It is customary insuch cases to make what is called a scale drawing. A scale drawing may be half, quarter, or eighth size,and the fact is printed under the title in smaller letters,thus: ^ inch = 1 inch, or ^ inch = 1 inch. Other scales may be used. In map making, for ex-ample, a sixteenth of an inch may represent one, ten,or even a hundred miles. Whatever scale is used, how-ever, the dimensions must always give the exact size ofthe object represented. ELEMENTARY WOODWORKINGPaut II 49 CHAPTER V WOOD 28
