Of this adherence to life, advantage has been taken at the time of deprivation,--recourse having been had to immersion for removing a portion of the combs, the bees were afterwards spread on a cloth in the sun, and became reanimated. Dr. Derham says that he has known bees revive after remaining twenty-four hours under an exhausted air-pump. After long submersion the proboscis of the bee is generally unfolded, and stretched to its full length. The first symptom of returning animation, is a motion at its extremity, succeeded by a similar motion at the extremities of the legs. Having so far progressed towards recovery, the tongue is soon folded up again, and the bee prepared to resume its customary occupations. _Moths_ and _spiders_ should be watched and destroyed in an evening, as at that time the former are hovering about, and the latter laying their snares; at that time too there would be less danger of annoying the bees, or of being annoyed by them. Wherever moths have gained possession of a hive, it is always necessary to destroy the bees, or to drive them into another hive. Attention to the following particulars may guard the bees from many of their enemies. A frequent cleaning of the hive floors; the use of new or well cleaned hives; the timely renewal of the coverings, and keeping the ground bare around the apiary, particularly in front of it. This last precaution may also prevent the entanglement of the bees in rubbish or long straggling vegetables, should they on their return home fall down through fatigue or the weight of their loads. From _rats_ and _mice_ the surest safeguard is an appropriate position of the hives; traps may also be laid, and in winter the entrances into the hives contracted. It will be prudent likewise to case the legs of the bee-benches with tin. Bees in a healthy vigorous state will attack and kill an intruding mouse; but in winter it might commit great depredations, and cause the emigration of the bees on the return of warm weather. (Mr. Espinasse says that he has known a mouse take up his winter quarters in a hive, without destroying the bees.)
