Из знаменитого руководства американского пчеловода Лангстрота, середина 19-го века:
Notched and ragged wings, instead of gray hairs and wrinkled faces, are the signs of old age in the bee, and indicate that its season of toil will soon be over. They appear to die rather suddenly, and often spend their last days, and sometimes even their last hours, in useful labors. Place yourself before a hive, and see the indefatigable energy of these aged veterans, toiling along with their heavy burdens, side by side with their more youthful compeers, and then say if you can, that you have done work enough, and that you will give yourself up to slothful indulgence, while the ability for useful labor still remains. Let the cheerful hum of their industrious old age inspire you with better resolutions, and teach you how much nobler it is to meet death in the path of duty, striving still, as you "have opportunity," to "do good unto all men."
