It is most urgent in making such a transfer that the most ample ventilation should be allowed. The bees are of course gorged at the time, and in that condition they are most particularly in need of air; while on the other hand the fact of their imprisonment, together with the shaking attendant on carriage, irritates them and causes them to make such a commotion, that without stringent precautions they would very probably be stifled, and of course the finer the colony the greater is the danger.
With an ordinary skep this supply of air cannot be ensured at the top, so that it becomes necessary, if the journey is to last longer than an hour or two, to invert the hive. This must be done with great caution and always in the direction in which the combs run. A sheet of perforated zinc on a board, or a piece of coarse canvas or cheese-cloth, may then be nailed or otherwise fastened with string over the base, thus taking the place of the floor-board, and it is needless to say that this should be done in such a manner that not a single bee can escape. If the journey is likely to be one of more than a few hours it will not do to employ any soft material, as it would in that time be gnawed through; but wire-cloth would answer as well as perforated zinc.
As a preliminary to any remove, smoke should be blown in at the entrance repeatedly during half an hour, after which it may be judged that all on the wing will have returned. For carrying a swarm, either a skep or box or anything will serve, and it must be secured and carried mouth upwards in the same way.
§ XII. SUPPLYING NATURAL COMB.
We have spoken above ([page 187]) of the great value of sheets or strips of wax for assisting the bees in the building of their combs. But when, through another hive having lost its bees at an early stage, the combs themselves can be supplied them in good and clean condition, the advantage is very much greater. Such combs may be fixed in frame hives exactly in the same plan as is adopted on transferring full honeycomb ([page 224]).
Generally speaking the bee-keeper may be satisfied if he can simply insert pure white guide-comb with which to start the bees. Every bar, or if the comb is not plentiful, every other bar, should have a piece fixed to it in the following manner: Cut a piece of clean empty comb of the required size, say two inches square, not less; heat a common flat iron, with which slightly warm the bar; then melt a little bees'-wax upon it; draw the comb quickly over the heated iron, hold it down on the centre of the bar, giving a very slight movement backwards and forwards; then leave the wax to grow cold, and, if cleverly managed, the guide will be found firmly attached. Care must be taken that the pitch or inclination of the comb is the same as it is in the hives—upwards from the centre of each comb.
When a hive has been in use many years the combs become very black, and every bee that is bred in a cell leaves a film behind. It may be understood how in this way the cells become contracted, and the bees that are bred in them correspondingly reduced in size. After the lapse of, say, five years it may be necessary to begin removing the old combs. This may be done by cutting away the combs, or by substituting an empty frame for one with old black comb, gradually moving the frames towards each other. By taking two away in this manner in the spring or summer of every season, the combs in course of five years may all be reconstructed, and fresh clean ones be secured for breeding in, instead of the old black ones that otherwise would remain as long as the stock could live in the hive.
Guide-combs can also be used with glasses. These may be filled, with great regularity, by adopting the following directions, which, we believe, have never before appeared in print:—
Procure a piece of clean, new, empty, worker honeycomb, which has not had honey in it (because honey will prevent adhesion to the glass); cut it into pieces of about three-quarters of an inch square. Gently warm the exterior of the glass (this we find is best done by holding the glass horizontally for a short time over the flame of a candle); then apply one of the pieces of empty comb inside at the part warmed, taking care, in fixing it, that the pitch or inclination of the cells is upwards—in fact, place the guide-comb in the same relative position that it occupied in the hive or glass from which it was taken. There is some danger of making the glass too warm, which will cause the wax to melt and run down the side, leaving an unsightly appearance on the glass; but a little experience will enable the operator to determine the degree of warmth sufficient to make the comb adhere without any of it being melted. It is hardly necessary to state that only the very whitest combs ought to be used. A short time should be allowed before changing the position of the glass, so that it may cool sufficiently to hold the comb in its place. Six or eight pieces may thus be fixed, so that, when the glass is filled, it will present a star shape, all the combs radiating from the centre. The annexed illustration shows the appearance of a glass as worked by the bees, in which guide-combs were fixed in the manner described above. The drawing was taken from a glass of our own, filled after being thus furnished. In the Old Museum at the Royal Gardens, Kew, may be seen a Taylor's glass, presented by us, some of the combs in which are elongated on the outside to the breadth of six inches.
