town hall, the company may be 

 adjudged to have made a very 

 good bargain. Owing to the con- 

 figuration of the town hall roof 

 and the existence of a steeple, two 

 separate fixtures had to be erected. 

 These are substantially built of 

 angle-iron, the larger consisting of 

 eight uprights arranged in a square 

 of 3-3 meters and connected by 

 nineteen cross-arms. The uprights 

 are fastened solidly to the roof, and 

 the whole stands without the aid of 

 stays. The fixtures are joined to the 

 lightning conductor of the neigh- 

 bouring steeple, and, in addition, 

 have a special conductor and earth 

 of their own. All the other standards 

 in the town are carefully earthed 

 and each metallic circuit has a 

 lightning-guard, not only at the ex- 

 change, but at the premises of the 

 subscriber served by it. Fig. 86 

 shows the method of attaching the 

 insulators to the exchange cross- 

 arms. Fig. 87 shows one of the 

 standards used through the town, 

 with dimensions. The tubes are 

 continued through the roofs, and 

 are bolted or strapped to the wood- 

 work. The finials are provided with 

 holes through which, when sub-
