"Having had a complete set of Mr. Nutt's boxes presented to me, I, though comparatively a novice in apiarian science, and not at that time particularly attached to it, could not, in compliment to the donor, do less than endeavour to work them, that was--get them stocked. That was done with a swarm on the 18th of May 1830; and the middle-box, or pavilion of nature, as Mr. Nutt calls it, into which the said swarm was taken just in the same way it would have been if put into a common straw-hive, was conveyed a distance of nearly four miles and placed in my garden in the evening of the same day. The next day being fine, I observed that the Bees were very busy constructing comb, and had, within twenty-four hours of their being domiciled in their new abode, actually made a progress in that most curious work that astonished me: they were passing and re-passing, and literally all alive; many were visibly loaded with materials for their ingenious work. My curiosity was excited, and so much was I pleased with my multitudinous labourers that I visited them daily, and many times in the course of each day, when the weather was favourable for their getting abroad. Their combs were rapidly advanced; but to my great mortification they very soon obstructed my view of their interior works, by bringing a fine comb quite over the only little window at the back of the pavilion, at the distance of about half an inch from the glass. I was not, however, without the means of ascertaining that they were filling the pavilion with their treasures, and consequently that they would soon be in want of more room. I, therefore, at the end of a fortnight admitted them into the large bell-glass by withdrawing the slide, which, when closed, cuts oft' the communication between the pavilion and the said glass. They (the Bees) immediately reconnoitred it, as it were, and examined it round and round, and presently took possession of it in great numbers; and in the course of the second day afterwards I could perceive that they began to continue their work upwards from and upon the combs in the box. Here I was again inexpressibly gratified by daily observing the progress of their beautiful work, and by the busy thousands in perpetual motion. When they had about half-filled the glass, and before I was aware that there was any occasion for their admission into either of the collateral-boxes, they suddenly threw off a swarm. That event I attribute partly to my own inexperience in apiarian matters, and partly--principally to the want of a thermometer by which to ascertain and regulate the temperature of the crowded pavilion, so as to keep the Bees _at the working, and below the swarming point of heat_. Mr. Nutt assures me that a barn would not contain a colony of Bees if its temperature were raised above a certain degree. What that precise degree of heat is I leave to Mr. Nutt to determine and explain: at present it is enough to state that I am convinced it is possible, nay, quite
