A level is set up and a reading of 2.195 m is taken on a bench mark the elevation of which is 89.54 m. At the beginning of the line to be profiled, the rod reading is 2.415 m.; 20 m from the beginning, it is 1.807 m; at 60 m, it is 0.712; at 66 m and 80 m, the rod readings are1.381 m and 0.782 m., respectively. On a rock that is not on line, the rod reading is 0.555 m. The level is then removed ahead, set up and a rod reading of 1.952 m is observe, the rod still being held on the rock. The readings along the profile are then resumed: 100 m from the beginning of the line, the rod reading is 1.159 m; 140 m from the beginning of the line rod reading is 1.434 m; finally, 180 m from the beginning of the line the rod reading is 2.196 m. From following description above make a complete form of profile level notes
