On the 26th of June 1826, I suffered a colony of Bees to swarm, in order to prove the truth of the foregoing statements. It was a very fine colony: the thermometer had been standing at 110 for six days previously, in one of the collateral end-boxes; on the eighth day it rose suddenly to 120. I was then forcing my Bees to leave their home; I could have lowered their temperature, and by so doing, I could have retained my worthies in their native boxes: but I was then about to prove a fact of the greatest moment to apiarians. On the ninth day, at half-past twelve o'clock, the finest swarm I ever beheld towered above my head, and literally darkened the atmosphere in the front of my apiary. After remaining about five minutes in the open air, the Queen perched herself upon a tree in my garden, where she was exposed to the rays of a scorching sun; but her loyal subjects quickly surrounded her, and screened her from its influence. I immediately did what I could to assist my grand prize, by hanging a sheet before it, to ward off the intense heat of the sun. I allowed the Bees to hang in this situation until the evening. During the absence of the swarm from the colony, my full employment was to watch the parent-stock, in order that I might, in the evening, return the Bees of this beautiful swarm to their native-hive, which they had been forced to leave. Curiosity and a desire to solve a doubtful problem, for the good of future apiarians, led me to act as already related, at the expense of much inconvenience to the Bees. The remaining Honey-Bees continued labouring during the remainder of the day; and in the evening of that same day, the thermometer was standing at 90 degrees in the old stock; so that the absence of the swarm had lowered the temperature of the pavilion 30 degrees, and I was quite sure I could reduce it in the collateral end-box to that of the exterior atmosphere, which, after the sun had gone down, was only 65.
