The harpooner made a ‘pitchpole’ dart: that is he hurled his weapon into the air where it described a fine curve and fell point downward on the animal’s back just as he was disappearing.Herman Melville also describes pitch-poling in Chapter 84 of Moby Dick. The falling part of the curve is well-described by Kipling at p. 136 line 24:

'Seamen are now agreed that a "knot" is a unit of speed, viz., one nautical mile per hour, and that "knots an hour" is therefore a gross error.
