upper arm are for large 

 double-shed insulators 

 carrying trunk wires. 

 The top of a bolt is 

 wrapped tightly with 

 tow and the insulator 

 cup forced down upon 

 it : the resulting fixture 

 appearing everything 

 that can be desired. The 

 ornamental finials e are 

 in galvanised iron. Each 

 upright of a standard is 

 connected to earth by 

 an iron wire of 5 mm. 

 diameter. With earthed 

 single wires this is a 

 somewhat superfluous 

 precaution, but as me- 

 tallic circuits multiply 

 its utility will increase. 

 All zinc, lead, and other 

 metal about the roof is 

 put in connection with 

 the ground wire. No 

 accidents from lightning 

 are recorded in the ten 

 years of telephonic ex- 

 perience in Belgium, 

 although there have been 

 violent storms during 

 that period and many 

 buildings have been 

 struck. Single standards, 

 except when intended 

 to carry three or four 

 wires only, are usually of 

 lattice construction and
