LEE 



LEE 



a genus of the Triandria Trigynia class 

 and order. Natural order of Caryopbyllei. 

 Essential character : calyx three-leaved ; 

 petals three, linear; capsule three-celled, 

 three-valved, with as many internal ones ; 

 seeds solitary. There are three species, 

 natives of North America, and of China 

 near Canton. 



LECYTH1S, in botany, a genus of the 

 Polyandria Monogynia class and order,, 

 Natural order of Myrti, Jussieu. Essen- 

 tial character : calyx six-leaved ; corolla 

 six-petalled ; nectary ligulate, stamini- 

 ferous ; pericarpium circumcised, many- 

 seeded. There are six species. These 

 are trees or shrubs, with alternate leaves ; 

 flowers in terminating spikes from the 

 axils of the shoots. It is peculiar to this 

 genus to have a pitcher-shaped body in 

 the centre of the flower, which Linnxus 

 calls the nectarium, inserted into the 

 calyx below the petals, perforated in the 

 middle for the passage of the style, 

 shaped like a petal, coriaceous entire at 

 the edge, but covered on the inside with 

 numerous subsessile stamens. Native of 

 the forests of Guiana. 



LEDUM, in botany, a genus of the De- 

 candria Monogynia class and order. Na- 

 tural order of Bicornes. Rhododendra, 

 Jussieu. Essential character ; calyx five- 

 cleft; corolla flat, five-parted; capsule 

 five-celled, gaping at the base. There 

 are three species, all natives of the North 

 of Europe. These shrubs growing on 

 mosses or bogs, where the roots spread 

 freely, cannot be preserved in gardens, 

 as least so as to thrive, but in a proper 

 soil and a shady situation. 



LEE, an epithet to distinguish that half 

 of the horizon to which the wind is direct- 

 ed from the other part whence it arises, 

 which latter is accordingly called to wind- 

 ward. This expression is chiefly used 

 when the wind crosses the line of a ship's 

 course, so that all on one side of her is 

 called to windward, and all on the oppo- 

 site side to leeward; and hence " Lee 

 side," all that part of a ship or boat which 

 lies between the mast and the side 

 farthest from the direction of the wind ; 

 or that half of a ship which is pressed 

 down towards the water by the effort of 

 the sails, as separated from the other half 

 by a line drawn through the middle of 

 her length : that part of the ship which 

 lies to the windward of this line is accord- 

 ingly called the weather-side. Tims, if a 

 ship sail southward with the wind at east, 

 then is her starboard, or right side, the 

 lee-side ; and the larboard, or left, the 

 Weather-side.

LEE wrtz/, or LEEWARD "way t is the la- 

 teral movement of a ship to the leeward 

 of her course, or the angle which the line 

 of her way makes with her keel when she 

 is close hauled. This movement is pro- 

 duced by the mutual effort of the wind 

 and sea upon her side, forcing her to lee- 

 ward of the line upon which she appears 

 to sail, and in this situation her course is 

 necessarily a compound of the two mo- 

 tions by which she is impelled. All ships 

 are apt to make some lee-way ; so that in 

 casting up the log-book something must 

 be allowed for lee-way. But the lee-way 

 made by different ships, under the same 

 circumstances, will be different : and even 

 the same ship, with different lading, and 

 having more or less sail on board, will 

 make more or less lee-way. 



However, the common allowances made 

 for lee-way, are these : 1. If the ship be 

 close hauled, has all her sails set, the 

 water smooth, and a moderate gale of 

 wind, she is supposed to make little or no 

 lee-way. 2. If it blow so fresh, as to 

 cause the small sails to be handed, it is 

 usual to allow one point. 3. If it blow so 

 hard, that the tops must be close reefed, 

 the ship then makes about two points lee- 

 way. 4. If one topsail must be handed, 

 it is common to allow two and three 

 quarters, or three points lee-way. 5. 

 When both topsails must be handed, 

 they allow about four points lee-way. 

 6. When it blows so hard, as to occasion 

 the fore-course to be handed, the allow- 

 ance is between five and a half and six 

 points. 7- When both main and fore- 

 courses must be handed, then six, or six 

 and a half points must be allowed for her 

 lee-way. 8. \Vhen the miien is handed, 

 and the ship is trying a hull, she then 

 makes her way good about one point be- 

 fore the beam," that is, about seven points 

 lee-way. 



Though these rules are such as are 

 generally used, yet as the lee-way depends 

 much upon the mould and trim of the 

 ship, we shall here give the method of 

 ascertaining it by observation. Thus, let 

 the ship's wake be set by a compass in 

 the poop, and the opposite rhumb is the 

 true course made good by the ship ; then 

 the difference between this, and the 

 course given by the compass in the bit- 

 tacle, is the lee-way required. If the 

 ship be within sight of land, the lee-way 

 may be exactly found by observing a 

 point on the land which continues to bear 

 the same way ; for the distance between 

 the point of the compass it lies on, and the 

 point the ship capes at, will be the lee-way.
