, A No. 18 soft copper wire may be used for lacing. If it is 

 hard, it can be annealed by heating it to red and plunging in 

 water. 



There are now several good makes of patented wire lacing 

 on the market. These are made up from several metals in a 

 proportion which will give a maximum degree of service. 

 Generally, they will be found superior to the copper wire. 

 When using patented wire lacing, care should be taken to fol-
