"Don't you wear a veil for this sort of job?"
As a rule Elizabeth did. She had reached a stage of intimacy with her bees which rendered a veil a superfluous precaution, but until today she had never abandoned it. Her view of the matter was that, though the inhabitants of the hives were familiar and friendly with her by this time and recognized that she came among them without hostile intent, it might well happen that among so many thousands there might be one slow-witted enough and obtuse enough not to have grasped this fact. And in such an event a veil was better than any amount of explanations, for you cannot stick to pure reasons when quarrelling with bees.
