An hour later we again hove the old-fashioned log and checked our reading on the patent log. For the information of landsmen, it may be well to say that a knot on the log line--and here is where the term comes from--is a distance of forty-seven feet, four inches (for a 28-second glass), the same proportional part of a sea mile or

of 6,080 feet that 28 seconds is of an hour. The different knots along the line are distinguished by fish line tucked into the strands and a knot cast for each mark away from the start. Tenths are estimated, the length between knots being divided by shreds of white bunting into five parts. If sailing fast, as we were, a _short glass_ is sometimes used; this registers fourteen seconds and the readings on the log line must be doubled. In passing it may be well to mention that the old-fashioned log chip, where speeds are not over, say fifteen knots, is the most reliable method of measurement of rate of speed through the roster ever devised. Also, the fact that the sea mile or
