Book 8: Chapter 4 Analysis

Sir Isaac's plan was a clever way to discover who bought the urine and where chemical was manufactured into phosphorous. Marsh agrees to allow a hidden man to record distance from within a sack concealed on his cart. Therefore, while he negotiates sale of the urine and is blindfolded and taken to an undisclosed location, another person records their whereabouts using Sir Isaac's methods. Now the club can pinpoint the exact location by counting the number of wheel rotations on the cart and recording noises. The concept was simple but effective.
