It was the big central taproot which baffled them. They had hewed easily through the great side roots, large as branches, covered with soft brown bark; they had dug down and cut through the forest of tender small roots below; but when they had passed the main body of the stump and worked under it, they found that their hole around the trunk was t large eugh in diameter to enable them to reach to the taproot and cut through it. They could only reach it feebly with the hatchet, fraying it, but there was chance for a free swing to sever the tough wood. Instead of widening the hole at once, they kept laboring at the root, working the stump back and forth, as though they hoped to crystallize that stubborn taproot and snap it like a wire. Still it held and defied them. They laid hold of it together and tugged with a grunt; something tore beneath that effort, but the stump held, and upward progress ceased.
