SHIPSHAPE STANDS THIS OLD NORTH CHINA VILLAGE, WHOSE DWELLERS HAVE SUCCESSFULLY COMBATTED SOIL WASTAGE To keep out bandits, peasants near Lanchow built their mud walls along the natural lines of the hill's crest, outlining aprow and blunt stern. They have relentlessly resisted erosion by waves of bench terracing. Ridges on the left have started to waste away and, unless vegetation isencouraged along thebanks, theprocess will goon. Here farmers have good wheat crops when rain is plentiful, but seasons of drought bring famine. Sheep tracks furrow thesteep slopes intheforeground.
