le, near the booking-office at
Euston. Wheatstone sent the first message, to which Cooke replied,
and 'never,' said Wheatstone, 'did I feel such a tumultuous sensation
before, as when, all alone in the still room, I heard the needles click,
and as I spelled the words, I felt all the magnitude of the invention
pronounced to be practicable beyond cavil or dispute.'

In spite of this trial, however, the directors of the railway treated
the 'new-fangled' invention with indifference, and requested its
removal. In July, 1839, however, it was favoured by the Great Western
Railway, and a line erected from the Paddington terminus to West
Drayton station, a distance of thirteen miles. Part of the wire was laid
underground at first, but subsequently all of it was raised on posts
along the line. Their circuit was eventually extended to Slough in 1841,
and was publicly exhibited at Paddington as a marvel of science, which
could transmit fifty signals a distance of 280,000 miles in a minute.
The price of admission was a shilling.

Notwithstanding its success, the public did not readily patronise the
new invention until its utility was noised abroad by the clever capture
of the murderer Tawell. Between six and seven o'clock one morning a
woman named Sarah Hart was found dead in her home at Salt Hill, and a
man had been observed to leave her house some time before. The police
knew that she was visited from time to time by a Mr. John Tawell,
from Berkhampstead, where he was much respected, and on inquiring and
arriving at Slough, they found that a person answering his description
had booked by a slow train for London, and entered a first-class
carriage. The police telegraphed at once to Paddington, giving the
particulars, and desiring his capture. 'He is in the garb of a Quaker,'
ran the message, 'with a brown coat on, which reaches nearly to his
feet.' There was no 'Q' in the alphabet of the five-needle instrument,
and the clerk at Slough began to spell the word 'Quaker' with a
'kwa'; but when he had got so far he was interrupted by the clerk at
Paddington, who asked him to 'repent.' The repetition fared no better,
until a boy at Paddington suggested that Slough should be allowed to
finish the word. 'Kwaker' was understood, and as soon as Tawell stepped
out on the platform at Paddington he was 'shadowed' by a detective,
who followed him into a New Road omnibus, and arrested him in a coffee
tavern.

Tawell was tried for the murder of
