He probably fancied that, by making so many turns and doubles, he had not only effectually puzzled all pursuit, but that his appearance at so many coffee-houses would assist him, if necessary, in proving an _alibi_; but, whatever may have been his motives or his thoughts, he had scarcely entered the lodging when the policeman--who, like a wolf, had followed him every step of the way--opening his door, very calmly said to him--the words no doubt were infinitely more appalling to him even than the scream that had been haunting him-- “HAV’NT YOU JUST COME FROM SLOUGH?” The monosyllable “NO,” confusedly uttered in reply, substantiated his guilt. The policeman made him his prisoner;--he was thrown into jail;--tried;--found guilty of wilful murder;--and--HANGED. A few months afterwards, we happened to be travelling by rail from Paddington to Slough, in a carriage filled with people all strangers to one another. Like English travellers, they were all mute. For nearly fifteen miles no one had uttered a single word, until a short-bodied, short-necked, short-nosed, exceedingly respectable-looking man in the corner, fixing his eyes on the apparently fleeting posts and rails of the electric telegraph, significantly nodded to us as he muttered aloud-- “THEM’S THE CORDS THAT HUNG JOHN TAWELL!” * * * * * Having now concluded a rough outline of the practical working of the electric telegraph, it is necessary that we should state--as an important fact on which we offer no comment--that the Company has made arrangements with all the railway companies for working their wires, excepting with the South-Eastern, and, accordingly, that the electric communication between London and Dover is worked by itself, and without connexion with the general system. The wires of the electric telegraph from the various lines of railway, carried under the streets, and concentrated at the central station in London, transmit private messages and answers to and from the following places:-- Acklington. Alne. Alnwick. Ambergate. Apperby. Ardleigh. Ashchurch. Attleborough. Audley End. Aycliffe. Ayton. Barking Road. Barnsley. Beeston. Belford. Belmont. Belper. Bentley. Berwick-on-Tweed. Beverley. Birmingham. Bishopstoke. Blackwall. Bradford. Braintree. Brandon. Brentwood. Bridlington. Brick Lane. Brockley Whins. Brockenhurst. Bromsgrove. Brough. Broxbourne. Burton-on-Trent. Calverley. Cambridge. Castleford. Chelmsford. Cheltenham. Chesterfield. Chesterford. Chittisham. Church Fenton. Clay Cross. Cockburnspath. Colchester. Colwich. Cowton. Crewe. Croft.
