Old angling books are fun to read, especially old angling books about fly fishing. I find it quite interesting that much of what we think is new and revolutionary is usually just a rehash of something that was discovered long ago. Recently I have been perusing a small booklet published in 1860 entitled, "The Concise Practical Treatise on Artificial Fly Fishing for Trout," by Grey Drake. The entire booklet is 24 pages long, but it contains many tidbits of angling knowledge that are still as relevant today as they were when they were printed.
