Gave it to him and he loves it. Four stars on first, fairly brief, look-through, pending a possible fifth star once we've settled as he plans to actually use some of the instructions. I do love when useful books go out of copyright and get reprinted so that they're more easily found. The depth and breadth of "devices" explained in this...astounding. Lots of farm tricks that we've used in the past (keeping a gate from sagging, for example), lots of simple and inexpensive ones that we'll be using in the future. Full instructions for a cinder block house! Great. He's very happy. Tucked it into a pocket and plans to flip through it in camp during this current hunting trip.
