Excellent book by trapping legend Charles Dobbins. This is not a method book, rather it describes in great detail how to determine both the limits and capabilities of lures, baits, and urines. It doesn’t explain how to make lures or baits, but deals with testing lures, baits, and urines for effectiveness. Tells you how often to re-lure, and will help you determine which lures work best on your own trapline. You will know how far a certain lure will bring the target animal under different weather conditions. 110 pages.
