Glass Cutter.^ — There will be occasions for 

 cutting glass. You often need a piece of glass, 

 and a moderate-size cutter will save a deal of 

 exasperation. To cut glass, lay it on a perfectly 

 smooth surface, and then hold a straight edge 

 where you want to cut. Draw the cutter wheel 

 once with a steady, firm pressure. Never try to 

 cut over again on the same place. After you 

 have marked the surface, turn the glass over and 

 tap very lightly along the line with something 

 light and hard. The glass will then part readily.
