This afternoon when I finished my teaching task I observed a skilled peasant earthing up the potatoes in the traditional way with great interest for the potato plot is just in front of the windows of our office in the school yard. He did the work with two head of cattle drawing the plow under his control. The two tamed cows walked slowly along the right furrows without treading on the plants. The farmer is in his seventies, small but strong. He told me the cattle only obeyed his orders. His son had ever tried several times to manage them but ended in failure.
