👉 The March number of the American Bee Journal contained a call for a meeting of the Michigan Bee-keepers’ Association, to be held at Lansing, on the 23d and 24th of that month.--Bee-keepers from other States and the British Provinces were invited to attend that meeting, as it was _proposed then to make arrangements for holding a_ NATIONAL BEE-KEEPERS’ CONVENTION. The Association met accordingly, and it was resolved to hold a _National Convention_ at Indianapolis, (Ind.) on the 11th and 12th instant, but the time was subsequently changed to the 21st and 22d of December next, as better suiting the convenience of bee-keepers. The _place_ designated seems now, however, for some reason, to have become objectionable to certain parties who probably have “axes to grind.” They are now laboring hard to effect a change; but we presume the effort will fail, as we are assured from various quarters that the Convention will be held at Indianapolis. * * * * * A patent has recently been granted for a method of excluding bee-moths from hives by means of a long lever operated by a hen-roost. The inventor claims “a combination of a vibrating roost or perch for fowls with the slides or doors of one or more bee hives, when so constructed and arranged that the weight of the fowls upon the roost shall close the hives, and their removal from the roost shall open the doors.” How this ingenious contrivance came to be patented at this late day, we do not know; but certainly it is neither, “new” nor “useful.” The same thing was tried and abandoned many years ago, as will be seen by reference to Langstroth’s “_Hive and Honey Bee_,” page 263, first edition. Possibly there is some new “modification” or some novel “combination” of material (chickens included), on which the claim to a patent is based; but unfortunately, no modification or combination can ever enable him who employs this contrivance to circumvent the moths thereby. * * * * * When a colony in an apiary is found to be queenless, and has been so till all the brood has matured, it will generally be found difficult to get the bees to raise a queen from brood inserted, or even to accept and cherish a sealed queen cell. Repeated trials are usually necessary, and when successful the population has generally so dwindled, before the new generation attains the working age, that the colony is of little value, especially late in the season. The better mode is to introduce at once a fertile prolific queen from some populous colony, and let the latter do the queen raising; unless we have fertile queens in reserve in nuclei. With the transferred queen, several combs of brood taken from other strong colonies, should, if possible, be given to the one that has been queenless. The desired object will thus be more speedily attained, and frequently with benefit to the colonies drawn on. The European Sparrow.
