为了证实所报道的南安普敦潮汐的特殊性，我在1842年2月提议去那里，以便亲眼看看一次或几次潮汐期间水的涨落情况。然而，当我的目的一被告知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干事约兰德中尉，我就收到了这些先生的邀请，请他们为我服务，为这些观测服务，并准备和安装英尺和英寸的垂直刻度，并密切关注所观测时间的总体精度。我非常高兴能得到这份工作，因为我相信，世界上再也没有比三角测量局雇用的那些勤杂工更聪明、更忠诚的人了；我也深知，在这样一项繁琐的工作中，雇用一批驻扎在现场的正规军是有好处的。在南安普敦码头的尽头附近，离码头北侧的登岸楼梯很近的地方，固定了一块竖直的板条，上面刻着部门和数字，这样站在楼梯上的人就可以很容易地读到潮汐各个阶段的部门(晚上在灯笼的帮助下)。刻度的顺序是从下到上递增的，通过水平调整，刻度的零点与某些固定标记具有如下关系：
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:—
