It is composed of a frame provided with a sheet of perforated metal, with a bee-space above and below, and placed between the two stories. This perforated metal was, as far as we knew, first recommended by a Lorrainer cure, Collin, about the middle of the past century. The perforations are of such size that the worker bees can pass through them, but neither the queen nor the drones can get through, owing to the greater size of their corslet or thorax. The first queen-excluders made were objectionable, con- stituting a very serious obstacle to the free passage of the bees and of ventilation. Ventilation is very important, as the bees, in the summer months, are very numerous in the hive. They need pure air as we do, and their great numbers increase the temperature of the hive to the danger point, unless they can force air up through the hive and out again, so as to keep the temperature below the dan- ger point, or about blood Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Dadant, C.
