Tom Brown, Jr., "Field Guide: Nature Observation and Tracking," 1983, about 250 pages. About one-third on awareness and observation technique, including stalking and camouflage; and two-thirds on tracking technique, including pressure releases. Laced with Mr. Brown's beliefs on spirit-in-nature. Filtering out the belief system I found a great deal of useful and interesting information.

I will do a separate commentary on this book along with the three other Tom Brown, Jr. books I read a bit later.
