"The tradition of John Burroughs, which you seek to keep alive through these awards, is a long and honorable one. It is a tradition that had its beginnings in even earlier writings. On the other side of the Atlantic it flowered most fully in the works of Richard Jefferies and W. H. Hudson; and in this country the pen of Thoreau - as that of John Burroughs himself-most truly represented the contemplative observer of the world about us. These four, I think, were the great masters. To those of us who have come later, there can scarcely be any greater honor than to be compared to one of them. Yet if we are true to the spirit of John Burroughs, or of Jefferies or Hudson or Thoreau, we are not imitators of them but-as they themselves were - we are pioneers in new areas of thought and knowledge. If we are true to them, we are the creators of a new type of literature as representative of our own day as was their own."
