From Graces Guide

681. RICKMAN, WILLIAM CHARLES, 21 Park Side, Hyde Park Corner, and Pole Hore, Wexford — Inventor and Designer.

Road level: two varieties of an instrument for use in agriculture, drainage, and other purposes. This instrument enables a person unacquainted with the practice of levelling, and without calculation, or the aid of an assistant, to know the level of the ground, and also its rise or its fall. Only one observation is necessary, and the result is then found stated upon the dial. J. Peirce, maker, Wexford.
