This hive is well adapted for those persons who are desirous of having the opportunity of closely examining the workmanship of the industrious and interesting inmates. It is particularly intended for a window recess or an indoor apiary, and will also be found an interesting addition to the greenhouse. Bees cease to appear disturbed when exposure to the light is continuous, and this discovery enables the bee-keeper to obtain a full inspection. The hive should be screened from the direct rays of the sun, which would worry the inmates, and be otherwise prejudicial. An aperture should be cut in the sash corresponding with the entrance to the hive, through which the bees may find egress and ingress, without being able to gain access to the apartment, as described under the "Ladies' Observatory Hive" (page 120). As the hive is now made to revolve on a wheel like the preceding, this passage must extend eighteen inches within the room to enable the revolution to be made clear of the window. The passage may be glazed over. The process of stocking is identical with that in the last section. Although this hive is constructed of double glass, to keep up a more uniform degree of warmth, still, from the cold nature of that material, and the close contact into which the bees are brought with it, it is advisable to place flannel against it on the outside. Such precaution is found essential if the bees remain in this hive during winter, and very much adds to their comfort on cold nights at most periods of the year. In the daytime, in summer months, the hive being of double glass, the whole may be fully exposed to view, and if the temperature of the apartment in which it stands be kept up to 60 degrees, this extra care will not be needed.
