Water Heater and Food Cooker
Take a barrel, an iron tube about three inches in diameter and perhaps ten feet long, and a wooden plug. Have thread cut in one end of pipe; screw it into right-size hole in barrel, four inches from bottom. Drive plug into outer end of pipe. Put water into barrel. Build fire under pipe (dig trench for fire, if necessary). Can have scalding water in about one-half hour. When cooking feed, it is desirable to have a piece of wire fly-netting fastened over the inside end of the tube.
