When the wind crosses a ship’s course, either directly or obliquely, that side of the ship upon which it acts is termed the _weather_ side; and the opposite one, which is then pressed downwards, is termed the _lee_ side; all on one side of her is accordingly called to windward, and all on the opposite side to leeward: hence also are derived the _lee_ cannon, the _lee_ braces, _weather_ braces, &c. PAGE 66, l. 24; and PAGE 67, l. 2. _Topsails, reef, blocks._ _Topsails_ are large square sails, of the second magnitude and height; as the _courses_ are of the first magnitude, and the lowest.—_Reefs_ are certain divisions of the sail, which are taken in or let out in proportion to the increase or diminution of the wind. _Blocks_ are what landsmen would rather term, from the French word, (_poulie_) _pullies_. PAGE 67, l. 15, 16, 19. _Halyards—bow-lines—clue-lines—reef tackles—earings._ _Halyards_ are those ropes by which sails are hoisted or lowered. _Bow-lines_ are ropes fastened to the outer edge of square sails in three different places, that the windward edge of the sail may be bound tight forward on a side wind, in order to keep the sail from shivering. _Clue-lines_ are fastened to the lower corners of the square sails, for the more easy furling of them. _Reef-tackles_ are ropes fastened to the edge of the sail, just beneath the lowest reef; and being brought down to the deck by means of two blocks, are used to facilitate the operation of reefing. _Earings_ are small ropes employed to fasten the upper corners of the principal sails, and the extremities of the reefs, to the respective yard-arms, particularly when any sail is to be close furled. PAGE 68, l. 6. _Brail up the mizen quick._ The _mizen_ is a large sail bent to the mizen mast, and is commonly reckoned one of the courses, which consist of the _main-sail_, _fore-sail_, and _mizen_. As the word _brails_ is a general name given to all the ropes which are employed to haul up the bottoms, lower corners, and skirts of the great sails; so the drawing them together, for the more ready operation of furling, is called brailing them up. The effect which the operation of brailing up the mizen produces, is noticed in the last note of this Canto. PAGE 68, l. 7. _Man the clue-garnets, let the main-sheet fly!_ _Clue-garnets_ are the same to the main-sail and fore-sail, which the clue-lines are to all other square-sails, and are hauled up when the sail is to be furled or _brailed_. _Sheets_: it is necessary in this place to remark, that the sheets, which are universally mistaken by our English poets for the sails, are in reality the ropes that are used to extend the clues, or lower corners of the sails, to which they are attached.
