A variation upon this is "The New Round Feeder," which obtained a prize at the 1875 Crystal Palace Bee Show. It is made of wood, and holds more than two pounds of liquid food, which must be poured into the outer trough. The bees ascend through the centre as in the last case, and passing over the innermost ridge, which is rounded, they reach the inner trough, at which they imbibe the food without risk of drowning, as the sides are too contracted. A piece of window glass covers the top. The feeder is nearly ten inches in diameter. § XXI. FUMIGATORS. [Illustration] The "Box Fumigator" is a tin case, somewhat like a pepper-box upon a foot. It is a simple adaptation of the fumigating apparatus described by Mr. Nutt, and is used in the following manner: Have a straw hive or other vessel ready that will match in circumference the hive intended to be fumigated. If the empty hive have a conical top it will not remain crown downwards without a rest; in this case it will be convenient to invert it on a pail. Having ascertained that the hive to be operated upon and the empty one in its reversed position nearly match in size, take half a packet of the prepared fungus, fire it well, and place it in the box or fumigator; place this in the centre of the empty hive, then bring the occupied hive directly over, so as to receive the fumes of smoke. To keep all close, put a wet cloth round the junctures of the two hives. After a minute or two the bees may be heard dropping heavily into the lower empty hive, where they lie stupefied. After a little while the old hive may be gently tapped upon to make them fall more quickly. On removing the upper hive the bees from it will be found lying quiet at the bottom of the lower one, when the intended operation--of uniting different colonies, searching for the queen, or whatever else it may be--must be promptly performed. [Illustration] The "Tube Fumigator," which will be found to possess many advantages over the above, is useful for several purposes. When a frame hive has to be disturbed it is requisite to raise the lid and blow a little smoke into the hive, so as to check the angry passions of the bees. If it be desirable to stupefy the bees, ignited fungus must be placed in the box and the flattened end applied to the entrance of the hive; the smoke is then blown in, either with bellows or by applying the mouth of the operator, taking care to close all openings through which it can escape. The bees fall down stupefied, generally in about ten minutes; but the effect varies according to the populousness of the hive and the quantity of comb in it. The projected operation must now be performed speedily, as activity will soon be regained. See preceding directions.
