The use of a pulley will greatly facilitate well construction work. If unavailable, arrange a cross piece with a smooth surface over which you can pull the rope. It is far more preferable to pull the rope over a pulley than try to stand at the well edge and pull the rope straight up hand over hand. Ropes will wear much faster when pulled over even a relatively smooth surface than when a pulley is used and should therefore be checked frequently.
