Clinometers

When measuring up or down a slope, long distances could be measured in parts with the chain held level, or the full length of the chain could be used with the slope distance measured with an Abney or Locke pocket level clinometer. Knowing the slope of the chain enabled the horizontal distance to be determined. For small inclines, the correction was usually obtained from a slope correction table.
