drawn in. The conduits now being laid have an ultimate capacity 

 of 8,000 metallic circuits, and consist partly of cement blocks, 

 with ducts for the cables, and partly of small iron tubes stacked 

 together, the object being in each case to provide a separate 

 channel for each cable, an object which cannot be too strongly 

 commended. The cables, which in the centre of the town convey 

 nearly one-third of the total number of subscribers, have hitherto 

 been chiefly of the ' anti-induction ' type, i.e. the single wires are 

 insulated with india-rubber and sheathed with metal foil joined 

 to earth ; but in connection with the new exchange the cables 

 will be all paper-insulated, with conductors of '8 mm. copper, 

 and a capacity of '05 microfarad per kilometer, the wires being 

 laid up in twisted pairs. There are a few aerial cables, each con- 

 taining fifty-two twisted pairs of copper conductors, '8 mm. copper, 

 insulated with paper, capacity '05 microfarad per kilometer, pro- 

 tected by lead, and hung from stranded steel suspenders. 



OUTSIDE WORK (TRUNK) 



The trunk lines which radiate from Copenhagen to every 

 town and village of Zealand are mostly metallic circuits built of 

 2 mm. hard-drawn copper, the wires being crossed at intervals to 

 counteract induction. The poles are wood, and the insulators 

 double-shed ; as a rule, the routes, which follow the country roads, 

 are both substantial and neat. The Government line to Sweden, 

 via Vedbok, is of 3 mm. high conductivity bronze wire, twisted 

 on the Moseley-Bottomley plan. On the Swedish side the con- 

 struction is with 3 mm. hard copper, the two sections being 

 joined by an old four-line telegraph cable with parallel wires. The 

 Danish section of the projected line to Hamburg is to be of 

 4 mm. high conductivity bronze with twisted wires, but the 

 twelve-mile submarine section between Zealand and Funen will in 

 this instance also be an old telegraph cable.
