HOW TO USE TRANSITS & LEVELS

THE OPTICAL LEVEL (SOMETIMES CALLED THE DUMPY LEVEL) WHICH HAS ITS TELESCOPE FIXED IN A HORIZONTAL POSITION, AND THE TRANSIT-LEVEL, WHICH TURNS NOT ONLY SIDEWAYS, BUT ALSO UP AND DOWN IS DESCRIBED. THE TRANSIT LEVEL ENABLES DETERMINATION OF PLUMBNESS OF A WALL AND ALSO ALLOWS MEASUREMENT OF VERTICAL ANGLES AND RUNNING STRAIGHT LINES. THE OPTICAL LEVEL CONSISTS OF A TELESCOPE, LEVELING SCREWS, THE VIAL OR BUBBLE AND A THREE HUNDRED SIXTY-DEGREE SCALE. AN EXAMPLE IS GIVEN OF HOW TO ESTABLISH THE FOUNDATION CORNERS OF A HOUSE. EITHER THE OPTICAL OR THE TRANSIT-LEVEL MAY PROVE TO BE THE MOST USEFUL OF THE CONTRACTOR'S TOOLS, AND IS WORTH THE TIME REQUIRED TO MASTER THE TECHNIQUES.
