Comment:
The tide gauge (see hdl:10013/epic.31312.d001 for the construction plan) is a wooden frame-work standing on the ice over the hole H. A Line, L, passes from the 200 pound anchor through the hole H over pulleys PP, and terminates at the counterpoise C; this counterpoise weighing about 20 pounds. A fixed wooden scale, S, attached to the frame of the gauge, was subdivided to feet and tenths and hundredths, and to the line was attached an index which, moving along the scale, gave readings showing the stage of the tide.
The zero of the scale was placed low down, and the numbers increased upward and downward from this zero. the numbers above zero were considered positive (+) and those below it negative (-). When the tide rose, the ice, the gauge, and all its appurtenances were lifted up, and in such manner that the difference between any two index readings would indicate the change of level between the readings. From the construction, as well as from observations, therefore, we see that increasing numbers indicate rising tide and diminishing numbers falling tide.
