that he will be called upon to execute by aid 

 of the square. 



These squares are furnished by the manufac- 

 turers either in polished steel, nickel plate or 

 oxidized copper. The latter style is quite pop- 

 ular with some workmen, because of its not get- 

 ting so hot when exposed to the rays of the sun. 



The two sides of the square, shown at Fig. 3, 

 represent the carpenters' popular square, No. 



100. This square has been a 



special favorite with workmen 



for nearly thirty years, and is 



still looked upon by many as 



being the ne plus ultra of steel 



squares. I show both sides of the 



square in order to enable the 



workman to see, before he buys, 



the kind of tool he will get. 



Like the Nicholls square, this 



may be obtained in polished Flg * 4> 



steel, nickel plated, or oxidized copper as the 



purchaser may desire.
