Robbers.—As considerable robberies frequently take place in this month among the Bees, attention is required to discover if any hives are attacked; and when it is found to be the case, it will be necessary to narrow the entrance of the hive, so that only one or two Bees at most can go in at the same time. The weak stocks, in general, are those that suffer from pillage. Robber Bees may easily be distinguished from others, for they fly rapidly round the hive, and hover before the entrance for some time before alighting; and when they venture to do so they are generally seized by some of the sentinels which guard the entrance.
Queen Wasps.—The destruction of queen wasps, which are now beginning to make their appearance, will prove the best security against their progeny, those formidable enemies of the Bee. In April and May they are very easily captured, and every one now destroyed would probably have been the founder of a nest, which may be computed at 30,000 at the least.
Moths.—Moths are by far the most dangerous enemies the Bees have to contend with. It is the caterpillars of these moths which gnaw and destroy the combs; and they would soon be ruined by these insects, if the Bees did not offer the greatest opposition to their ravages. The perfect insect (Galleria cerreana and Galleria alvearia) may be seen fluttering about the hive at sunset, from April to October, and should be promptly destroyed whenever observed.
MAY.
The most interesting as well as the most active month in the apiarian's calendar has now commenced; food for his little favourites abounds in every direction, and no fear need now be entertained of famine. The population of the hives will have increased considerably, and drones by this time are making their appearance, which proves that the stocks are in a healthy and vigorous state, and should be a subject of congratulation to every Bee-keeper. "Early drones, early swarms," is a maxim, the truth of which every experienced apiarian is well acquainted with.
To those persons who are managing their Bees upon the depriving system, the time will now have arrived for supplying each stock with a small hive, box, or bell-glass; and should the season prove a favourable one, the supply, also, of a second may be found necessary before the end of the month.
Method of Placing the Bell-glass, Box, or Small Hive upon the Improved Cottage Hive.—Take the moveable piece of straw-work from the top of the hive (see [page 8]), and place it upon the adapting board (see [page 8]); then put the bell-glass, small hive, or box (see [page 8]), upon this adapter, and cover the whole with a milk-pan to defend them from wet. Should a bell-glass be preferred, it must be covered with something that will effectually exclude light. A cover of straw is, perhaps, the best. It is very desirable to fix a piece of clean comb inside the glass, and this may very easily be done by warming the perforated zinc tube, which is sold with the glasses, and then pressing the piece of comb upon it. Should the comb reach from the top to the bottom of the glass, so much the better; for the Bees will then begin to work upon it immediately.
Those persons whose Bees are now in common straw hives may, if they please, commence with the above system at once. Bet them in the middle of a fine clear day, with a strong sharp knife, cut out from the top of the hive a piece of the straw-work, 4 inches in diameter, and then place over the opening the adapting board, &c., as directed above. Should the combs be a little broken at the top of the hive it matters not. Indeed, it is rather to be wished that they should be so; for the Bees in repairing them are induced to carry their work upwards in the glass or box that is given them. This operation may be done without any protection whatever by an experienced person; for if done at a proper time and well managed, not a Bee will take wing. All operations, except joining swarms, should be performed on a fine clear day, and between the hours of twelve and two o'clock. At the same time, such operations are done with much less annoyance to the Bees, as well as with less chance of danger to the operator. I generally perform all the operations required in this system without the defence even of a pair of gloves; but I would not recommend any person to do so until he has had many years' experience in the management of Bees; for being perfectly defended in every part against their stings, gives that coolness and confidence to the operator upon which the happy accomplishment of his intentions so much depends. Coolness and confidence on the part of the operator are essential qualifications; for anything approaching to hurry irritates Bees exceedingly. Indeed, the hand ought never to be hastily removed from one position to another. "Quietness," says Dr. Bevan, "is the surest protection against being stung."
Defence.—The best defence that I have found is a mask of wire similar to a fencing mask, and a pair of very thick worsted gloves. It should be remembered that nothing is either more offensive or more irritating to Bees than the human breath: therefore, the breathing upon them must at all times be most carefully avoided.
Covering for Glasses.—When the Bees are beginning to work in a glass, a cold night generally obliges them to forsake their newly-made combs, and to discontinue their labours, which are seldom resumed till the middle of the next day. To prevent this delay, I would recommend the space between the glass and its cover to be filled with fine tow or wool, the temperature of the glass being thereby kept up, and the Bees enabled to carry on their labours without interruption. Wool is to be preferred from its not being so good a conductor of heat as tow.
