Along the whole of the line the wire is
supported on light fir and bamboo poles. The work has been carried out
with unusual celerity. From Aldershot to Chevening, a distance of
fifty miles, the line was erected in a day and a quarter, or under
thirty hours, the detachments employed having worked or marched all
night. This is, it is said, the greatest length of telegraph line ever
laid within so short a time. The result cannot fail to be useful, for
by the new line communication is now established both by telegraph and
telephone between Aldershot and Chatham. For laying such telegraph
lines to accompany calvary, a light cable is made use of. This is
carried on reels on a wheeled cart, and can be laid at the rate of six
to seven miles an hour. The Telegraph Battalion of the Royal Engineers
comprises two divisions. One is employed in time of peace under the
Post Office in the construction and maintenance of postal lines; the
other, stationed at Aldershot, is equipped with field telegraph
material.--_Daily Graphic._
