In case the bees do not speedily after swarming manifest signs of settling, a few handfuls of sand or loose mould may be thrown up in the air so as to fall among the winged throng; they mistake this for rain, and then very quickly determine upon settling. Some persons squirt a little water from a garden engine in' order to produce the same effect. There are, indeed, many ingenious devices used by apiarians for decoying the swarms. Mr. Langstroth mentions a plan of stringing dead bees together, and tying a bunch of them on any shrub or low tree upon which it is desirable that they should alight; another plan is, to hang some black woven material near the hives, so that the swarming bees may be led to suppose they see another colony, to which they will hasten to attach themselves. Swarms have a great affinity for each other when they are adrift in the air; but, of course, when the union has been effected, the rival queens have to do battle for supremacy. A more ingenious device than any of the above is by means of a mirror, to flash a reflection of the sun's rays amongst a swarm, which bewilders the bees, and checks their flight. It is manifestly often desirable to use some of these endeavours to induce early settlement, and to prevent, if possible, the bees from clustering in high trees or under the eaves of houses, where it may be difficult to hive them. Should prompt measures not be taken to hive the bees as soon as the cluster is well formed, there is danger of their starting on a second flight; and this is what the apiarian has so much to dread. If the bees set off a second time, it is generally for a long flight, often for miles, so that in such a case it is usually impossible to follow them, and consequently a valuable colony may be irretrievably lost. Too much care cannot be exercised to prevent the sun's rays falling on a swarm when it has once settled. If exposed to heat in this way, bees are very likely to decamp. We have frequently stretched matting or sheeting on poles, so as to intercept the glare, and thus render their temporary position cool and comfortable. Two swarms sometimes depart at the same time, and join together; in such a case, we recommend that they be treated as one, by putting them into a hive as before described, taking care to give abundant room and not to delay affording access to the super hive or glasses. They will settle their own notions of sovereignty by one queen destroying the other. There are means of separating two swarms, if done at the time; but the operation is a formidable one, and does not always repay even those most accustomed to such manipulation.
