length for the base, another 24-ft. to form the right angle, and a 

 7-ft. length for the diagonal. Place the base on the right-angle piece 

 and put in screw (A). Measure 3 feet on the base, place diagonal as 

 sbown, and insert screw (B). Tlien measure 4 feet on the right angle 

 and 5 feet on the diagonal as depicted, bring right-angle board and 

 diagonal into position, and drive in screw (C). The remaining six 

 screws may bo placed in the square as shown. Provided the work is 

 properly executed, tlie square will be correct.
