One who splits [wood from] an olive tree may not cover [the cut] with dirt, but he may cover it with stones or straw. One who cuts beams of sycamore may not cover [the cut] with dirt, but he may cover it with stones or straw. One may not cut down a virgin sycamore in the seventh [year], because it is a labor. R’ Yehudah says: In the [regular] way, it is forbidden; rather, he should raise [the cut above] ten handbreadths, or raze it at the ground.
