How to Survival in the outdoors Book

I plan on learning all I can from this book. Some of the shelters and ways to survival out in the bush with not enough supplies. I also, am going to learn how to start a fire with out any matches. Learning how to tie the knots that will hold all of the different types of shelters I want to build will be the hardest. I plan on trying to build this type of shelter but with a wall in the front to reflect the fire heat back into it.
