"Go first to your old plant and watch carefully the watercourse made by the rain. By now the rain must have carried the seeds far astray. Watch the crevices made by the runoff, and from them determine the direction of the flow. Then find the plant that is growing at the farthest point from your plant. All the devil's weed plants that are growing in between are yours. Later, as they seed, you can extend the size of your territory by following the watercourse from each plant along the way."
