On the Water

Whalebone Ruler

“Straight edges” or rulers were used aboard ships as writing guides on the unlined pages of letters, journals and logbooks. The back side of this long stick is marked in 2-1/4, 4-1/2 and 9-inch sections, indicating another usage, probably by the ship’s cooper to measure the level of liquid (water, wine, beer or whale oil) in his wooden casks.
