 the centre of the city. 

 Each has direct junction 

 lines to every other, 

 there being some 700 

 wires so employed, with- 

 out counting those going 

 to the suburban rooms. 

 All these junctions are 

 single and erected over-

 come into one switch- 

 room, and are multi-

 divided from each other 

 by partitions, each of 

 which accommodates 

 two trunk lines and is 

 attended to by one 

 operator. These trunk 

 tables are a speciality of 

 Messrs. Mix & Genest, 

 who have supplied nearly 

 300 to the Imperial Ad- 

 ministration for use in 

 different towns. Fig. 68 

 shows their general ap-

 is fitted with answering 

 jacks for the trunk and 

 intermediate board wires, 

 together with forty repeat 

 jacks and the necessary indicators ; also a metallic circuit on which 

 branch switch-rooms may be put through to the trunks without 

 the intervention of a translator. The local operators notify trunk
