Wow, most of what I find on FB is trash, but here's a real gem.
Free, downloadable PDF books from Pioneers in the 1880's.
A great read for the historian, self-sufficient guru, or closet prepper. . . .
Pioneer Handbooks
Looks like they cover loads of topics from gardening, soap making, herbal medicine, orchards, livestock, dairy, hunting, recipes, cleaning, carpentry, to 1889 plumbing , etc
