is directly proportional to the weight of the body attached to the
hook B, the divisions of the scale will all be equal. It will thus be
seen that the apparatus is extremely simple in theory, and it only
remains to construct it in such a form that the mercury may not easily
be spilt in moving the instrument from place to place. This is
effected by causing the cross head E to fill the tube while working
freely therein, and a small valve is arranged to allow for the passage
of air. The cross bar G can be regulated upon the rods by means of set
screws.--_Industries._

REEFING SAILS FROM THE DECK.


While this method may be applied to topsails and top-gallant-sails, I
especially apply it to courses, which, being so difficult to reef the
old way, may by this method be reefed from the deck in a few minutes.

After several years of trial by myself and others, on voyages around
Cape Horn under all circumstances of weather, of sleet and snow, this
method has always given the utmost satisfaction.

The average time required for reefing and setting was noted for five
years, being seven and one-half minutes.
