electrified and agitated with vibrations of its own; the line
becomes spluttered and uncertain.

Various devices are employed at different stations to cure these local
complaints. The electrician soon learns to diagnose and prescribe for
this, his most valuable charge. At Aden, where they suffer much from
humidity, the mouse-mill is or has been surrounded with burning carbon.
At Malta a gas flame was used for the same purpose. At Suez, where
they suffer from drought, a cloud of steam was kept rising round the
instrument, saturating the air and paper. At more temperate places the
ordinary means of drying the air by taking advantage of the absorbing
power of sulphuric acid for moisture prevailed. At Marseilles the
recorder acted in some respects like a barometer. Marseilles is subject
to sudden incursions of dry northerly winds, termed the MISTRAL.
The recorder never failed to indicate the mistral when it blew, and
sometimes even to predict it by many hours. Before the storm was itself
felt, the delicate glass pen became agitated and disturbed, the frail
blue line broken and irregular. The electrician knew that the mistral
would blow before long, and, as it rarely blows for less than three days
at a time, that rather rude wind, so dreaded by the Marseillaise, was
doubly dreaded by him.

The recorder was first used experimentally at St. Pierre, on the French
Atlantic cable, in 1869. This was numbered 0, as we were told by Mr.
White of Glasgow, the maker, whose skill has contributed not a little
to the success of the recorder. No. 1 was first used practically on the
Falmouth and Gibraltar cable of the Eastern Telegraph Company in July,
1870. No. 1 was also exhibited at Mr. (now Sir John) Pender's telegraph
soiree in 1870. On that occasion, memorable even beyond telegraphic
circles, 'three hundred of the notabilities of rank and fashion gathered
together at Mr. Pender's house in Arlington Street, Piccadilly, to
celebrate the completion of submarine communication between London and
Bombay by the successful laying of the Falmouth, Gibraltar and Malta and
the British Indian cable lines.' Mr. Pender's house was literally
turned outside in; the front door was removed, the courtyard temporarily
covered with an iron roof and the whole decorated in the grandest
style. Over the gateway was a gallery filled with the band of the Scots
Fusilier Guards; and over the portico of the house door hung the grapnel
which brought up the 1865 c
