Answer 2

Method

At the point chosen for all the experiments the river was a slow-flowing drainage canal running in uninterrupted straight line for a six-mile stretch to the north-east of the village of Welney. The most famous of the observations, and the one that was taught in schools until photographs of the Earth from space became available, involved a set of three poles fixed at equal height above water level along this length. As the surface of the water was understood to follow any hypothetical curvature of the Earth, the observation that the three poles aligned perfectly when observed through a theodolite serves as evidence of a flat Earth.
