, seven and a half inches deep each, screwed together with strips of wood on the sides, and the top screwed on that it may easily be removed; thick paper or muslin should be pasted around, on the places of intersection, to guard against enemies; the two lower sections only allowed to contain bees--the upper one being designed for the honey-boxes, to be removed. Each spring, after two years old, the lower section is taken out and a new one put on the top, the cover of the old one having been first removed. This is the old "pyramidal beehive," which is the title of a treatise on bees, by P. Ducouedic, translated from the French and abridged by Silas Dinsmore in 1829. This has recently been revived and patented as a new thing. We think with Quinby, that these hives are too expensive and too complicated, and that the great mass of cultivators will succeed best with hives of simple construction. 5. Allowing bees to swarm in their own time and way is better than all artificial multiplication of colonies. If there are no small trees near the apiary, place bushes, upon which the bees will usually light, when they come out. If they seem determined to go away without lighting, throw sand or dust among them; this produces confusion, and causes them to settle near. The practice of ringing bells and drumming on tin, &c., is usually ridiculed; but we believe it to be useful, and that on philosophic principles. The object to be secured is to confuse the swarm and drown the voice of the queen. The bees move only with their queen; hence, if anything prevents them from hearing her, confusion follows, and the swarm lights: therefore, any noise among them may answer the purpose, and save the swarm.
