Your article “The Botanic Age” gives welcome space to the subject of pre-Stone Age advances. It would seem important to also mention the Bamboo Age. Bamboo is nature’s fast growing construction material and it can be modified to make anything from a knife to a source of ignition, cooking pot or twisted thread. It is also a lightweight but structurally supreme material to build a raft, boat or major construction (9 November, p 32).
