R. Radau, Popular Science Monthly (1873)
“ A house, just like the clothes we wear, is, first of all, a shelter to protect us against the medium around us, and to shield us against the inclemency of the seasons. The animal, in this happier than man, has no need of dress—Nature supplying it with plumage or with fur—but yet is required to build for itself the dwelling-place where it is to find shelter. May we suppose that here, too, Nature provides for every thing, and that blind instinct guides the bee in the construction of her cell, and the bird in the building of its nest? ”
