In many practical opera- tions, bees may be shaken down from their combs in J3WI/V Fig. 31.—Longitudinal Section through Thorax of Drone (Magnified Seven times).

The utility, beyond the purposes of flight, of filling up with air, and the method of its accomplishment, are both interesting and curious. Fig. 31 gives a section through the thorax of the drone, showing the muscles of flight, surrounded on all sides by air sacs (as), from which pass very numerous tracheae (page 42), supply- ing the abundant oxygen these most active muscles re-
