A third discovered their flight and attempted a race, but like the others soon came out behind. The before-mentioned neighbor saw them, and thought of the fresh earth that he had ploughed up, which he threw among them till they stopped. How much farther they would have gone, if any, would be guessing. That it was the same swarm that started three miles away, appears almost certain; the direction was the same as seen by all, until they were stopped; the time in the day also exactly corresponded. We will now return to the issuing of the swarms. There will be some emergencies to provide for, and some exceptions to notice. TWO OR MORE SWARMS LIABLE TO UNITE. If we expect to keep many stocks, the chances are that two or more may issue at one time; and when they do, they nearly always cluster together (I once knew an instance where only three stocks were kept; they all swarmed and clustered together). It is plain that the greater the number of stocks, the more such chances are multiplied. DISADVANTAGE. One first swarm, if of the usual size, will contain bees enough for profit, yet two such will work together without quarrelling, and will store about one-third more than either would alone; that is, if each single swarm would get 50 lbs., the two together would not get over 70 lbs., perhaps less. Here, then, is a loss of 30 lbs., besides one of the swarms is about lost for another year; because such double swarms are not generally any better the next spring as a stock, and often not as good as a single one. You will therefore see the advantage of keeping the first swarms separate. CAN OFTEN BE PREVENTED. "Prevention is better than cure." We can, if we keep a good lookout, often prevent more than one issuing at a time. This depends on our knowledge of indications, in a great measure. I have said that before starting to fly off, they were about the entrance in great numbers; there may be one exception in twenty, where the first indications will be a column of bees rushing from the hive. To take this matter a little farther from the surface, we will take a peep at the interior; that is, if our hives contain glass boxes, such as have been recommended. It is an advantage to know which are about to cast their swarms, as long beforehand as possible. INDICATIONS OF SWARMING INSIDE THE HIVE.
