Get a RAGING INFERNO going with anything - newspaper, pine cones, etc. Then pack your fuel - sawdust, pine needles, burlap, baling twine, sumac seed heads, or whatever - on top of that. When you think you have enough, put some more in. Then finally top it off with a handful of green grass. Mine stays lit for hours. I keep it in a galvanized bucket with more grass stuffed in the spout if I'm driving between bee yards.
