Also, in gunnery, the throw of the shot.--_To pitch_, to plant or set, as tents, pavements, pitched battles, &c.
PITCH-BOAT. A vessel fitted for boiling pitch in, which should be veered astern of the one being caulked.

PITCH IN, TO. To set to work earnestly; to beat a person violently. (A colloquialism.)

PLAIN. A term used in contradistinction to mountain, though far from implying a level surface, and it may be either elevated or low.
PLAN. The area or imaginary surface defined by, or within any described lines. In ship-building, the _plan of elevation_, commonly called the _sheer-draught_, is a side-plan of the ship. (_See_ HORIZONTAL PLAN and BODY-PLAN, or plan of projection.)
PLANE. In a general sense, a perfectly level surface; but it is a term used by shipwrights, implying the area or imaginary surface contained within any particular outlines, as the plane of elevation, or sheer-draught, &c.
PLANE-CHART. One constructed on the supposition of the earth"s being an extended plane, and therefore but little in request.
PLANE OF THE MERIDIAN. _See_ MERIDIAN.
PLANE-SAILING. That part of navigation which treats a ship"s course as an angle, and the distance, difference of lat.i.tude, and easting or westing, as the sides of a right-angled triangle. The easting or westing is called departure. To convert this into difference of longitude, parallel, middle lat.i.tude, or Mercator"s sailing is needed, depending on circ.u.mstances.

Also, in long voyages or tedious blockades, play-acting may be encouraged with benefit; for the excitement and employment thus afforded are not only good anti-s...o...b..tics, but also promoters of content and good fellowship: in such--
