If you grew up hunting, fishing, and camping this is worthless. If you don't know how to hunt or fish, it will be worse for you. (Lots of one sentence 5 star reviews makes me doubt these are legitimate reviews.) Who feels strongly enough about a book to write a review and then can only muster up one sentence? This book simply does not have enough detail for anyone. Each section is a few paragraphs.Here is the full advice on how to catch game birds without a gun:
"grouse promise feasts for anybody lost in the wilderness, especially as a few stones or sticks are often the only weapons needed to catch one. If one misses the first time, such foul usually will afford a second or even third chance to be captured."
Now you know that you can apparently kill a grouse by throwing a stone at it. I grew up hunting grouse and you won't see one until you flush it out and it is flying away. You could try 1000 times and still not hit one with a stone. Even if you could get within 10 feet of a stationary target like a rabbit, it's unlikely you could throw a stone hard enough and accurately enough to hit it.
The section on snares is more useful, but again, lacking in useful detail.
