If the swarm should rise in the full heat of the day, and the sun shine hot upon them, they will not continue long in their first situation; for when they find they have all got their company together, they will soon uncluster, rise again, fly to some particular spot which has been fixed upon for that purpose by detached parties of bees, who return and acquaint the swarm; therefore I would advise to hive them as soon as possible, and remove them in the evening to the place where they are to remain.
The supposed relative value of early and late swarms is thus mentioned in an old English proverb:—
A swarm in May,
Is worth a load of hay.
A swarm in June,
Is worth a silver spoon;
A swarm in July,
Is not worth a fly.
