Originally published by The Derrydale Press in 1938 as a companion to Walden's Big Stony , Upstream and Down is a distillation of the author's ideas about fishing during a fishing career spanning more than 30 years. Walden's musings on the "great angling fraternity" and its different "members": Barefoot Boy, Old Timer, the Artists and Scientists, the Purist, Hogs, "Noblesse Oblige", and finally She who goes Astream, are delightful. His personal memoirs and thoughts on fishing make for a book that is informative, practical and a pleasure to read.
