Figure 2 shows the upper glass-frame of this hive with two small circular openings through the top of each arm, over which openings are placed small glasses, (at e. e.) in both Figures, for receptacles for honey, and are intended to answer the same purpose as those do which are placed upon the inverted-hive. A line drawn from one extremity of any one of these arms or wings, to the extremity of the arm or wing directly opposite to it, is twenty-three inches; and the distance between the dotted lines, which are intended to mark the glass-way, or, in joiners' phrase, the _rebate_ to receive the edges of the glass, is exactly one inch and three-fourths. The lower glass-frame, which (in Fig. 1) is placed upon f. the shaft of the pedestal already described, is the exact counterpart of the upper frame, with the exception of its not having any perforations for honey-glasses: the only perforation in this frame is that at its centre; which must be made to correspond with that of the shaft, and be a continuation of the Bee-passage into the hive. These two frames are connected and made one by four upright pieces, or ends, (marked a. b. c. d. in Fig. 1,) these upright, end-pieces must be rebated, or channeled, to receive the ends of the glass-plates. Eight squares of glass, each ten inches and a half by ten inches, fastened with putty into this frame-work,--that is, two squares into each wing, will complete the glass-hive; which, when placed upon the top of the pedestal, and made steady by an axis fixed at the central point of the upper frame, and turning in a socket under the ball, constitutes _an observatory-hive_. Confined as is the space between the glass-plates in each wing, they being but an inch and three-fourths apart, there is, nevertheless, room enough for the construction of one comb; and space for more than one comb would spoil it as an observatory-hive: and, though each wing may appear to be but small, there are upwards of 760 cubic inches of clear space in the hive. It is so constructed that plenty of light and the utmost transparency are afforded for observing and minutely examining the Bees and the works of the Bees in all their stages. Indeed the grand object of this contrivance is--to expose to view the labours of the Bees in the inside of their hive; and as the machine may be moved round at pleasure, not a Bee can enter it, without being observed, nor can a single cell be constructed in secret. I will only add--that the appearance of the Bees in this hive is beautiful, and excites admiration and surprise,--nay, is capable of enlivening the drooping spirits of the most desponding apiarian; for who can view the Queen of the hive constantly laying her eggs, and, by so doing, constantly propagating her species, and her thousands of loyal subjects, whose indefatigable labour in all its parts is so conspicuous, without experiencing sensations of the purest pleasure,--nay, more of gratitude to God for his goodness to man!
