Folks, a good, basic book is Camp Cookery by Horace Kephart. He went into the Smoky Mountains to live, and camp, long before Hudson Trail, LL Bean, Abercrombe and Fitch, and the Boy Scouts. He not only shows how to apply simple equipment in mutiple ways (campers of his period had to improvise), but he also has a good section on food values vs. weight, warm vs cold weather rations, and food needs in the woods vs. in settled areas. There is an excellent baking section, and he speaks of earth ovens (not to be confused with clay ovens), reflector ovens, and improved baking of all types without ovens.
The book was published in 1910, though it's based on many years experience leading up to the publishing date. The body of the work is also found in his book Camping and Woodcraft, so if you want a very good book on all phases of living in the wilds, omit Camp Cookery, and just get the latter. As it was the time of self improvisation as the "camping-fad" was in full swing, there are lots of do it yourself type ideas in Camping and Woodcraft.
