of such a demand ; so the ultimate adoption of the British Associa- 

 tion, or divisional, plan is inevitable. That such an authority as 

 Mr. Cedergrenhas recognised the fact and adapted it to the needs 

 of the most telephonically advanced city in the world, affords 

 gratifying confirmation of the author's convictiqns. 



The backbone of the Stockholm system is the line of what 

 are called primary switch-rooms, known as Brunkeberg, Stortorget, 

 and Maria. Subscribers of Classes I., II. and III. are only con- 

 nected to these, so that they obtain amongst themselves a service 

 which never brings into requisition any of the branch switch-rooms. 

 Of these branch rooms there are four belonging to the General 

 Company and one to the Bell Company ; but as the working 

 agreement between the two concerns is of the most intimate 

 character, the Bell room practically forms part of the General 

 Company's system. The only difference is that, whereas the 

 General Company uses Ericsson's instruments for all its sub- 

 scribers, the Bell Company supplies magnetos of the American 

 type, Bell receivers, and Ericsson transmitters. To these five 

 branch rooms only members of Class IV. are joined, it having 

 been found by experience that it is only the smaller people who 

 do not make frequent use of their instruments who choose this 

 mode of subscribing ; but this class is also joined to the three 

 primary rooms when they happen to be the nearest. The three 

 primary switch-rooms are connected together by a large number 

 of junctions 1 , and each branch or secondary room possesses 

 junctions to every other room, both primary and secondary. 



On December 31, 1894, the instruments connected to this 

 extensive system numbered 9,136, divided as follows : 



General Company, Class I. ..... 3>359 



II 1*847 



HI 1,482 



IV. ... .684 



Extension lines .... 964 



Bell Company (all like Class IV. ) . . . . .800 



9,136 



By adding the 2,400 instruments of the State exchange, with 

 which all are also in connection, the telephonic circle of Stock- 

 holm city is found to possess a total membership of 11,536.
