Water-logged. A ship is waterlogged when rendered immovable 

 by too much water in the hold. When a ship is water-logged 

 it implies that it is afloat with a cargo of wood, hence the 

 saying that the cargo often brings the ship instead of the 

 ship bringing the cargo. 



Water Streak. A dark streak in oak lumber due to injury to the 

 standing timber. 



Wattle. A hurdle formed by twigs interlaced. 



Watts and Kilowatts. Watts are the number of volts of an elec- 

 tric current multiplied by the number of amperes used. One 

 watt equals 1 ampere x 1 volt, 1,000 watts equal 1 kilowatt 

 and 740 watts are equal to 1 HP. 



Wavy Grain. An undulating grain. In maple, caused by denser 

 or darker wood cut across in sawing. 



Wayleave. An understood obligation resting on a proprietor 

 who sells standing timber to a merchant to grant wayleave 

 or arrange for a road by which the timber can be removed. 

 The time allowed for removal is a matter of mutual arrange- 

 ment. 



Weatherboard. A feather-edged board used for fencing and 

 covering of wooden ho vises. See " Clapboard." 



Wedge. A piece of wood or metal, thick at one end and sloping 

 to a thin edge at the other, used in splitting wood, etc. ; as 

 an instrument, allied with a hammer swung by manual force, 

 it exerts immense power in cleaving and lifting objects of 

 great size or weight. The use of " wood- wedges " in oil- 

 presses has declined in the presence of hydraulic presses, but 

 in the riving of billets or breaking up of timber, lathwood, 

 etc., it holds a prominent position. 



Weights of Timber. See Appendices III and IV.
