Too Long; Didn't Read

The Pelopæus gives us a very poor idea of her intellect when she plasters the spot in the wall where the nest which I have removed used to stand, when she persists in cramming her cell with Spiders for the benefit of an egg no longer there and when she dutifully closes a cell which my tweezers, extracting both germ and provisions, have left empty. The Mason-bees, the caterpillar of the Great Peacock Moth and many others, when subjected to similar tests, are guilty of the same illogical behaviour: they continue, in the normal order, their series of industrious actions, though an accident has now rendered these useless. Just like mill-stones, which do not cease revolving though there be no corn left to grind, let them once be given the compelling power and they will continue to perform their task despite its futility. Are they then machines? Far be it from me to think anything so foolish.
