Smoke: 



During all these experiments it was absolutely necessary to refrain from smok- 

 ing tobacco because the least smoke in the laboratory invariably excited the 

 bees. They produced an uproar by rapidly vibrating their wings, became very 

 restless, and remained in this unquiet state for some time after being irritated. 

 The least amount of smoke from a bee keeper's smoker, whether inside or near 

 the outside of the house, also usually excited them.
