'The world is one vast garden, bringing forth crops of the most 

 luxuriant and varied kind, century after century, and millennium 

 after millennium. Yet the face of Nature is nowhere furrowed by 

 the plough, no harrow disintegrates the clods, no lime and phos- 

 phates are strewn upon its fields, no visible tillage of the soil 

 improves the work on the great •world's farm.'
