为了验证所报道的南安普敦潮汐的特殊性，我于 1842 年 2 月提议前往那里，以便亲眼检查一次或多次潮汐期间海水的涨落。然而，当我的目的被三角测量主任科尔比上校和南安普敦军械地图办公室驻地官员约兰德中尉告知后，我收到了这些先生的提议，为我服务，皇家工兵和矿工军团的士官和列兵，以及准备和确定英尺和矿工的垂直比例尺。英寸，并密切关注观察到的时间的总体准确性。我非常高兴能利用这个机会，因为我相信，没有比三角测量中雇用的工兵更聪明、更忠诚的人了。我很清楚在这种乏味的事情上雇用一组常驻人员驻扎在现场的好处。南安普敦码头末端附近固定着一块垂直刻度的标尺，上面标有刻度和数字，非常靠近码头北侧的登岸楼梯，这样站在楼梯上的人就可以在潮汐的各个阶段（在夜间灯笼的帮助下）轻松阅读刻度。刻度尺的刻度顺序从下往上递增，通过调平，发现刻度尺的零与某些固定标记具有以下关系：
With the view of verifying the reported peculiarity in the tides at Southampton, I had proposed in the month of February 1842 to proceed thither for the purpose of examining, with my own eyes, the rise and fall of the water during one or more tides. As soon, however, as my purpose was made known to Colonel Colby, R. E., Director of the Trigonometrical Survey, and to Lieutenant Yolland, R. E., the Resident Officer at the Ordnance Map Office, Southampton, I received from those gentlemen the offer of placing at my service, for these observations, non-commissioned officers and privates of the corps of Royal Sappers and Miners, as well as of preparing and fixing the vertical scale of feet and inches, and of keeping a watch upon the general accuracy of the observed times. I was extremely glad to avail myself of this offer, for I believe that a more intelligent and faithful body of men does not exist than the Sappers employed in the Trigonometrical Survey; and I knew well the advantage of employing, upon a tedious business like this, a set of regular-service men stationed on the spot. A vertical scale of deal laths, upon which the divisions and figures were branded, was fixed near the end of the pier at Southampton, very near to the landing-stairs on the north side of the pier, so that the divisions could at all stages of the tide (with the assistance of a lantern at night) be easily read by a person standing on the stairs. The order of the graduations of the scale was increasing from the bottom upwards, and the zero of the scale was found, by levelling, to bear the following relation to certain fixed marks:—
