This July 4, 2011 photo shows Levern Halstead, right, as he helps Chrisnet Excellus, center, a school principal in Seguin, use a power saw to cut planks for one-room wooden houses they helped build in the village of Maplat, Haiti. Most villagers in Maplat haven’t been trained on how to use power tools because only a few have electricity. Halstead, who runs Farsight Christian Mission from his home outside Chattanooga, Tenn., says that his trips must have an objectively measurable result _ a new building, a new bridge, a new well.
