Mr. Downing - Your bee correspondent may be assured from my "experience," of the fact that a queen bee has been produced from a worker's egg. I use the common phraseology. The working bees are barren females; the queen the only fertile bee of the hive. If she be lost, or dies, and there be worms [larva] of some three or four days old, which, under ordinary circumstances, would become workers and barren, the bees select one, and by some treatment which no one has yet satisfactorily explained, so develop its organs as to render them generative - and such bee becomes the mother and queen, so called.

The subject is full of difficulties. For not only is the generative power of such bee changed - but her shape, length of body, and sting. The various writers on the subject greatly disagree. Let me refer to "Bet an on the Honey Bee," and "Huish on Bees," and "Miner on Bees and Hives." In these works the subject is fully treated. The probability is, that, as in most contested cases, the truth lies between the parties, and not wholly on one side.

Some years since, in a single combed hive made for the purpose, an apiarian friend and myself witnessed the experiment. The queen of the swarm, from the nature of the hive, could easily be seen at any time. She was killed by a stab with a long knitting needle. In the course of a few hours the bees were found ingreat commotion, and continued so for most of the day. When quiet, it was found that a small knot of bees was clustered round a spot near the center of the comb. - and here they continued, till at the end of about fourteen days a queen was seen to emerge from the cell at which they had operated. Whether the worm was a worm, which, if let alone, and no queen were wanted, would have produced a worker, or whether it was a queen-worm, and which, (whether a queen were wanted or not,) would have been a queen, I leave to the theorists to settle. Of the fact that a queen was had, your correspondent may be assured.

To his second query, I cannot reply practically, but should by all means recommend the parting of the hive, and the removal of one of the parts to at least a mile's distance.

To his third query, I reply that the bees in that part of the hive which contains the queen, will, (whether it be the part carried off or the part remaining at home,) be quiet and easy, and keep about their regular business; while the bees in the part which has not the queen, will soon become troubled and uneasy, and begin to run about and travel over the combs in great agitation, as if in search of the queen. This they will do for some hours, until they settle down under the necessity of the case, and get to work on the process of procuring their new queen.

Tour correspondent appears to keep his bees in a city; now, although I have known bees to do pretty well in town, they do much better in the country. The temptations of the town lead many bees, as well as many bipeds, into dangerous and deadly places. In the early and warm spring, before the honey-yielding flowers have blossomed, and in the late summer, after they have withered. - the sweet odors of the confectionary shops, of the sugar and molasses stores, allure the the town," and all the works and places which hear impress of the Deity, are far letter for bees as well as for bipeds.

"Ron mihi placent ante omnia" The country, the country is the right place for me, The fields and the woods for the sweet socking bee.

Still, if it be his misfortune to be tied down to brick and mortar, and a pavemented town, he had better resort to the "non-swarming hives," and depend for the increase of his stock upon some farmer out of town. My limits, or rather your limits, will not permit the space for the details, or I could give a description of one which I have used for years, without its swarming, and have had an annual produce of honey of from fitly to eighty pounds, without destroying a bee. [We shall be glad to have this description. Ed.] Yours, H. K. 0.
