Hardness. The term used to indicate the 

 degree of resistance which a wood will offer to 

 outside pressure without being dented. It is 

 very hard when a pressure of 3,000 pounds per 

 square inch will not make a dent over -^ of an 

 inch deep; hard when 2,500 pounds will produce 

 this dent; fairly hard when 1,500 pounds will 

 produce it, and soft when the same dent is pro- 

 duced by less than 1,500 pounds. 



Lap siding. Lumber in 4-inch and 6-inch 

 widths, shaped as in Figure 120, page 118. 

 Made by resawing a i-inch board at an angle, 

 thus forming two pieces of siding. (Sometimes 

 known as beveled siding or clapboards.) 



Milled shapes. Lumber with other than two 

 pairs of parallel faces. 



Rf. Lumber rough as it comes from the saw. 



Rustic siding. Made of i-inch lumber 8 or 10 inches 

 wide with a shiplap joint and one or both faces machined to 

 shape.
