I shall here describe what may be called a _Queen Nursery_ which I have contrived to aid those who are engaged in the rapid multiplication of colonies by artificial means. A solid block about an inch and a quarter thick, is substituted for one of my frames; holes, about one and a half inches in diameter, are bored through it, and covered on both sides, with gauze wire slides; the wire ought to be such as will allow a common bee to pass through, but should be too small to permit a queen to do the same. Any kind of perforated cover may be made to answer the same purpose as the gauze wire. If a number of sealed queens are on hand, and there is danger that some may hatch, and destroy the others, before the Apiarian can make use of them in forming artificial swarms, he may very carefully cut out the combs containing them, and place them each in a separate cradle! The bees having access to them, will give them proper attention, and as soon as they are hatched, will supply them with food, and thus they will always be on hand for use when they are needed. This Nursery must of course, be established in a hive which has no mature queen, or it will quickly be transformed into a slaughter house by the bees. I have not yet tested this plan so thoroughly as to be _certain_ that it will succeed; and I know so well the immense difference between theoretical conjectures and practical results, that I consider nothing in the bee line, or indeed in any other line, as established, until it has been submitted to the most rigorous demonstrations, and has triumphantly passed from the mere regions of the brain to those of actual fact. A theory on any subject may seem so plausible as almost to amount to a positive demonstration, and yet when put to the working test, it is often found to be encumbered by some unforeseen difficulty, which speedily convinces even its sanguine projector, that it has no practical value. Nine things out of ten may work to a charm, and yet the tenth may be so connected with the other nine, that its failure renders their success of no account. When I first used this Nursery, I did not give the bees access to it, and I found that the queens were not properly developed, and died in their cells. Perhaps they did not receive sufficient warmth, or were not treated in some other important respects, as they would have been if left under the care of the bees. In the multiplicity of my experiments, I did not repeat this one under a sufficient variety of circumstances, to ascertain the precise cause of failure; nor have I as yet, tried whether it will answer perfectly, by admitting the bees to the queen cells.
