This Line Means Repose.
It is the position a person assumes in sleep; it is the surface of the ocean during a calm (Fig. 236).
Here we again have the upright line AB (of Fig. 220), in the mast of the becalmed and immovable ship of Fig. 236. When a squall comes up not only does AB change to a diagonal line (Fig. 237), but the horizontal line, indicating repose, is broken into a series of irregular points, showing noise, movement, and commotion. Figs. 238 and 239 show the same effect of lines.
