Surveyors' wheel (detail)
A surveyors' wheel, also known as a waywiser, was used for measuring distances along the ground. This is a detail of a wooden example made around 1800, probably by Jeremiah and Walter Watkins, scientific instrument makers based in London. The detail shows the instrument's dial.
The dial has two revolving hands which move as the outer wheel revolves and is graduated in yards, poles, furlongs, miles, links and chains. It is signed 'J. & W. Watkins,/Charing Cross/London'.
The instrument records the distance travelled by the number of revolutions made by the circumference of the wheel in the course of a journey. It was used particularly for measuring the distance along roads.
