Uploaded by: Tracy_Alley On: Jun 24 2006, 05:48 AM Views: 1075 · Comments: 0
Peter Ray is a retired professor from Standford University. He taught college courses for forty-seven years so he has a wealth of knowledge to share. In this picture, he is analyzing cross sections of shrub branches to discover their age. He has great patience when slicing sections off of shrub branches. It takes great precision. Peter is married to Syndonia Bret-Harte.
