Spain and Russia great progress has already been made
in establishing lines Of telegraph, and communication

In India line has been laid between Calcutta and
Kedgeree Il mes and extensive system Is projected
for that country.
Tie following interesting description OF the telegraph

Of those interested in the prosecution OF telegraph lines
through somewhat similar regions of own country

coated with coal tar and PITCH and strengthened at va

wood from America The bamboo posts are found to
resist the storms which have uprooed trees the growth
OF centuIies Though the bamboo soon decays its a,a,-
ing cheapness makes the use OF more economical Than
that of durable and more costly materials. The
branch road from Bshoporet Moyapore passes through
a swamp: the country is little lees than lake for hve
months the conductor on the foot paths between
the island villages, and for some miles crosses rice

these; they possess complete immunity from gusts OF

of metal they give free passage to the electric cur

admit Of rus;ing take place without danger 10 an ex

are no more costly than thin wire and the welding

The importance OF this discovery OF the superiority Of
rods over wire will be fully appreciated in country Ike
India where the line mutt often run through bowling

this is secured by the use OF thick rods.

lines will be at tie rate OF $50 rupees mile for d1ub,
