Pinterest • The world’s catalogue of ideas

In this "artful, informative, and delightful" (William H. McNeill, New York Review of Books) book, Jared Diamond convincingly argues that geographical and environmental factors shaped the modern world. Societies that had had a head start in food production advanced beyond the hunter-gatherer stage, and then developed religion --as well as nasty germs and potent weapons of war --and adventured on sea and land to conquer and decimate preliterate cultures.

Cor-ten edging

Cor-ten steel is a beautiful material. It is being used in gardens more and more and loved for its warm, weathered and industrial look. In my experience, this edging looks better when it is 1/4" thickness. Anything thinner and you will see bowing and the edge will not appear clean and straight, which is it's best attribute. Also when specifying corten, make sure you get a certificate that verifies it is truly cor-ten, and ASTM grade A588 or A606. View Product Website
